Glyph’s New CFexpress Type B Memory Cards

credits: Glyph

Memory and storage device manufacturer Glyph is expanding beyond external solid state drives and into camera memory with the announcement of a series of CFexpress Type B cards. It is a move we have already seen from other storage brands like OWC.

The new cards fall under the Capture+ series and are based on the newer CFexpress 4.0 standard, with capacities ranging from 256GB up to 4TB. The lowest capacity card, the 256GB, appears to be more designed to support photographers and has a sustained write speed of 550 MB/s, while the 512GB jumps to 1,100 MB/s, the 1TB to 2,100 MB/s, and the 2TB and 4TB versions go up to 3,000 MB/s. Peak speeds are listed at 3,700 MB/s read and 3,500 MB/s write across the lineup, but those are not always the most useful numbers in real-world shooting. All cards are also optimised for thermal performance inside a camera, which matters when you are shooting long bursts or high-bitrate video.

It is worth mentioning that right now no camera is capable of taking advantage of the peak read and write speeds that CFexpress 4.0 offers, as only CFexpress 2.0 is currently supported, but the cards are backward compatible, so they will still work in existing cameras. The higher bandwidth mainly helps when transferring files, where offloading large photo or video files should be noticeably quicker. The cards also include basic durability features like resistance to shock, dust, and x-rays, along with safeguards to protect data during power loss. Pricing has not been announced yet.
