CODEX's largest Excel CFexpress 4.0 Type A card, the 1TB, sustains writes of 1,650MB/s, nearly twice the smaller cards, for long high-bitrate takes on Sony's Type A cameras. It's rated for 600TB written.

It suits Sony's FX6, FX5 and FX2, along with the FX3, FX30, a1, a1 II, a9 III, a7S III, a7 IV, a7 V and a7R V. It reads at up to 1,800MB/s, writes at up to 1,650MB/s and is VPG400 certified for uninterrupted 8K video, moving between video and burst stills on the same card.

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 2.8W working and 0.5W at idle, which is easy on camera batteries, and carries a 3-year warranty when you register it, plus 2 years of data recovery.
