Is that even true? Well, B&H Photo has a nice guide on the speediest memory cards, and it seems that the write speed of Sony’s latest cards do in fact beat the previous champions, which top out at 260MB/s. This is great stuff for photographers who are shooting at demanding burst modes and recording video at 4K resolution. And to complement most rigs that are usually weather sealed nowadays, these cards will be waterproof, temperature resistant, shockproof and X-Ray proof.

SD cards still can’t approach the kind of speeds CFast 2.0 and XQD cards boast, but that’s not stopping Sony from upping their SD game in a big way. Earlier today, Sony officially announced the "world’s fastest SD cards," their new SF-G series. Announced ahead of CP+, the SF-G cards come in 32GB, 64GB, and 128GB sizes and boast some blistering fast read/speeds. Specifically, these little cards can read and write photos at 300MB/s and 299MB/s respectively. As long as your camera supports UHS-II, you’ll be able to take advantage of these speeds for burst shooting, 4K video, and other buffer-busting uses.
