After reading W1zzard's Agility 2 review (http://www.techpowerup.com/reviews/OCZ/Agility_2_120_GB/) I noticed some of the comments were wanting a comparison of storage controllers. That got me thinking - I only have one (SB750) but it does have 4 possible modes - IDE, RAID, AHCI (MS driver), AHCI (AMD driver). Which mode is fastest? Well I spent about an hour benchmarking so I figured I might as well post the results in case anybody else was interested. Between each benchmark run I used HDDErase to give them all a level playing field. The drive was benched as a 'spare' drive (not the OS drive) as well. For drive settings write caching is enabled, write-cache buffer flushing is turned off, and NCQ is turned on in RAID mode (via RAIDXpert). All AMD drivers came from Catalyst 10.7. I only ran each test once so I don't really know how scientific the results are but they seemed pretty consistent (especially the sequential write speed). I ran CDM and HDTach in each mode but the HDTach results were not very interesting (pretty much 230 - 250MB/sec read and 190-210MB/sec write with 260MB/sec burst in all cases). The AHCI w/ AMD driver results are kind of disappointing but everything else is pretty much as I expected. Since my drive does not support TRIM I'll probably use RAID mode but if I had a TRIM-capable drive I would probably use AHCI w/ MS driver.
