What is CFexpress?

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

What is the difference between CFexpress Type a, Type b, Type c cards?

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.  width=

Are CFexpress type b cards the same as XQD cards?

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.

JumpDrive® Fingerprint F35 Flash Drive FAQs

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.

What is VPG-20/ VPG -65?

 width= The VPG-20 logo represent adherence to the Video Performance Guarantee-20 specification for professional-quality video. When used with a compatible camera, the VPG-20 logo on a card means that the system has been tested and guaranteed for professional video capture streams at up to 20MB/sec. This enables professional-quality video capture at high frame rates with no dropped frames.  width= The VPG-65 logo represent adherence to the Video Performance Guarantee-65 specification for professional-quality video. When used with a compatible camera, the VPG-65 logo on a card means that the system has been tested and guaranteed for professional video capture streams at up to 65MB/sec. This enables professional-quality video capture at high frame rates with no dropped frames.

What is the V30/V60/V90 video speed class?

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.  width=  width= *Source: SD Association

What is A1/A2 application performance class?

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.  width= *Source: SD Association
