The Crucial m4 SSD Update: Faster with FW0009by Anand Lal Shimpi on August 31, 2011 12:56 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.
AS-SSD tends to post higher numbers than our Iometer sequential tests, and here we see Crucial break the 500MB/s barrier in read performance with the FW0009 update.
Write speed under AS-SSD actually fell a bit, the older firmware was 10% faster here.
