The CFexpress Type B speed race continues, and we now have a new speed king: the Nextorage B1 Pro. Boasting a maximum read speed of 1950MB/s, it narrowly beats the previous fastest Type B card, the 1900MB/s Lexar Professional Diamond Series. However it's write speed where the new Nextorage B1 Pro really stretches its legs. Whereas the Lexar card could 'only' manage a 1700MB/s write rate, the B1 Pro is capable of up to 1900MB/s - impressive stuff. Equally impressive is the B1 Pro's minimum sustained write speed of 1800MB/s, which marks a third Type B speed record, and easily earns the card VPG400 certification.
