ProGrade Digital, a new memory card company started by industry veterans, announced the first CFexpress 1.0 cards featuring capacities up to 1 TB and read and write speeds of 1,400 MB/s and 1,000 MB/s, respectively. These cards could also be compatible with XQD formats and come alongside new V90-rated SD cards.
The new CFexpress 1.0 format is the future of digital storage for high-end photography and video applications. With a theoretical limit of up to 8 GB/s thanks to support for eight channels that each run at 1 GB/s, these cards have a lot of room to grow. But that doesn't mean they're slow today. In fact, as the first public demonstration of CFexpress 1.0, these are some of the fastest cards to date — period.
While XQD is a format that may well die out with the advent of CFexpress (it may seem nearly dead already with Sony as the format's sole manufacturer), it is possible that with the right firmware, CFexpress cards could be used in XQD-accepting cameras, as the formats are potentially interchangeable. You will still be limited to the speed of the card being used, but it's possible that the transition from XQD to CFexpress could be painless. Moreover, this could easily be what other manufacturers have been waiting for before making the switch to a smaller, more capable, longer-term solution. CFexpress seems to be just that.
ProGrade's CFexpress cards will be available in 256 GB, 512 GB, and 1 TB capacities when they are released later this year around September.
ProGrade also announced V90-rated SD cards, which feature read and write speeds of 250 MB/s and 200 MB/s as well as minimum sustained write speeds of 90 MB/s for guaranteed performance for writing up to 6K and 4K video formats. The cards will ship in early May for $99.99, $189.99, and $379.99 for the 64 GB, 128 GB, and 256 GB capacities.
