CFexpress Type A has a new speed champion: Nextorage. Boasting 950MB/s maximum read and 950MB/s max write speeds, the new NX-A1PRO series are now the fastest Type A cards you can buy for Sony cameras like the a1, a7 IV and a7S III. Until now, the quickest offerings were either Lexar Gold Series or Exascend Essential Series cards, both of which could deliver maximum 900MB/s read and 800MB/s write speeds.

This makes the new Nextorage cards comfortably faster in the write speed stakes, especially as NX-A1PRO cards are also rated for a minimum continuous write speed of 850 MB/s; 150MB/s faster than any other Type A card on the market. It also means the new cards easily qualify for VPG400 certification (400 MB/s minimum guaranteed sustained write speed).
