Intel is expanding its X25-M 2.5-inch and X18-M 1.8-inch SATA solid-state drive (SSD) family with a 160GB drive in a 2.5-inch form factor.

The X25-M product is shipping now, and the 1.8-inch 160GB version shipping next month.

Intel announced the 80GB X25-M and X18-M - its first foray into the SSD market - at its Developers Forum in August and shortly after announced the X25-E for enterprise servers and workstations. The 32GB Intel X25-E Extreme SATA is based on Intel's single-level cell NAND flash memory and is designed to maximise the input/output operations per second, while the X25M is a multi-level cell memory affording it greater capacity.

The 80 X25-M was reviewed by our sister title, Computerworld in September and was assessed as the fastest consumer-grade SSD on the market.

Intel did not immediately offer pricing on the new 160GB X25-M and X18-M drives.
