Title: SATA Raid0 performance degradation Post by: Stephen Zepp on January 22, 2007, 02:48:19 PM About 2.5 years ago I bought an Alienware Area 51 (insert "build your own dammit!" comments here, but wasn't appropriate for me at the time), and it was pretty damned impressive for quite a long time.
Recently however I seem to be really chugging along on apps and games that have extensive disc access...from doing large SVN updates that right to disc, to almost a half to full second system freeze in some games when certain things are apparently being written to a log file, to literally 45-120 seconds of virtual memory swapout for < 2 gig of total memory. Current info: Intel 82801FR SATA RAID Controller, 10k rpm drives Driver Provider: Intel Driver Date: 3/23/2004 Driver Version: 4.0.0.6211 My question is this: Are there any debugging/troubleshooting tools out there designed to measure/tweak performance for these types of setups specifically? I did -just- realize that my free space has dropped signifigantly) and at 161m free, I'm almost guaranteed that's the issue, but it brings up the need anyway to keep a better eye on performance, so I figured I'd ask the experts out there!

I would suggest PCMark, or Sandra, and then use the hard drive analyzer. You could probably find a HD specific analyzer also with a quick search.

You may want to free up some space and defrag the drive. Also, get a SMART monitoring tool and check to see if your drives are accumulating a lot of errors. |
