Not sure I know what the issue is but telling us how many disks, what the RPM of the disks are, and what level of RAID would probably help.
It sounds like perhaps you have a bunch of 7200RPM disks in a RAID setup where the data:parity ratio may be way out of whack(e.g. high number of data disks to parity disks), which will result in very poor write performance.
yes, ita bunch of 12 7k2 RPM disks organized as 1 hot spare, 2 parity disks, 9 data disks in a RAID 5 configuration. is 9/2 a "high ratio"?
Thanks for your help
