Toshiba Corp has started to mass production on solid state drives (SSDs) with 512GB capacity. The drives are currently only available inside Toshiba’s own notebook and the company has reduced originally declared performance figures.

Toshiba’s 512GB SSDs are based on 43nm NAND multi-level cell flash and are currently highest-capacity 2.5” solid-state drives. Toshiba now declares up to 230MB/s sequential read speed and up to 180MB/s sequential write speed for the new family of solid state drives, which is below originally declared performance figures, but which is still very high performance compared to competing devices.
