AS SSD is a benchmark that uses non-compressible and completely random data. What this means is that the drives using the SandForce SF-2281 controller cannot compress the data first, which takes away one of the strong advantages of this controller. Therefore this is a useful benchmark because drives that use the SF-2281 controller don't gain an upper hand.
On the copy benchmark, we found that the Seagate 600’s transfer speeds put it in the middle of the pack. The Corsair Neutron GTX, Samsung SSD 840 Pro and Plextor M5 Pro Extreme were clearly the fastest drives in this test. Rounding up the pack were the two SandForce drives - Intel and SanDisk.
On the rest of the workloads, the Seagate 600 managed to keep pace with the Corsair Neutron GTX, which meant that its overall performance was good. The Corsair Neutron GTX however still bested it at certain tests. Even so, along with the Samsung SSD 840 Pro, the Seagate and Corsair drives were some of the best performing drives.
