shazbot Posted June 30, 2008 Share Posted June 30, 2008 After doing a check on the health and performances of my comp, the program gives me a red flag for the Avg Disk Queue Lengh with a average of 2, minimum of 1 and a max of 6 I have Western Digital Caviar RE 320 Gb * 3 raid 5 (so good and fast disks) they are only 1/32 full so lots of room, the disk is defragged, all temps files are binned As you can see by my comp details I have a good setup, so why do I have such bad readings ??? any help would be helpful Link to comment https://www.neowin.net/forum/topic/646399-avg-disk-queue-length/ Share on other sites More sharing options...
McSmiggins Posted June 30, 2008 Share Posted June 30, 2008 First off, "the program"? what program? Secondly, as a rough guideline, normally average disk queue length should be less than the number of spindles in the array (so you've got 3), it'll peak higher than this however, what raid controller are you using? Fast disks on a slow controller aren't going to give you the greatest performance.

shazbot Posted June 30, 2008 Author Share Posted June 30, 2008 (edited) The program is "Information and performance tools" (sorry I running the French system, so that might be slightly wrong) it's Vista own program the raid is running off the MB and latest Nvidia drivers are installed "nforce_winvista64_15.17_international" I have thought about getting a Raid card would this make things 'much' better or could I just change the raid setup, to speed things up raid 0 for intance thanks in advance Edited June 30, 2008 by shazbot Link to comment https://www.neowin.net/forum/topic/646399-avg-disk-queue-length/#findComment-589522386 Share on other sites More sharing options...
shazbot Posted July 2, 2008 Author Share Posted July 2, 2008 Update migrated my raid 5 to raid 0 and all is just perfect I can even see the speed difference myself It seems that the MB raid setups can run raid 5, but as raid 5 are far more complicated than 0 or 1, the soft has trouble dealing with hence the loss of speed Link to comment https://www.neowin.net/forum/topic/646399-avg-disk-queue-length/#findComment-589527931 Share on other sites More sharing options...
selphj Posted July 3, 2008 Share Posted July 3, 2008 Yeah, your drive array setup was being too slow. Just realize what you've done. RAID5 has fault tolerance to deal with 1 failed drive. That means with RAID5, you can have a total drive failure and still function with no data loss across the array. RAID0 is the opposite, and will cause complete data loss of the entire array if any drive dies.

shazbot Posted July 7, 2008 Author Share Posted July 7, 2008 Yes I know that, thanks anyway I have ordered a raid card so will install it when it arrives, though this means that i have to re install vista .... and as I have and have 2 raptors not be used might try raid 1 set-up rather than the 0 But will be fun playing with it an Link to comment https://www.neowin.net/forum/topic/646399-avg-disk-queue-length/#findComment-589537414 Share on other sites More sharing options...
