Don't get these write figures on the hard drive...

Hi,

I've got a 15K Hitachi SAS drive (HUS151414VLS300) on my Dell 690 machine. I've ran ATTO Disk Benchmark what it shows is that the write speed on small file sizes is virutally non-existant (although the read speed is fine) and on large file sizes it's normal. It's only on this drive that I seem to have these problems. I've got other SAS drives connected to the same controller and their fine. Other external/internal drives are no problems either. There is no write cache enabled biut it isn't enabled on the other drives either.

Here's a link to the results:

Would you know what mobo your Dell uses? And its specs? What about your other components?

im thinking that it may be because of the small file sizes. it doesn't have enough time to really start its max transfer speeds before the files are writen

I have a couple of other 15K SAS drives and they seem to be fine.
