{"product_id":"wise-cfexpress-4-0-type-a-memory-card","title":"Wise CFexpress 4.0 Type A Memory Card","description":"\u003cp\u003eThe 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.\u003c\/p\u003e\n\n\u003cp\u003eAvailable 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.\u003c\/p\u003e\n\n\u003cp\u003eAt 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.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eUp to 1865 MB\/s read \/ 1750 MB\/s write\u003c\/strong\u003e — PCIe Gen 4 x1, NVMe 1.4 interface, double the speed of CFexpress 2.0\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVPG400 certified\u003c\/strong\u003e — guaranteed minimum 400 MB\/s sustained write for drop-frame-free recording at any bitrate\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCFexpress Type A form factor\u003c\/strong\u003e — designed for Sony Alpha and FX cinema cameras\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAvailable in 256GB, 512GB, and 1TB\u003c\/strong\u003e — choose the capacity to match your shoot\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTLC NAND flash\u003c\/strong\u003e — reliable, consistent performance across the card's full lifecycle\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUltra-compact and lightweight\u003c\/strong\u003e — 20 x 28 x 2.8 mm, just 2 grams\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e5-year limited warranty\u003c\/strong\u003e — extendable to 6 years with free product registration\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat's in the Box\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eWise CFexpress 4.0 Type A Memory Card (selected capacity)\u003c\/li\u003e\n\u003cli\u003eQuick Start Guide\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cdetails open=\"\"\u003e\n\u003csummary\u003e\u003cstrong\u003eIs this card compatible with my Sony camera?\u003c\/strong\u003e\u003c\/summary\u003e\n\u003cp\u003eThe Wise CFX4-A series is compatible with Sony cinema cameras (FX30, FX3, FX6, FR7), Sony camcorders (PXW-Z200, HXR-NX800), and Sony mirrorless cameras (α1, α1 II, α7 IV, α7R V, α7S III, α9 III).
