Lexar Professional CFexpress Type B Gold Series

£90-£529/$100-$520

The Lexar Gold Series CFexpress Type B cards feature a PCIe Gen3x2 interface that plays a part in enabling the fast data transfer speeds. While the max read speed of 1750MB/s is up there with the recent CFexpress cards, the max write speed of 1000MB/s is behind some other offerings.

We tested a 512GB Lexar Gold Series CFexpress Type B card in the Nikon Z 9 and Z 7II. It pushed easily into the card slots, and pops up promptly after being pressed to release.

Shooting with the Type B card in our Nikon Z 7II, we captured 146 Fine-quality jpegs at 10fps, and 46 14-bit compressed raws in around five seconds. Nikon quotes a max of 113 large Fine-quality jpegs and 48 Uncompressed 14-bit raws.

The Gold Series CFexpress Type B card also proved capable of recording 4K 60p footage for 30 minutes. As we had the Z 9 in for testing, we were verified that the Lexar card can capture 8K ProRes video at 30p.

We got a read speed of 908MB/s and a write speed of 870MB/s in testing. The figures are impressive, but behind the claimed maximum figures. In another real-world test, it takes less than 33 seconds to transfer 100 raw files and 100 jpegs shot on the Nikon Z 7II from the card to our computer when using the Lexar Professional CFexpress USB 3.2 Gen 2x2 card reader.

At less than £100/$100, the 64GB Lexar Professional CFexpress Type B Gold Series card offers great value for money, while the 512GB card is one of the most affordable cards of its type.
