Sabrent has followed up on its first-generation CFexpress Type B cards with a new set that improves transfer speeds and also doubles the previous cards’ highest capacity.
The new Sabrent Rocket CFexpress Type B memory cards promise better performance, endurance, and capacity. The company says that they reach peak read and write speeds of up to 1,800 MB/s and 1,700 MB/s with sustained speeds of up to 1,300 MB/s. The cards are also available in up to 2TB of capacity.
As a note, it’s more helpful to know the lowest sustained speed the card allows rather than the highest it can attain, so it remains to be seen if the cards will be suitable for high-end video use since Sabrent does not appear to have been granted the VPG 400 certification. That said, very few CFexpress Type B cards on the market that PetaPixel has tested showed less than the 400 MB/s sustained speeds required for that certification. PetaPixel has not tested any Sabrent cards yet, however.
“Our Rocket CFX Type B memory cards utilize dual PCIe 3.0 lanes to reach speeds of up to 1,800 MB/s for reads and 1,700 MB/s for writes to give you the fastest transfer rates possible,” the company claims. “These Rocket CFX Type B memory cards operate with SSD-grade hardware for both the controller and the flash memory. This means high endurance thanks to quality hardware and powerful wear management features such as LDPC, ECC RAID, end-to-end data protection, SmartRefresh, wear-leveling, plus support for TRIM.”
These claims are not out of the ordinary and are relatively common across the modern CFexpress Type B memory card market. Still, Sabrent does promise broad camera compatibility which means photographers should expect the cards to work for them regardless of which camera they put them in — this is slightly different than brands like Angelbird which are pretty picky about which cards pair best with specific cameras.
Of note, these cards do not appear to replace Sabrent’s previous CFexpress options that are slightly slower and don’t offer as high capacities, and are differentiated only by color (copper versus blue).
Sabrent’s new CFexpress cards come with a one-year warranty without registration and a three-year warranty with registration. The cards are currently available for pre-order from the company’s website (no confirmed shipping date has been provided) in 512GB, 1TB, and 2TB capacities for $270, $450, and $650 respectively.
