CFexpress™ 4.0
CFexpress Type B Memory Card
1024 GB｜512 GB｜256 GB
A CFexpress 4.0-COMPATIBLE MODEL FOR BOTH STILL IMAGES AND VIDEO RECORDING
The NX-B3SE series is equipped with TLC NAND flash memory and supports the latest CFexpress 4.0 standard. This CFexpress Type B memory card is ideal for still image capture, including continuous shooting using the camera buffer, as well as high-quality video recording up to 8K 30fps¹
BEST-IN-CLASS TRANSFER SPEEDS
The NX-B3SE series has best-in-class speeds, offering a max. read speed of 3,900 MB/s¹ and a max. write speed of 3,500 MB/s¹.
With high-speed data transfer, pairing it with a CFexpress 4.0-compatible card reader (NX-SB1PRO) and a USB 40Gbps external SSD (NX-PS1PRO) can significantly reduce the time required to ingest large amounts of data.
CFexpress 2.0 COMPATIBLE
The CFexpress 4.0 standard is backward compatible with CFexpress 2.0, allowing you to use it safely with CFexpress 2.0-compatible host devices. Just like the previous NX-B1PRO and NX-B2SE series, it enables stable continuous still image capture and high-quality video recording.
*NX-B3SE transfers data with CFexpress 2.0 for non-CFexpress 4.0 devices.
