Posted this elsewhere too but thought I'd try this list as well.
I'm trying to understand if my RAID0 performance is typcial for an older system or if it seems slow - and if the later, if there's anything I can do about it.
Here's my system specs (relevant pieces anyway):
ASUS A8V Deluxe
(sports a Promise PDC20378 RAID controller which I'm using for my
A64 FX-60 (not overclocked)
1GB DDR PC3200
Two WD Raptor 74GB Sata150 drives in the RAID array
Win XP Pro SP2
At any rate, with Sandra i see rates of about 73MB/sec. With HD Tach I see rates between 83MB/sec and 93MB/sec, average of about 84MB/sec and burst rates of 103 MB/sec. It also shows a random access time of 8.1msec and cpu utilization of between 1 and 2 percent.
The rates seem low to me for Raptors in a raid0. Does anyone know if there are limitations with the Promise that may be the cause (or anything else on this MB)? Any suggestions for how to go about improving this
(and don't say get a new MB please!).
