AS SSD is a benchmark that uses non-compressible and completely random data. What this means is that the drives using the 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 don't gain an upper hand.
The new Intel SSD 335 Series began brightly, posting some very promising numbers. Generally, its performance was almost on a par with the SSD 520 Series, losing out slightly only on 4k read and write speeds. Overall, despite its mainstream positioning, it had no problems matching the rest of the high-end drives.
