Toshiba will start volume production of two new SSD modules in October; the drives are remarkable not for their storage capacity, but for their physical size. The new drives are based on their latest 32nm MLC NAND flash technology; this enables Toshiba to bring the physical size of the drives down.

The new drives are available in 30 and 62GB sizes, in both a half-slim SATA-2 and the brand-new Mini SATA-2 (mSATA) form factor. The table below shows the most important details as provided by Toshiba. The drives are several times smaller and lighter than traditional 2.5 inch drives, which makes these ideal for netbooks:
“Initial adoption of most SATA solid state drives has followed the HDD form factor. Our latest 32nm mSATA and Half-Slim case-less modules enable hardware designers to add the performance and reliability advantages of a solid state drive in a smaller, footprint for notebooks, portable electronics and other embedded storage applications,” said Scott Nelson, VP Memory, TAEC.
