Hard drive performance (WD740)
I just build a pretty sweet machine and am having a tough time understanding why my HDD isn't performing up to snuff.
Asus P5Ad2-E Premium
P4 3ghz Prescott 530 800mgz fsb
2 WD740 SATA/150, 10k rpm, HDD's (RAID 0)
3 gb ram ocz pc4300
My problem is when I run a File System Benchmark test using SisSoftware Sandra I'm consistantly slower than what I should be. It's telling me my Drive Index is 80MB/s, yet a RAID 0 Maxtor 7200 rpm Drive Index is 84MB/s.
HD Tach tells me my drives are running at 110MB/s, yet a SATA 150 should be running at 150MB/s.
Does a HDD get slower as you install more programs?? I wouldn't think so. I've been using this system for about a week and I can't figure out why it's not running at top performance. My power supply is 400 watts (which should be enough), I've closed all programs, the RAID 0 is setup correctly and I just defraged.
Does anyone have any ideas?
Thanks in advance.
