The Intel Solid State Drive 320 Series, codenamed 'Postville Refresh', is the long-awaited successor to the present mainstream X25-M. The new SSDs are set to launch in mid-April.

Codenamed 'Postville Refresh', the Intel Solid State Drive 320 Series is the long-awaited successor to the highly popular mainstream X25-M solid state drive (SSD).

Slated for a mid-April launch, the 2.5-inch 9.5mm 320 Series will use 25nm MLC NAND and is available in five capacities: 40GB, 80GB, 160GB, 300GB and 600GB.

The 320 Series will be pushed as 'the fast hard drive alternative' with performance and data reliability as two key focus areas.

Final performance figures and drive lifespan are not available yet, but we do expect them to be pretty much the same as rumored specifications so far:

  • 250MB/sec read, 170MB/sec write
  • Up to 50K and 40K IOPS for random 4KB read and write respectively
  • 30TB to 60TB worth of 4KB random writes
