The Plextor M3 (256GB) Reviewby Kristian Vättö on April 5, 2012 3:05 AM EST
AS-SSD Incompressible Sequential Performance
The AS-SSD sequential benchmark uses incompressible data for all of its transfers. The result is a pretty big reduction in sequential write speed on SandForce based controllers, while other drives continue to work at roughly the same speed as with compressible data.
Plextor M3 does well in incompressible sequential speeds as well. Its incompressible sequential read speed is average in our chart, but the difference between most SATA 6Gbps SSDs is only a few percent—nobody is significantly faster here. Incompressible sequential write speed is the best we've seen on a Marvell based SSD, but the Samsung SSD 830 and OCZ Octane retain their crowns.
