After plugging in my USB flash drive, why doesn’t my computer recognize it?

Please re-attach the flash drive and run the application again.

Why does the flash drive show less than the total capacity?

The total capacity is divided up between the public partition and secure partition. Users can change the capacity of the secure partition once their fingerprints have been authenticated.

Can the secure partition of the flash drive be accessed through my smartphone?

Only the public partition can be accessed through your smartphone.

Why can’t files larger than 4GB be saved to the flash drive?

The initial format of the F35 is FAT32; you need to re-format it to exFAT when transmitting files larger than 4GB. Please note all files on the drive will be lost if you re-format. However, the fingerprint application itself, will not be erased.

What systems are compatible with the fingerprint application?

The fingerprint application can be operated in Windows XP, Windows Vista, Windows 7, Windows 8, Windows 10.

What are the minimum requirements to set up an admin/user account or change the partition size of the drive?

The fingerprint application requires Windows XP and up.The fingerprint application is required to setup any accounts or changes to the partition size.

If I have an older version of Windows, Mac OS, or Linux, can I still access the public and secure partitions?

Regular flash drive use is compatible with Windows, Linux, and macOS.

Why does the secure partition disappear after 15 minutes?

The secure partition is designed to close after 15 minutes of inactivity for security purposes. To re-access the secure partition, simply place an authorized fingerprint on the sensor and it will re-open.

What type of encryption is used on the Lexar F35 fingerprint flash drive?

Encryption is based on the 256-bit AES method. The fingerprint data is saved on the flash drive with an exclusive UID produced by FP IC. Since the fingerprint data and fingerprint algorithm is separate, the data saved in the secure partition will be lost if the flash drive is dismantled by force.

How many chances do I have to enter my administrator password correctly?

If the user enters an incorrect password more than 254 times in succession, the F35 will start the process of self-destruction. All data in the USB flash drive will be erased, and the F35 can only be recovered by downloading the firmware again.

Why can’t I access the secure partition after placing my finger on the fingerprint sensor several times?

Ensure your fingerprint and sensor are clean and dry. If that doesn’t work, try re-attaching the flash drive.

Why doesn’t the Lexar USB flash drive support files that are 4GB or larger?

To transfer files larger than 4GB, the USB flash drive must have an NTFS or exFAT file system. The default file system for the USB flash drive is FAT32, which cannot handle single files larger than 4GB (more precisely, one byte smaller than 4GB). Please follow the steps below to format the USB flash drive using the NTFS file system: Warning: all data on the USB flash drive will be lost! Before continuing, please backup the data on the USB flash drive.

1. Open “My Computer” (“Computer” for Vista and 7). Right click on the Lexar USB flash drive and select “Format”.

2. Select NTFS or exFAT from the file system drop-down list.

3. Select “Quick Format” as the format option and click “Start”. Note: If NTFS is not available, close the “Format” window and follow steps 4-9.

Although booting from the USB flash drive is possible, this is not a feature supported by Lexar. The USB flash drive is designed to be used as a storage device. Does the Lexar USB flash drive have write protection? The Lexar USB flash drive does not offer write protection. If you experience write protection messages when using the USB flash drive, please check the following:

1. Confirm that you are allowed to write to the removable storage device. There may be security settings in the operating system that disable write access to removable storage devices.

2. Confirm if you have used third-party software to enable write protection on your USB drive. If none of the above is true, then the USB flash drive may be faulty. Please contact our technical support for further assistance. Is USB3.0 the same as USB3.1? USB3.1 is a specification developed by the USB-IF. USB3.1 includes USB3.1 Gen1 and USB3.1 Gen2: USB3.1 Gen1 (SuperSpeed): The highest theoretical transfer speed is 5 Gb/s (equivalent to USB3.0). USB3.1 Gen2 (SuperSpeed+): The highest theoretical transfer speed is 10 Gb/s. The actual speed is based on product specifications.

The USB flash drive is not recognized by the computer. What should I do?

Please check if the USB port on your computer is functioning normally and whether the flash drive driver is mounted. If the port function and driver are normal and the USB flash drive still cannot be recognized, please contact our technical support.

Some USB flash drives with metal casing are hot after hours of use. Is this normal?

Heating up is normal for USB flash drives. Temperature may vary between metal casing and plastic casing due to the metal casing absorbing more heat.

What are the transfer rates of USB1.0, USB1.1, USB2.0, USB3.0, and USB3.1?

What is a USB Type-C connector?

USB Type-C, also known as USB-C, is a universal serial bus (USB) connector. The biggest feature in appearance is that both ends are completely identical. Compared with the Micro-USB, this means that users do not have to find the correct orientation as both ends can be inserted. USB Type-C supports OTG, that is, in the absence of a host (such as a personal computer), data can be directly transferred between portable devices. It can support up to USB 3.1 specifications and is backward compatible.

What is a Micro USB connector?

It’s a substitute for the Mini-USB on many smart phones and tablets, is half the height of the Mini-USB plug, and nearly as wide. Micro-USB supports OTG, that is, in the absence of a host (such as a personal computer), data can be directly transferred between portable devices. It is compatible with USB1.1 and USB 2.0 specifications.

What is the correct way to use the USB flash drive?

Is there a difference between USB 2.0 and USB 3.1 in storing data?

The theoretical data transmission speed of USB2.0 is slower than that of USB 3.1, but the function of storing data is no different. Please note that the USB 3.1 standard USB drive or port is backward compatible with the USB2.0 interface.

The computer only has a USB 2.0 port. Can I use a USB 3.0 USB flash drive?

USB3.0 is backward compatible with USB2.0, so reading and writing data will not be affected. However, the use of a USB3.0 USB drive in a USB2.0 port will limit the transmission speed.

How do I check the capacity of my USB flash drive?

Please go to “My Computer”, right click on the USB flash drive icon and click “Properties” to display the capacity of the flash drive device. You can also confirm the capacity of the USB flash drive through “Disk Management” in “Computer Management”. (The function names may be different for different computer systems.) How does the USB flash drive store data? The USB flash drive uses NAND Flash as a component for storing data. The NAND Flash stores data by means of charging and discharging (writing/erasing). This type of storage device has the advantages of lighter weight, smaller size, lower power consumption, shock resistance, and better performance than traditional hard disks.

How do I change the name of the USB flash drive?

However, you can expect to see the best performance possible when using a well-equipped computer and a card with fast transfer speeds. Using the Thunderbolt 2 hub, you can expect to see even faster performance. Theoretical limits establish USB 3.0 at 5gbps and Thunderbolt 2 at 20gbps. Therefore, you can generally expect to see up to 4x the performance depending on all the inputs listed above. Performance can greatly vary depending on card speed and the specs of your computer system. Why is it better to include a hub in my setup, rather than using a standalone single-slot reader? The main advantage is that you’ll save time with the ability to transfer data from multiple cards at once (concurrent transfer). With a single-slot reader, you can only transfer content one card at a time (consecutive transfer). With the hub fully populated with your choice of reader or hub modules, you can offload your work, faster. This lets you get to editing, sharing, and eventually back to shooting much sooner.

Can I mix and match the reader combination I want?

Yes, that’s one of the biggest advantages of using the Lexar Professional Workflow line—the ability to design a custom setup that fits your specific needs. For example, a Nikon D4 shooter may want two CompactFlash (CF) readers and two XQD 2.0 readers, whereas a Canon 5D Mark III shooter may want three CF readers and one SD UHS-II reader. Others may want one or more of the two-port USB 3.0 hubs as part of their workflow setup. Who is this line designed for? This product line was created with professional photographers, videographers, and enthusiasts in mind. It’s an excellent choice for those shooting with multiple cards, or using multiple cameras/video cameras. With the ability of today’s cameras to capture RAW images, high-res photos, 4K video, and beyond, there is a need for faster, higher capacity cards, and quicker transfer of large amounts of data from multiple cards. Now these functions can be done concurrently. And the two-port USB 3.0 module allows you to connect USB flash drives or additional readers, and even charge those devices. Setup and Use Can I use the power adapter that came with my Professional Workflow HR1 with HR2? No, the Professional Workflow HR2 hub requires more power and therefore comes with a larger power supply. Please do not mix the power supplies between the units.

Can I use the readers without the hub?

Yes, each reader package includes a USB cable so you can use them on their own. This makes them an excellent on-the-go solution.

Can I use the reader and two-port USB 3.0 hub modules without the HR1 and HR2 hubs?

Yes, each module package includes a USB cable so you can use them on their own. This makes them excellent on-the-go solutions.

How does the daisy-chain feature work using the Professional Workflow HR2 hub?

To conveniently daisy-chain the hub anywhere in your lineup, you can use both Thunderbolt 2 ports on the back of the hub. Simply connect one Thunderbolt 2 cable from the hub to your computer or other device and then connect the hub to the Thunderbolt 2 cable from the next device, such as a monitor or hard drive. Thunderbolt 2 technology allows for up to six devices to be daisy-chained to one port on your computer. To ensure the best performance, consider placing your hub at the beginning of the chain, closest to your computer.

Why do the LEDs on my readers blink?

This indicates that the reader is in the process of transferring data from your card to your computer. When your reader’s LED is blinking, do not remove the card or remove the reader from the hub.

Are there any recommended reader-specific configurations when using the hubs?

Photographers and videographers who are shooting solely with CompactFlash (CF)-based cameras will likely want to purchase four CF readers. Nikon D5 shooters will likely want two CF and two XQD 2.0 readers (assuming they are using both slots in their camera). Canon DSLR users will likely want a combination of CF and SD UHS-II readers (since some Canon cameras tend to use either of both form factors). Many photographers use CF-based cameras for their primary camera and a point-and-shoot camera for general use or scouting. These shooters may also want a combination of CF and SD readers in their hub.

Why is a USB type B connector used?

This connector is durable and provides for solid, smooth insertion and removal of the readers in and out of the hub.

Does the Professional Workflow HR1 or HR2 hub need to be plugged into AC power to work?

Yes, in order for either hub to work correctly, it must be plugged in. There is not enough power supplied from the USB port on a computer to power this device.

Why am I getting a series of ‘Drive removed incorrectly’ messages after my Mac wakes from hibernation?

Occasionally, the hub may not be recognized after waking. If this happens, please unplug your HR1 or HR2 hub from your Mac and plug it back in. If this doesn’t resolve the issue, you may need to restart your computer.

You don’t provide a power adapter that complies with my country’s regulatory guidelines. How can I use the Professional Workflow HR1 or HR2 hub?

We’ve worked diligently to provide as many region-specific adapters as possible, but we’re unable to meet the need in every country. If you are in one of these regions, you can purchase a travel converter that meets your country’s international power adapter needs to use with the power supply provided with your Professional Workflow Reader HR1 or HR2 hub. Please ensure that the adapter you purchase meets the requirements of your country’s power adapter guidelines.

Why do I get an error message on my computer saying that I do not have enough power to transfer files when using one of the Lexar Professional Workflow hubs?

This error occurs when the power cord is not connected to the Professional Workflow HR1 or HR2 hub, or the power supply is not connected to a wall outlet or a power source. Properly connect the hub to resolve the error.

What card formats do the Professional Workflow readers support?

Currently, the product line includes readers that support SD UHS-I and UHS-II, CompactFlash UDMA 7, CFast or CFast 2.0 (Thunderbolt or USB 3.0), XQD 2.0, and microSD UHS-I and UHS-II formats. And for versatility, the CFast 2.0 reader is backwards compatible with the 1.0 format (at 1.0 speeds). As technology evolves and we launch new card formats, we’ll also create new readers for this product line. This ability to purchase new reader formats helps to future-proof your workflow setup and save you money.

Will my first-generation XQD card work in the Professional Workflow XR2 (XQD 2.0) reader?

Can I use the Professional Workflow SR2 (SD UHS-II) reader with my SD UHS-I memory cards?

Yes, the reader is fully backwards-compatible with SD UHS-I cards (at UHS-I speeds), so you can use both SD UHS-I and UHS-II cards with the reader.

Can I transfer data from three microSD cards at the same time using my Professional Workflow UR2 reader?

Yes, if you plug a reader directly into a computer with the included USB 3.0 cable you can transfer data from each card concurrently. This is also possible using the Professional Workflow HR2 (high-speed Thunderbolt 2) or HR1 (USB 3.0) hub. NOTE: First-generation Professional Workflow HR1 hubs (Rev A) only support up to two Professional Workflow UR2 readers at once. To find the Professional Workflow HR1 model you’re using (Rev A or Rev B), check the label on the bottom of the product.

How many Professional Workflow UR2 (three-slot microSDHC/microSDXC UHS-I) readers can I use with the HR1 and HR2 (four-bay) hubs?

Why is memory important to digital cameras?

As picture quality and resolutions on digital cameras have improved, the need to save and store larger photo and video files has increased. Earlier versions of digital cameras often featured built-in, non-expandable memory for storing pictures and video. Memory capacity of these cameras could be reached quickly, forcing users to download pictures constantly to their computers or erase pictures before taking another photograph. This is very inconvenient for users who want to use their cameras without having a computer nearby. Today’s leading digital camera manufacturers typically feature removable digital film cards for capturing, storing, and swapping images. Popular removable memory solutions include SD, microSD, CompactFlash, and CFast. Typically, camera manufacturers include a minimum-capacity card with the camera, just enough memory to provide a good out-of-the-box experience for the user. As the capacity of that card is reached, either the user must download the photos to a computer, erase pictures, or replace the card to continue taking pictures. That’s why for many typical picture-taking situations like vacations, weddings, or sporting events, the digital photographer needs more digital film.

What are the popular types of digital film today?

Digital film uses non-volatile flash memory, meaning it does not require power to store the pictures taken. Flash memory technology is ideal for applications that require portability and ruggedness. There are three main types of flash memory used for digital cameras today: SD, microSD, CompactFlash, and CFast formats. Secure Digital (SD): The size of a postage stamp, SD cards are compact and flexible for use in multiple consumer electronic devices. Its ability to deliver high performance allows consumers to quickly capture photo and video files in a reliable and easy-to-use format. microSD: The smallest memory card that can be bought, which is about a quarter of the size of a normal-sized SD card. microSD cards are used in mobile phones, tablets, action cameras, drones and other mobile devices. CompactFlash: A small form factor (about the size of a matchbook) that combines non-volatile storage, high-capacity options and industry-standard compatibility, which is absolutely essential for digital cameras and handheld computing devices. Because they are designed to the guidelines set by the CompactFlash Association, a base-level assurance of compatibility has been set between all-certified CompactFlash cards and any CompactFlash-compliant device. CFast: The latest evolution of card format from the CompactFlash Association and provides a higher maximum transfer rate than CompactFlash® cards. CFast cards are similar in size to CompactFlash cards, but do not have any pins which can bend in the connector. The format was primarily designed to support the capabilities of next-generation of camcorders and DSLR cameras.

What is the CompactFlash Association?

The CompactFlash Association (CFA) was established in 1995, as a non-profit, mutually beneficial industry association. The CFA’s premise is that CompactFlash technology will result in the intro-duction of a new class of advanced, small, lightweight, low-powered mobile products that will significantly increase the productivity and enhance the lifestyle of millions of people. CompactFlash provides the capability to easily transfer all types of digital information and software between a large variety of digital systems. The goals of the CFA are to promote and encourage the worldwide adoption of CompactFlash technology as an open-industry standard. Information on the CompactFlash Association can be found at http://www.compactflash.org Is performance important when talking about digital film? As digital camera applications, camera resolutions, and picture and video file sizes continue to grow, the ability to both WRITE and READ large files have become critical performance requirement. Improved WRITE performance can significantly reduce the waiting time before another photograph can be taken (“image storage time”). Improved READ performance can significantly reduce the waiting time for photo and video files to be transferred to your computer–saving time and improving digital photography “workflow.” Lexar SD, CompactFlash and CFast cards significantly reduce file transfer time to your computer AND the time a picture file can be written to the card. While actual performance will vary between camera models, Lexar offers high-speed performance so you never miss the memories you want to save: a baby’s smile, a wedding kiss, or any other precious moment. What does 633x, 667x, 1000x, 1066x, 1667x, 1800x, 2000x and 3500x (1x=150KB/s) performance mean? Because digital film performance is so important in capturing the right picture at the right moment, Lexar has implemented an easy-to-understand system to indicate the speed at which the card is capable of storing data. The system is adopted from the CD-ROM industry, in which the performance of CD-ROM drives are rated in “x” increments, where 1x is equal to a sustained write speed capability of 150 kilobytes per second (KB/s). Lexar will continue to introduce faster products with greater “x” ratings, giving consumers an easy way to recognize the latest in high-performance digital photography. 633x = Up to 95MB/s read transfer, write speeds lower 667x = Up to 100MB/s read transfer, write speeds lower 1066x = Up to 160MB/s read transfer, write speeds lower 1667x = Up to 250MB/s read transfer, write speeds lower 1800x = Up to 270MB/s read transfer, write speeds lower 2000x = Up to 300MB/s read transfer, write speeds lower 3500x = Up to 525MB/s read transfer, write speeds lower.

FAT32, ExFAT, NTFS, and Extended Journaled are some of the most common examples of file systems, which are methods by which data is arranged on a storage device. Very simply, the differences are as follows: FAT32 – 4GB (gigabyte) maximum file size and maximum storage device size can be as low as 2TB (terabytes). Compatible with both Mac and Windows. Typically used for legacy Operating Systems and older devices. ExFAT – A newer iteration of FAT32, requiring newer devices and operating systems, but effectively removing the file size limits and device size limits (ExFAT supports hundreds or thousands of terabytes). NTFS – Windows-specific, though has limited support in OS X. Typically used on a fixed hard drive, rather than removable storage. Like ExFAT, has less restrictive file size limitations, but due to its status as a primarily Windows-based file system, NTFS can conflict with non-PC hardware. Extended Journaled – Mostly Apple-specific when dealing with consumer products, and has limited support outside OS X/iOS platforms. Typically used as an Apple OS drive, with removable storage being formatted as FAT32/ExFAT instead. For best compatibility and interoperability of your Lexar storage product across multiple devices (especially non-PC devices, such as media readers built into TVs, Blu-Ray players, DVRs, etc.), we recommend formatting your device as ExFAT or FAT32. Specific hardware may require other file systems, however, including ones not listed here. For more information on a given device’s needs, please see your device’s documentation or manufacturer support for more details.

Can my data be fully recovered?

We cannot guarantee one hundred percent recovery of your data, but in most cases the data can be recovered normally using our software.  

I have recovered the file, but I am unable to open it?

When this situation occurs, it could be due to the following reasons: (1)The file has been corrupted After a file has been deleted, it can be corrupted or overwritten by another file. Defragmentation, virus attacks or hacker activity will cause the file to be corrupted. (2)Fragmented files Some large files are stored in separate sectors on the hard drive, since they are too large be allocated to continuous sectors of the storage space. When the data from one or more sectors has been deleted, recovery is very difficult. Even if the initial address is accessible, the address information of the erased data is often lost.  

How long does data recovery normally take?

It depends on the size of the storage space and the size of the data. The larger the data, the longer it will take; contrariwise, the smaller the data is, the shorter it will take.  

Precautions

Before using the Lexar Recovery Tool software, the success rate of recovering your files greatly depends on how the storage device is used, and whether there were any new written data after the accidental deletion.   Do not continue to work on the storage device with the lost data on it! (1) You should not continue to use the drive which contains the accidentally deleted files. (2) Do not use operations such as copy, cut, or paste on the drive. (3) The more actions that have been done on the drive, the lower the success rate of recovery. (4) If recovery of lost data is needed, please do not defrag the drive or execute any tool that can possibly do further damage to the drive. Otherwise, it could erase the data of the file on the drive that you want to recover.

Device not working in windows If a storage device is malfunctioning regardless of what hardware or interfaces it is connected to, most common issues are caused by improperly removing the storage device from your computer or its card reader, corruption, an improper drive letter assignment, or a driver error. With the device connected, right-click the bottom-left corner (or Start button) on the desktop to open a Quick Access Menu, and then choose Device Management. In Windows 7 and earlier, open your start menu and search for Device Manager, then select it. – Click on the + sign next to Disk Drives, Other devices, and Universal Serial Bus controllers – Check if the Lexar storage device is listed in any of those places – If the device is listed, check whether there is a yellow exclamatory mark (!) or a question mark (?) next to it. – If there is yellow exclamatory mark (!) or a question mark (?) next to the device, right-click on it and select remove/uninstall. Unplug the device and reconnect it the computer should detect it automatically, if it has appropriate drivers If there is no yellow (?) or (!) mark on the Lexar storage device then you need to confirm/change the drive letter for the memory card/JumpDrive. You must have administrator privileges for your local computer in order to change drive letters under Windows. Right-click the bottom-left corner (or Start button) on the desktop to open Quick Access Menu, and then choose Disk Management. In Windows 10 and earlier, open your start menu and search for “Create and format Hard Disk Partitions.” – At this point it will appear your screen is divided into two separate areas. Please maximize the screen and focus on the bottom portion. You will see a listing that says something similar to the following. “Disk 0, Healthy, Primary, Active Partition.” – this will be your Hard Drive. You will also see any other drives you may have listed here, such as Recovery Drives, any External Hard Drives and your CD/DVD Drives. – Please check for any other Disk Numbers. For example, your memory card or Jumpdrive may show up as Disk 1, Removable. It will also list a capacity close to your memory card, for example a 4GB memory card should show around 3.7GB. – If the device is still not listed or it states “No Media”, the device’s controller or its connection to your system is malfunctioning. Try the storage device in another system or port, but if that does not help please contact us for further support. If it shows as unallocated, your partition has been damaged, and needs to be reformatted to continue using the device. – If neither of the above applies, right-click on the device and select “Change Drive letter and Paths” then click on “Change” and assign drive letter Z and then click on “Ok,”“Yes,” then “Ok.” If none of the above resolves your malfunction, please contact us for additional support. Device not working in OS X If the Lexar device is not working normally in the Mac OS, regardless of what hardware or interface you are connecting it through, please try the following steps:

FAT32, ExFAT, NTFS, and Extended Journaled are some of the most common examples of file systems, which are methods by which data is arranged on a storage device. Very simply, the differences are as follows: FAT32 – 4GB (gigabyte) maximum file size and maximum storage device size can be as low as 2TB (terabytes). Compatible with both Mac and Windows. Typically used for legacy Operating Systems and older devices. ExFAT – A newer iteration of FAT32, requiring newer devices and operating systems, but effectively removing the file size limits and device size limits (ExFAT supports hundreds or thousands of terabytes). NTFS – Windows-specific, though has limited support in OS X. Typically used on a fixed hard drive, rather than removable storage. Like ExFAT, has less restrictive file size limitations, but due to its status as a primarily Windows-based file system, NTFS can conflict with non-PC hardware. Extended Journaled – Mostly Apple-specific when dealing with consumer products, and has limited support outside OS X/iOS platforms. Typically used as an Apple OS drive, with removable storage being formatted as FAT32/ExFAT instead. For best compatibility and interoperability of your Lexar storage product across multiple devices (especially non-PC devices, such as media readers built into TVs, Blu-Ray players, DVRs, etc.), we recommend formatting your device as ExFAT or FAT32. Specific hardware may require other file systems, however, including ones not listed here. For more information on a given device’s needs, please see your device’s documentation or manufacturer support for more details.

What is the warranty of Lexar products?

Lexar offers different warranty period for each product. Please refer to our Warranty Policy for details at https://www.lexar.com/support/warranties/

While CFexpress Type B cards and XQD cards can fit in the same slot, compatibility depends on the host devices. Please check compatibility of your host device with your manufacture.

The difference between the three cards are the form factor, number of lanes and maximum performance. Currently the most used card is the Type B due to its similarities in size with XQD cards.

CFexpress is the latest standard for removable media cards proposed by the CompactFlash Association. The standard uses PCIe 3.0 interface with 1 to 4 lanes where 1 GB/s data can be provided per lane. NVM Express is also supported to provide low overhead and latency. For more information, click here https://www.compactflash.org/cfexpress

A constant writing speed class for video recording. There are three kinds of Speed Classes, “Speed Class”, “UHS Speed Class” and “Video Speed Class.” This Speed Class provide the constant speed necessary for video recording by designating a minimum writing performance, this include V6、V10、V30、V60 and V90. V6 Speed Class means that the minimum write speed of the memory card needs to reach 6MB/s, V10 is 10MB/s, 30 is 30MB/s, and so on. V60 and V90 can be applied to high resolution and high quality 8K video recording, and V30 can be applied to 4K resolution. SD makers will print these speed class symbols on memory card (V60, V90…etc.). These speed class symbols will be applied to SDHC, SDXC, UHS-I, UHS-II and SD memory card help users decide the best combination for reliable recording.

It is used for smartphone application performance classification. Application Performance Class 1 (A1) and Class 2 (A2) defines the minimum average of random read/write IOPS. IOPS specification of A1 is read 1500IOPS /write 500IOPS, and the minimum sustained sequential performance is 10MB/s. IOPS specification of A2 is several times faster than A1. The random read is 4000IOPS, and the random write is 4000IOPS. That means the write performance of A2 is faster than A1 read performance, and the minimum sustained sequential performance is also 10MB/s.
