Wise CFexpress 4.0 Type A Memory Card

The Wise CFexpress 4.0 Type A Memory Card (CFX4-A Series) is built for one purpose: keeping up with the most demanding Sony cinema and mirrorless cameras on the market. Whether you're shooting 8K RAW on a Sony FX6, capturing ultra-high-speed 4K bursts on the α9 III, or recording rich XAVC S-I footage on the FX3, this card delivers without flinching. With read speeds of up to 1865 MB/s and write speeds of up to 1750 MB/s over PCIe Gen 4 x1 — double the throughput of CFexpress 2.0 — you finally have a card that matches the camera, not the other way round.

Available in 256GB, 512GB, and 1TB, the CFX4-A series covers every kind of shoot. The 256GB is the working shooter's reliable second card; the 512GB is the workhorse for full-day productions; and the 1TB is for the long-form filmmaker who simply cannot afford to stop and swap cards mid-shoot. All three capacities carry the VPG400 Video Performance Guarantee, meaning a certified minimum sustained write of 400 MB/s — no dropped frames, no surprises on set. TLC NAND flash ensures consistent performance throughout the card's lifetime, not just on a fresh card.

At just 20 x 28 x 2.8 mm and weighing 2 grams, the Type A form factor is one of the most compact professional media formats available. It slots directly into the CFexpress Type A slot found across Sony's Alpha and FX lineup, with full compatibility confirmed across Sony FX30, FX3, FX6, FR7, PXW-Z200, HXR-NX800, α1, α1 II, α7 IV, α7R V, α7S III, and α9 III. All Wise memory cards come with a 5-year limited warranty, extendable to 6 years by registering your purchase within 30 days at wise-advanced.com.tw.
