With read speeds up to 3500 MB\/s and write speeds up to 3000 MB\/s over a PCIe Gen 4 x2 interface, it's the fastest CFexpress Type B card on the market and the right match for the cameras that demand it most: Nikon Z9, Canon EOS R5, Blackmagic URSA Cine, Fujifilm GFX100 II, and more. When you're capturing 12K RAW on a Blackmagic URSA Cine or shooting continuous bursts on a Nikon Z9, this card keeps pace — every frame, every time.\u003c\/p\u003e\n\n\u003cp\u003eAvailable in 512GB, 1TB, 2TB, and 4TB, the CFX4-B series scales with your workflow. The 512GB and 1TB carry a certified minimum write of 800 MB\/s and 1500 MB\/s respectively, while the 2TB and 4TB push to a guaranteed 2400 MB\/s sustained — all backed by the VPG400 Video Performance Guarantee. TLC NAND flash ensures performance holds up over thousands of write cycles, not just on day one. At 29.6 x 38.5 x 3.8 mm and just 10 grams, it carries all this performance in the same compact footprint you'd expect from a professional CFexpress card.\u003c\/p\u003e\n\n\u003cp\u003eThe CFX4-B is compatible with a wide range of professional cameras across Blackmagic, Canon, Fujifilm, Nikon, Panasonic, RED, and Sony (BURANO), making it the one card that works across a multi-camera production.

Type B is the larger card used in cameras from Nikon, Canon, Fujifilm, Blackmagic, Panasonic, RED, and Sony BURANO. Type A is the smaller format, used exclusively in Sony Alpha and FX cameras.

VPG400 means the card is certified to sustain a minimum write speed of 400 MB\/s continuously — but the CFX4-B Series far exceeds this baseline. Certified minimum sustained write speeds are: 800 MB\/s for the 512GB, 1500 MB\/s for the 1TB, and 2400 MB\/s for both the 2TB and 4TB. This matters for professional video recording — it guarantees no dropped frames even at the highest recording bitrates.\u003c\/p\u003e\n\u003c\/details\u003e\n\n\u003cdetails\u003e\n\u003csummary\u003e\u003cstrong\u003eWhich capacity should I choose?\u003c\/strong\u003e\u003c\/summary\u003e\n\u003cp\u003eThe 512GB is a solid choice for shooters who rotate cards regularly or work in controlled production environments. The 1TB is the best all-round choice for a full day of high-resolution recording. The 2TB suits documentary and long-form filmmakers who need to minimise swaps, while the 4TB is for extended productions, multi-camera workflows, or anyone using the card as primary on-set storage. The 2TB and 4TB models also offer higher minimum sustained write speeds (2400 MB\/s), making them better suited for the highest-bitrate shooting modes on demanding cameras like the Blackmagic URSA Cine 12K LF.\u003c\/p\u003e\n\u003c\/details\u003e\n\n\u003ch5\u003eSpecifications\u003c\/h5\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eModel\u003c\/th\u003e\n\u003ctd\u003eCFX4-B512 (512GB) \/ CFX4-B1024 (1TB) \/ CFX4-B2048M2 (2TB) \/ CFX4-B4096M2 (4TB)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eForm Factor\u003c\/th\u003e\n\u003ctd\u003eCFexpress Type B\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eInterface\u003c\/th\u003e\n\u003ctd\u003ePCIe Gen 4 x2, NVMe 1.4\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMaximum Read Speed\u003c\/th\u003e\n\u003ctd\u003e3400 MB\/s (512GB \/ 1TB) \/ 3500 MB\/s (2TB \/ 4TB)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMaximum Write Speed\u003c\/th\u003e\n\u003ctd\u003e2600 MB\/s (512GB \/ 1TB) \/ 3000 MB\/s (2TB \/ 4TB)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMinimum Write Speed (VPG)\u003c\/th\u003e\n\u003ctd\u003e800 MB\/s (512GB) \/ 1500 MB\/s (1TB) \/ 2400 MB\/s (2TB \/ 4TB)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eVideo Performance Guarantee\u003c\/th\u003e\n\u003ctd\u003eVPG400\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eNAND Flash Type\u003c\/th\u003e\n\u003ctd\u003eTLC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eDimensions\u003c\/th\u003e\n\u003ctd\u003e29.6 x 38.5 x 3.8 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWeight\u003c\/th\u003e\n\u003ctd\u003e10 g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eOperating Temperature\u003c\/th\u003e\n\u003ctd\u003e-12°C to 72°C (10°F to 162°F)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eStorage Temperature\u003c\/th\u003e\n\u003ctd\u003e-25°C to 85°C (-13°F to 185°F)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWarranty\u003c\/th\u003e\n\u003ctd\u003e5-year limited warranty (extendable to 6 years with free registration)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCountry of Origin\u003c\/th\u003e\n\u003ctd\u003eTaiwan\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch5\u003eCompatibility\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eBlackmagic Design\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eBlackmagic Cinema Camera 6K — 512GB, 1TB\u003c\/li\u003e\n\u003cli\u003eBlackmagic PYXIS 6K — 512GB, 1TB\u003c\/li\u003e\n\u003cli\u003eBlackmagic URSA Cine 12K LF — 1TB, 2TB, 4TB (for 840 MB\/s recording mode)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eCanon Cinema\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eCanon EOS C300 Mk III — all capacities*\u003c\/li\u003e\n\u003cli\u003eCanon EOS C400 — all capacities*\u003c\/li\u003e\n\u003cli\u003eCanon EOS C500 Mk II — all capacities*\u003c\/li\u003e\n\u003cli\u003eCanon EOS R5 C — all capacities*\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eCanon Mirrorless\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eCanon EOS R1 — all capacities*\u003c\/li\u003e\n\u003cli\u003eCanon EOS R3 — all capacities*\u003c\/li\u003e\n\u003cli\u003eCanon EOS R5 — all capacities*\u003c\/li\u003e\n\u003cli\u003eCanon EOS R5 Mk II — all capacities*\u003c\/li\u003e\n\u003cli\u003eCanon EOS 1D-X Mk III — all capacities*\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cem\u003e* The 4TB model functions as 2TB on some Canon cameras.
