Some interesting developments!
I installed a fresh copy of Windows, and all the VIA and nVidia and
so on drivers. At some point during all this (a period of relatively
heavy disk IO), the computer seemed to crash and I rebooted it. It
then worked fine for a while, but during my perfmon testing it
seemed to do the same thing. This time I left it for a while and it
did eventually wake up again, so I'm guessing the controller is a
bit fubared. Perfmon did indeed show several dips down to or very
close to 0 during the write operation, with peaks up to 48 MB/sec,
which is pretty respectable. So, time to replace the brand-new
controller I guess.
Now, do you think this is just my one particular controller card and
a simple return would fix the problem, or is it more likely a
problem with the whole range? It's an Innovision EIO SATA
controller: http:// www.ivmm.com/eio/products/index.htm
Would it be a safer bet to go for the Adaptec controller of the same
variety? How reliable are they?
I frankly don't know. Maybe it's just one faulty controller,
connector or whatever. Maybe the card manufacturer screwed up
somewhere. I mean, the only course I took in electronics is
introductory digital circuits which used 74xx chips and push triggered
clock on a breadboard. What would I know about gigahertz signaling
error. :-p
Though, one thing I can say is majority of 311x controllers don't
seem to suffer from this problem. So, take your pick.
Right, I've replaced my previous controller with an Adaptec AHA-1205SA,
and I'm rebulding 2 RAID-1 arrays at 50MB/sec without a hitch.
Thanks for your help diagnosing my problem, it was much appreciated!
Many thanks,
Chris
