Toshiba today announced a new generation of SSD modules designed for use in space-sensitive devices with high capacity storage requirements. Called These are reportedly the very same SSDs Apple uses in its new MacBook Air models so weâll likely see a new crop of ultra-slim laptops using Blade X-gale modules for storage. All models measure 24mm x 109mm. The two smaller units are just 2.2mm thick, while the 256GB model is 3.7mm. The new drives are available now to OEMs; Toshiba won't be selling these to the public - at least not initially - since systems need to be built specially for the form factor.
