Lexar has announced its Diamond CFexpress Type B cards, which should be the fastest CFexpress Type B cards on the market once they start shipping. Also announced is a new set of Gold Series CFexpress Type A cards.

Lexar, now a subsidiary of Longsys, says the new CFexpress cards will hit some impressive speed marks. The Diamond Series CFexpress Type B cards have a read speed of 1,900 MB/s, the fastest on the market that come in 150 MB/s faster than Angelbird’s AV Pro cards. The Lexar cards don’t quite keep up that speed for write performance, but still promise an impressive 1,700 MB/s, which is equal to what most other CFexpress Type B cards on the market promise for peak read speeds.

The cards are VPG 400 certified, ensuring write speeds never drop below 400MB/s, making them ideal candidates for recording up to 8K Raw video internally on cameras that offer it.

Lexars’ cards are shock and vibration proof as well as resistant to extreme temperatures from 14-degrees Fahrenheit (-10-degrees Celsius) to 158-degrees Fahrenheit (70-degrees Celsius) and non-operating temperatures from -4-degrees Fahrenheit (-20-degrees Celsius) or 185-degrees Fahrenheit (85-degrees Celsius).

Lexar has also launched its CFexpress Type A Gold Series cards which promise up to 900 MB/s read speeds and 800 MB/s write speeds, making them faster than both the ProGrade Digital and Sony cards of the same design. The company plans to launch a new CFexpress Type A reader in the coming months as well.

Both Lexar’s Diamond Series CFexpress Type B cards and Gold Series CFexpress Type A cards are covered by a lifetime warranty.
