rx2_007SATA RAID Disk Speeds - Is this correct???
by on May 23, 2006 at 9:25:45 am

Hi,

I have just hooked up 4 SATA 160GB Seagate drives to my motherboard's onboard RAID, and configured it as a RAID 0.

I just ran the File System Benchmark module of SiSoftware's Sandra and it gave me these results :

Benchmark Results
Drive Index : 153 MB/s
Results Interpretation : Higher index values are better.

Benchmark Breakdown
Buffered Read : 445 MB/s
Sequential Read : 202 MB/s
Random Read : 65 MB/s
Buffered Write : 395 MB/s
Sequential Write : 225 MB/s
Random Write : 105 MB/s
Average Access Time : 10 ms (estimated)

If I am reading this correctly it is saying I am getting 202 MB/s in sequential reads, and 445MB/s in buffered reads. Is this what you would expect, because my initial thoughts is these figures are a bit on the high side considering my setup????

I don't have a declink card yet so I can't run there diskspeed utility. And well I haven't quite figured out how to use IOMeter yet....

Peoples thoughts would be appreciated...

Cheers

Robert
