Today I've re-installed my system, and I have problems with low performance of my primary harddrives
I have an ASUS P6T Deluxe motherboard with internal SAS Raid controller.
To this I today attached 2x Intel Prescott (34nm) 80GB MLC SSD drives into Raid1 to have high performance on the volume
Before I was running the system on only 1 Intel SSD drive connected to the internal SATA controller
The problem is, that while the drive being attached to SATA controller as a single drive the windows performance index was 7.8
Now with 2 SSD drives connected to SAS controller in Raid1 the performance index dropped to 7.4
my question is - why?
Is it due lower performance of the controller?
The index dropped due lower writing speeds as due Raid1?
It's low because the drives were only quick-inited ?
I don't get it simply I really don't
I'm going to do some tests with hdparm now and hopefully I'll get to the 300MB/s read mark. If not, then it's seriously stupid
PS: the rest of the system ain't the bottleneck (i7 920, 12GB Ram, SLI/GTX285), all firmware on both MB and SAS controllers are up-to-date + the index WAS higher
