Intel has unveiled its upcoming SSD 320 series codenamed Postville Refresh, which will become the successor to its very popular X25-M SSD series.  These are due to launch mid-April.

The new 320 series will use 25nm MLC NAND and will be available in capacities of 40GB, 80GB, 160GB, 300GB and 600GB.  So far the performance figures have not been finalised, but according to VR Zone, these are rumoured to feature up to 250MB/s read and 170MB/s write, with impressive IOPS figures of up to 50,000 IOPS read and 40,000 IOPS write.

It’s worth noting that the fastest spinning hard disks are only capable of several hundred IOPS, so while these figures may not seem much better than SSDs using the SandForce SSD controller, these ratings are well ahead of what can be achieved with any RAID configuration of spinning hard disks. It will also be interesting to see how these perform in the real world.

So far no pricing information is available at this time.
