CFexpress playing cards preserve getting sooner… besides proper now, they are not. For the reason that introduction of the CFexpress 4.0 normal we have seen Sort B playing cards able to speeds approaching 3800MB/s, however there’s little or no headroom to go any sooner, as absolutely the theoretical pace restrict of model 4.0 is 4.0GB/s, or 4000MB/s. So with a bunch of Sort B playing cards all hitting the technological pace buffers, how do you stand out from the group?
Nextorage could have the reply with its NX-B2 Professional+ collection of Sort B playing cards. Although nonetheless within the growth stage, they’re stated to be able to a blazing-fast most learn pace of 3700MB/s, and an equally spectacular 3600MB/s peak write fee.
However what actually units B2 Professional+ playing cards other than the competitors is their VPG1600 certification. VPG (Video Efficiency Assure) is a tightly-controlled testing process and certification that ensures a reminiscence card can maintain a minimal write pace when recording video. Loads of SD and CFexpress playing cards have VPG200 or VPG400 certification, which means they’re assured to keep up a minimal 200MB/s or 400MB/s write pace, however that is the primary time we have heard of a Sort B card with the newest VPG1600 ranking. It certifies {that a} B2 Professional+ card will be capable of maintain an unimaginable 1600MB/s minimal write pace whereas recording video.
Nextorage has some historical past with pushing VPG pace limits. Again in March it revealed its A2 Professional collection of CFexpress Sort A playing cards, which had been the first-ever Sort A playing cards to obtain VPG800 (800MB/s minimal sustained write pace) certification.
Surprisingly, whether or not it’s the VPG800 Sort-A playing cards, or this newest VPG1600 B2 Professional+ Sort B card, each nonetheless sport the older VPG400 icon along with their new VPG800/1600 certification. It’s because these newest VPG pace requirements do not really exchange the older VPG200/400 scores; they as a substitute complement them. That is because of the VPG800 and 1600 scores being a part of the brand new Video Efficiency Assure Profile 5.0, launched by the CompactFlash Affiliation in February 2025. VPG-5 is not backward suitable with VPG Profile 4.0 (which covers the present VPG200 and VPG400 scores). As such, a VPG800 or 1600 card could not work with a digital camera recording mode that requires VPG200 or VPG400.
It’s because to attain the upper sustained write speeds of VPG800 and 1600, such a card should first be preconditioned (initialized) with low-level formatting. This preconditioning, which has not beforehand been vital, basically resets the cardboard to its unique manufacturing facility situation, completely deleting any earlier knowledge from the cardboard. This in flip means the cardboard is a superbly clear ‘clean slate’ which has a big, contiguous cupboard space, onto which a steady video knowledge stream might be written at excessive pace. There’s due to this fact no threat of recording pace being decreased or interrupted by the reminiscence controller needing to allocate a part of the recording to a special sector of NAND flash with a view to work round any pre-existing knowledge saved on the cardboard.
This sounds completely cheap however there is a catch: merely deleting a video from the cardboard would not recuperate the corresponding cupboard space for future VPG800 / 1600 recordings – you are restricted to no matter remaining cupboard space is left after the final preconditioning (low-level formatting). To revive the total capability of the cardboard for extra VPG800/1600 recording, it’s essential to once more carry out a preconditioning. Fortunately this process would not look like vital for common use, or for VPG400 recordings.
For extra info on these newest VPG requirements, and why preconditioning is critical, take a look at the official steerage from the CompactFlash Affiliation.
We do not but have any pricing or availability info for NX-B2PRO+ Collection playing cards; solely that they might be launched in 660GB and 1330GB capacities.
