Windows 7 Assesment Scoring Failure for RAID0 ?
Hello :),
I recently purchased 2 x HDD Western Digital Caviar Black EX, 640GB, 7200rpm, 64MB, SATA 3 (WD6402AAEX) and put them in RAID0.
I've installed Windows 7 x64 and HDD's connected with SATA III cable and enabled from BIOS (rest of the system is not important but for whom wants to know is: Motherboard: Asus M4A89TD-PRO-USB3, Proc: AMD Phenom II 1050T, RAM:Corsair 2 x 2 Gb-DDR3-1600MHz CMX4GX3M2A1600C8).
I have installed all motherboard drivers ofc after installing fresh Win 7 x64, and run the Windows Assesment Benchmark.
Surprise: all components went up to 7.4 but HDD's only got 5.9 Scoring .
Hmm, I ran the HD Tune Benchmark to see what's wrong with my HDD's. Nothing wrong with them, the benchmark results were these:
Transfer rate:
min: 112.1 MB/sec,
max: 203.2 MB/sec,
Average: 166.6 MB/sec.,
Access Time: 11.1 ms,
Burst Rate: 132.8 MB/sec.
I said ok. Let's change the HDD. I've took another HDD for comparison. Same company Western Digital WD3200AAKS 320 Gb. I've put is on SATA II full speed 3.0 Gb/sec normal SATA mode (not RAID). Reinstalled the above system, as well all drivers installed, then re-run the Windows Assesment Benchmark.
Surprise again: all other components had the same 7.4 score, the new HDD WD3200AAKS again, same score: 5.9. I said, something must be wrong. I re-ran the HD Tune Benchmark to make sure these are accurate values, and I got:
Transfer rate:
min: 43.2 MB/sec,
max: 108.6 MB/sec,
Average: 86.5 MB/sec.,
Access Time: 15.5 ms,
Burst Rate: 136.7 MB/sec.
Normal values, almost half of the RAID0 configuration. Still, Windows sees both HDD configurations as having same scoring. Why is that?
Thanks in advance,
