I saw once where you posted the speeds of your RAID array, what is the stripe size set to on your machine ?? 8kb,16kb,32kb,or 64kb.

Just wondering.
thanks.

Sorry...not around much on weekends...usually over the girlfriends condo.

I just went with "down the middle" approach of 64 size, after reading Anandtech's RAID writeup/comparison, seemed best for my needs.

Don't believe I ever posted the speed of it, only benchmark I've posted was 3DMark 2001, 5860.

I thought it was your Sisoft Sandra speeds I saw posted, but maybe not. I was wondering because I have mine set to a 64kb stripe and it's not performing quite as well as I want it to. I'm thinking of formatting and going to a 16kb stripe. I'm not sure if that will help or not but I might as well try it.

i would be interested to see the results of a 16K cluster size. i did the same thing (from 64K to 16K), and i get at times wildly varying results. sometimes i will have a burst/cached speed thats lower than my sustained reads (72MBps sustained and 60MBps cached, which i have seen before). with 64K, things were a little more consistant (usually 76MBps to 80MBps cached and 70 to 74 sequential).

of course there were differences between the configuration then/now such as partition size and the amount of data on the drive(s).

anyways, post 'em when you have 'em.

I'll be in Little Rock the better part of this week so I will not be have the time to format and all that fun stuff till next weekend but I will post em.

Nope, definitely wasn't me..I hate SiSoft and think their benchmarks are as useless as #$% on a bull.

I am curious to see how your stripe testing goes....never had the time to do it myself, just poured through a few writeups here and there, mostly leaned on a writeup Anandtech had over a year ago, and went with the 64 approach.

I've now been told that the onboard FastTrak 100 lite bios has a set stripe size of 64kb. I have not found out if there is a way to change it or not. I don't want to format and then not be able to change the size.
I am still looking for a definite answer.

you should be able to enter your IDE RAID controller's BIOS and see what settings there are before you actually recreate an array. just don't finalize the changes. like how you can flip through different options in your system BIOS, but as long as you dont save the changes and exit, nothing is actually changed.
