The AS SSD sequential benchmark, which uses incompressible data for all of its transfers, illustrates performance nicely. Controllers that use on-the-fly compression for example will show big drop in sequential write speed when handling incompressible data.

In AS SSD benchmark the situation is pretty much the same and although Corsair’s Neutron GTX squeezes some impressive performance OCZ Vector simply has superior maximum performance both in read and write scenarios.

CrystalDiskMark 3.0.2 confirms what we had a chance to see previously in the AS SSD benchmark, as we only had some trouble with the 4K QD32 write performance but with such impressive results across the board it is obvious that OCZ/Indilinx Barefoot 3 controller does an incredible job.
