|
|
I'm doing some research here to verify if my RAID array is healthy. I have 2x Maxtor 80GB ATA133 7,200RPM Hard disks in RAID-0 running on a HighPoint 454 PCI Raid Controller.
Today I ran HDTach 3.0
Company site: http://www.simplisoftware.com/Public/index.php?request=HdTach# (Scroll down to DOWNLOAD)
Here are my results:
- Random Access Time: 16.6ms
- CPU Utilization: 7% (+/- 2%)
- Average Read: 80.7MB/s
- Burst Speed: 111.5MB/s
Question is, should I be concerned about the crappy access time? Single drivers get ~13.9ms w/2% CPU Utilization but an average read of only 45.3MB/s.
Tell me your setup and the results you get!

With two 120 seagate sata 8mb catch I have, 12.8ms random access, 24% CPU utilization, average read 52.7 and burst of 101.2. Used on the onboard sata, so... mine sucks
