The 512GB is the smallest card in Codex's Excel CFexpress 4.0 Type B range, built into an aluminium thermal case like every Codex Type B card. It sustains writes of 1,750MB/s and is rated for 300TB 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 avoids thermal throttling as the card warms up, and 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.
