At 1TB, CODEX's Excel CFexpress 4.0 Type B card has nearly twice the space of the 512GB card at the same 1,750MB/s sustained write, so there's longer between card changes. It's built into a full aluminium casing and rated for 600TB written.

It works with Type B cameras and recorders including Canon's EOS C400 and EOS R5 Mark II, Nikon's Z 8 and Z 9, Panasonic's LUMIX GH7, Blackmagic Design's PYXIS 6K and the Atomos Ninja TX. It reads at up to 3,750MB/s, writes at up to 3,350MB/s and is VPG400 certified for uninterrupted 8K video.

HeatControl ensures optimal and consistent performance, even in demanding thermal conditions. Every card is rated to work from −12°C to 72°C. FastLane keeps sustained writes high for continuous recording. ByteGuard pairs LDPC error correction with block-level RAID 5 to protect your footage. The card draws 1.25W at 400MB/s and 0.3W at idle, and carries a 3-year warranty when you register it, plus 2 years of data recovery. Firmware updates need a CODEX CFexpress reader.
