It looks like CFexpress will be the standard of future memory cards for internal high resolution RAW video recording, because the theoretical maximum speeds are ridiculously high. Back in April 2018, ProGrade showcased what is possible with CFexpress technology – they demonstrated their 1TB 1400MB/s CFexpress type B card.

CFexpress 2.0

In February 2019, CompactFlash association released specifications for the CFexpress 2.0 standard (full press release available here). Memory cards with this new standard will come in three sizes – type A (20 x 28 x 2.8mm), type B (38.5 x 29.8 x 3.8mm), and type C (54 x 74 x 4.8mm). The maximum theoretical performance for CFepxress cards is 4000MB/s for the largest type C, 2000MB/s for the middle type B, and 1000MB/s for the smallest type A cards.

The new SanDisk memory cards are CFexpress 2.0 type B, which have identical form factor as XQD cards. Sometimes these cards are being referred to as “the next version of XQD”. It seems that CFexpress cards can be supported through firmware update with XQD compatible cameras. Nikon, for example, announced that future support for CFexpress is coming via a firmware update to their Z 6 and Z 7 mirrorless cameras. Other popular cameras with XQD slot are Panasonic S1, S1R, and Sony FS7. We don’t have any information yet whether Panasonic and Sony are also planning to bring CFexpress support for these cameras.

SanDisk Extreme PRO CFexpress Cards

The new SanDisk Extreme PRO CFexpress type B memory cards come in four different capacities – 64GB, 128GB, 256GB, and 512GB. When it comes to speeds, SanDisk has rated the 128GB, 256GB, and 512GB models at 1700 MB/s read and 1200 MB/s write, while the 64GB model hits 1500 MB/s read and 800 MB/s write.

These speeds should be enough for RAW 4K video recording. I am very curious if we will see internal RAW video recording in the Nikon Z6 and Z7, for example.

SanDisk CFexpress Card Reader

The SanDisk CFexpress type B card reader uses USB 3.1 Gen 2 Type-C interface and it comes with the USB Type-C cable. Maximum transfer speed will be 1250 MB/s, which will depend on the speed of the card itself and the speed of the computer drive.
