Another week, another claim to the title of world's fastest CFexpress card! This time the coveted accolade goes to Wise, and its CFexpress 4.0 Type B PRO Mk-II cards. Headline speed figures are 3700MB/s read, 3600MB/s write, and 3000MB/s sustained write, making this the fastest ever type B card across the board. For comparison, the previous record-holder was Lexar's Professional CFexpress 4.0 Type B DIAMOND Series card, which topped out at 3600MB/s read and 3300MB/s write. 

The new Wise Type B card achieves these incredible speeds thanks to its ultra-fast pSLC NAND flash chips and PCIe Gen 4 x2, NVMe 1.4 interface. Two capacity options are available - 1.3TB and 660GB - both with the same speed ratings, costing US$1,799.99 and $969.99, respectively.
