During CES 2024, Lexar announced two new 1TB CFexpress 4.0 memory cards: a Type B model in the Diamond series and a Type A model in the Gold series. The Lexar 1TB CFexpress Type B Diamond is one of the fastest memory cards in its class, with read speeds up to 3.600MB/s and write speeds of 3.300MB/s. So, let’s take a closer look at these!

The recent CFexpress 4.0 standard update was unveiled in August 2023. This new version doubles transfer speeds over its predecessor, with maximum theoretical read and write speeds for Type B memory cards up to 4GB/s.

Over the last few months, various manufacturers, including OWC and Nextorage, unveiled CFexpress 4.0 Type B memory cards. However, no camera on the market currently fully supports and takes full advantage of the new CFexpress 4.0 standard. Nonetheless, since these cards are backward compatible with previous CFexpress versions, you can benefit from the improved transfer speeds when backing up footage and also future-proof your investment.

Memory card specialist Lexar has been creating content-creator-oriented solutions for over two decades. The company is joining the CFexpress 4.0 bandwagon by announcing the Lexar CFexpress 4.0 Type B Diamond and CFexpress 4.0 Type A Gold.
