The new Corsair Force GS series come in four sizes, 180GB, 240GB, 360GB, 480GB.  All are SATA 6Gbps drives and powered by the Sandforce 2200 controller but there are differences in speed because of the different sizes of drive, though perhaps not in the breakdown you would expect.  The smaller 180GB and 240GB models sport specifications of:

  • Max Sequential R/W (ATTO): 555 MB/s sequential read
  • 525 MB/s sequential write
  • Max Random 4k Write (IOMeter 08): 90k IOPS (4k aligned)

The two larger drives have slightly slower listed random write speeds, with the 360GB having slightly improved sequential writes:

  • Max Sequential R/W (ATTO): 555 MB/s sequential read
  • 530 MB/s sequential write
  • Max Random 4k Write (IOMeter 08): 50k IOPS (4k aligned)

Finally the largest 480GB model is slower at everything:

  • Max Sequential R/W (ATTO): 540 MB/s sequential read
  • 455 MB/s sequential write
  • Max Random 4k Write (IOMeter 08): 50k IOPS (4k aligned)

You can head over to Corsair and see the drives yourself.  If you are looking to purchase the drives their MRSPs are $189.99 for 180GB, $239.99 for 240GB, $349.99 for 340GB and $489.99 for 480GB capacities, meeting the ~$1/GB we all like to see.
