Sata 3Gb/s connection running at 1.5 Gb/s with new SSD installed
I just upgraded a 2006 desktop PC with a 240gb Sandisk Ultra II SSD. The system is faster in all the areas I'd hoped for, but not as fast as it could be.
The Sandisk dashboard reports that the connection is only 1.5 Gb/s, even though the motherboard (Gigabyte M55 SLI S4) supports SATA 3 Gb/s (Sata II.) The Window Experience Index rates the drive at 6.9. Meanwhile, a Crucial BX200 drive recently installed in a 2010 thin-n-light laptop, also SATA II, rates a 7.7 in WEI, and the laptop generally feels snappier than the desktop even though it is overall a slower machine.
A few points: the desktop PC's mobo does not support AHCI, just IDE. I've optimized all the settings I know of to optimize, eg turning off prefetch and defrag etc. I'm using a 10-year-old SATA cable. I didn't find any obvious BIOS setting to tweak.
Any ideas?
