Product Overview
A 512GB CFexpress 4.0 Type B card for professional photographers and videographers capturing high-resolution content without interruption. Sustained write speed reaches 850MB/s, feeding continuous bursts and 4K, 6K, and 8K video. Read speed hits 3400MB/s with a compatible reader, cutting transfer times sharply.
This card sits in ProGrade's Gold series, which stresses reliability and performance. A 3-year warranty and a laser-etched serial number help verify authenticity. ProGrade also offers optional software, such as Refresh Pro and Advanced Recovery Pro, to maintain card health and recover corrupted files. Both sell separately.

Design and Build Quality
The CFexpress Type B form factor sits close in size to XQD cards. Build targets the rigors of professional use, though specific durability ratings like temperature or shock resistance are not provided. A laser-etched serial number aids anti-counterfeiting. The 3-year warranty adds peace of mind.
One design note matters: the card is backward compatible with XQD devices, but only after a firmware update. That helps anyone moving over from XQD. It does not guarantee every XQD device will support it. Check with your camera or device maker for compatibility.
Performance in Everyday Use
Sustained write speed of 850MB/s aims to stop dropped frames during high-bitrate video and keep pace with rapid bursts. Fast action and long continuous takes both fit that profile. Read speed of 3400MB/s ranks exceptionally quick, slashing the time to offload large files to a computer.
Reaching these speeds carries requirements. You must use a CFexpress 4.0 compatible reader and a host device that supports PCIe 1.4c and NVMe. Cameras limited to CFexpress 2.0 will not work, since the card is not backward compatible with that standard. Confirm CFexpress 4.0 support across your equipment before buying.
Who Should Buy It
- Users with older cameras that only support CFexpress 2.0 or XQD without firmware updates.
- Not compatible with CFexpress 2.0 devices Requires CFexpress 4.0 reader and host for full speed Optional software (Refresh Pro, Advanced Recovery Pro) sold separately Specific durability ratings not provided
