Lexar Professional Silver 256GB CFexpress Type B 1750MBs Read 1300MBs Write

Designed for demanding stills and video work, the Lexar Professional Silver 256GB CFexpress Type B card delivers high sustained throughput for burst photography and large-frame video capture.

With a 256GB capacity it provides ample room for extended shooting sessions, while the high read and write performance helps keep camera buffers clear and cards ready for the next take.

Lexar lists sequential read speeds of up to 1750MB/s and sequential write speeds up to 1300MB/s, making this card well suited to tasks such as continuous high‑frame‑rate RAW capture, 4K/6K/8K video recording (where supported by the camera), and fast off‑loads to a compatible reader.

The card uses the CFexpress Type B form factor and the PCIe/NVMe interface to achieve those transfer rates, so you’ll see noticeably faster ingest times compared with UHS-II SD cards when paired with a suitable reader.

The card is built for professional workflows: Lexar states it provides resistance to temperature extremes, shock and vibration, and X‑ray exposure, helping protect your footage and images in transit or on location.

The compact CFexpress Type B design fits cameras and recorders that accept that format and will deliver the best results when used with devices that explicitly support CFexpress Type B media and high bit‑rate recording.

In practical use you’ll notice quicker buffer recovery between bursts, smoother high‑bit‑rate video recording and reduced waiting time when archiving files.

For studio tethering, fast read speeds allow quicker previews and editing directly from the card.

As with all high‑performance cards, ensure your camera firmware and external card reader support CFexpress Type B and the indicated speeds to take full advantage of the card’s capabilities.
