I decided to run some HDD benchmarks on 2x 320GB Barracudas 7200.11 in RAID 0 on a new systems i built for someone. First off, the strange thing is that HD Tach and HD Tune give totally diffrent burst rates for the RAID 0 setup. Furthermore, the Random Access Times and Burst Rates are just horrible, worse than my single non-RAID 150GB Raptor and Barracuda 320GB 7200.10. Here are the results for 2x RAID 0 drives:
HD Tach
Burst Rate: 436 MB/s
Randon Access Time: 17.4ms
Average Read: 187.8 MB/s
HD Tune
Burst Rate: 89.9 MB/s
Randon Access Time: 16.6ms
Average Read: 178.3 MB/s
As you can see there is some discrepancy between the 2 benchmarks in case of Random Access Times & Avg Read, but the discrepancy between Burst Rates is humongous! 436 MB/s for HD Tach and 89 for HD Tune. I think that HD Tach is way off, 89 looks like it could be closer to the truth, but i it still very low comparing to my single drives, here are their results:
HD Tach
WD Raptor 150
Burst Rate: 133.7 MB/s
Randon Access Time: 8.9ms
Average Read: 75.3 MB/s
Barracuda 320 7200.10
Burst Rate: 134 MB/s
Randon Access Time: 13.7ms
Average Read: 59.7 MB/s
HD Tune
WD Raptor 150
Burst Rate: 116 MB/s
Randon Access Time: 8.2ms
Average Read: 67.8 MB/s
Barracuda 320 7200.10
Burst Rate: 111 MB/s
Randon Access Time: 13.5ms
Average Read: 59 MB/s
So judging by these results my single drives beat the 2 drives in RAID 0 in every test except for Avg Read, how could this be? Are these normal results?
