The 256GB is the smallest card in Codex's Elite CFexpress 4.0 Type A range, bringing VPG800 certification to Sony's Type A cameras. It sustains writes of 900MB/s and is rated for 300TB written, twice the Excel card at this capacity.

It suits Sony's FX6, FX5 and FX2, along with the FX3, FX30, a1 II, a7S III and a7 IV. It reads and writes at up to 1,800MB/s and is VPG400 and VPG800 certified for uninterrupted 8K video and high-speed stills.

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 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.
