[Ryan Goff]

What kind of results do you see from this 3rd party utility?

Hi,
Read speeds attached. I have tested another utility too which tests write speed.

[Ryan Goff]

you're read performance looks ok, but your write performance looks to be a bit low

[Ryan Goff]

in device manager,

click plus next to disk drives
double click the drive there
click policy tab
enable write caching

see if that changes your write performance and let us know

Hi,
Enabled but didn't make any difference to write speed. I don't know what to do about this as our production slq 2000 server performs regular transaction log dumps and daily database dumps to a different server (all suffering with slow writes) which in turn takes forever to copy (1GB switch).
Thanks for your help so far.

I did some research on a proper benchmark tool. Some sites seem to find IOMeter as a good one to try:

I found a performance document regarding 6i controllers and benchmark taken from IOMeter you might be able to compare to. But obviously this is 6i, not 6402:

Thanks Ryan, I'll try it now.
I really appreciate the time you've spent helping me with this.

You're welcome!

I'm just as curious as you are for the answer to this :)
