Exascend has announced the sale of a 512GB Nitro CFexpress Type B memory card. According to a source, it could be the first VPG400-certified card to hit the market.
Western Digital announced plans to release the world’s first VPG400 CFexpress Type B card back in May 2021. However, it does not look like those plans have been realized.
The VPG400 certification is a guarantee that when shooting video, the write speed will be at least 400 MB/s without frame loss. According to Exascend, the card offers read speeds of up to 1850 MB/s and write speeds of up to 1700 MB/s. Note that so far no, even the most advanced cameras, can not output data at such speeds, being limited to a mark of about 850 MB / s. In other words, the card has a reserve for the future.
To keep the card from overheating during long writes, the designers have made sure to cool the 3D TLC flash memory with graphene heat sinks. The card’s protection rating is IP67.
At the same time, Exascend announced a CFexpress card device that supports speeds of up to 20 Gbps, which is enough to copy the entire contents of a 512GB Nitro CFexpress Type B card to a computer in less than five minutes.
Pricing is not yet known, but the memory card and card reader are expected to be available in May.
