Nextorage Unveils Dual-VPG CFexpress Cards
Nextorage has outlined its latest development in CFexpress storage with the introduction of the NX-B2PRO+ series, a line of Type B cards designed to meet both current and emerging Video Performance Guarantee (VPG) requirements. The cards indeed are the first to carry simultaneous VPG400 and VPG1600 certification, a combination that until now had been considered incompatible. VPG ratings serve as a formal guarantee of sustained write performance, verified through CompactFlash Association (CFA) testing, and they allow cameras to confirm whether a card can maintain the throughput necessary for demanding video modes.
The newer VPG800 and VPG1600 classes belong to the CFA’s Profile 5.0 specification and are not backward compatible with the older VPG200 and VPG400 standards. As a result, previous cards certified for VPG1600 could not be used in modes requiring VPG400, and vice versa. Nextorage’s firmware-level implementation resolves this by making both profiles available to a single device.
According to the CFA’s certification records, the NX-B2PRO+ cards are the first to merge these ratings in one product, allowing them to function with older camera modes while also supporting sustained write speeds of 1,600 MB/s for next-generation workflows. The approach contrasts with other forthcoming VPG1600 cards, such as those from Exascend, which do not include backward compatibility. The Japanese company has previously pushed VPG thresholds with its Type A cards, which were the first to receive VPG800 certification, and it has now extended this work to CFexpress Type B.
The cards are still in development, but Nextorage reports peak read speeds of up to 3,700 MB/s and peak write speeds of up to 3,600 MB/s, figures that approach the practical limits of the CFexpress 4.0 standard. Because VPG classifications rely on firmware coding rather than marketing claims, compliant cameras can verify both supported modes. This is relevant given past incidents of manufacturers misusing VPG logos without certification, an issue that prompted the CFA to maintain a publicly searchable database of approved products.
The introduction of VPG1600 also brings operational constraints. To achieve the required sustained write speeds, cards must be preconditioned through low-level formatting, which restores a fully contiguous storage area. Deleting files alone does not recover this space for high-speed recording: the preconditioning process must be repeated to regain full capacity. These limits apply only to the VPG800 and VPG1600 profiles and do not affect general use or VPG400 recording.
Sample capacities for the NX-B2PRO+ series include 660 GB and 1,330 GB, with commercial availability planned for 2026. Pricing has not been disclosed yet.
