Lexar Professional Gold 128GB CFexpress 4.0 Type B Card

The Lexar Professional Gold CFexpress 4.0 Type B card is aimed squarely at the professional who shoots high-resolution video and stills and needs storage that can keep pace. Its headline figures are the rated read speed of up to 3600 MB/s and write speed of up to 3300 MB/s, positioning it among the faster CFexpress 4.0 options on paper. But the specification that will matter most to working shooters is the sustained write speed of up to 1000 MB/s. That sustained floor is what Lexar credits for smooth 8K RAW recording and uninterrupted high-speed burst photography, and it's the number that determines whether a long take holds together or stutters.

Construction and ownership details reinforce the professional framing. The card carries Lexar's 8 Point Protection, rated to withstand extreme temperatures, vibration, dust, drops, shocks, compression, bends, and wear, which speaks to buyers working in demanding field conditions. The 128GB capacity is a working-session size rather than an archive; it suits shooters who offload regularly. Rounding out the package, Lexar backs the card with a limited lifetime warranty and includes data recovery software, and states it has been rigorously tested for compatibility. Taken together, it's a card built less for casual use than for photographers and filmmakers who treat their storage as mission-critical.
