RAID 0. See posts above.

If I was to drive to NY to thank you, you better have a pair of 36DDs and a shaved kitty...and I don't mean the Garfield kind.

Yeah, thanks!

I'm gonna' be setting up some RAID arrays on my rig before too long. This is pretty much what I was looking for.

Thanks again!

So i'm still a little confused at what stripe size is best for Games. I play Everquest 2, and games like Quake 4, Fear, Need For Speed Underground etc... so Do i want to go with 4kb? Sometimes it looks like it should be higher....

Lightbulb Re: My Raid guide, and nitty gritty of strip sizes

This is an amazing plethora of information you have provided.

So I took a lot of your advice and tried different things. Here are some conclusions to I have reached.

THIS ONLY APPLIES TO RAID 5 and RAID 0 on MS Server 2003:

Just about everything you said seems very accurate. I have some data that changes when the raid is comprised of 8 drives or more. with 6 drives or below, the stripe sizes seem indeed accurate in your reccomendation.

Conclusions on 8 (750GB each) raid 5 array:

Optimal stripe size = 32

Why: with 8 drives regurgitating info to the controller, the 64 stripe size made the array move slower. If every drive has an individual read/write light, you can actually see the wave of lights like a pulse as it flows up and down the array. Seems it should be faster.

If I did a size of 16, the reads and writes did not seem as fast as ther 64 size, but also had a lot of drive activity for hardly any transactions.

Stripe of 32 rendered higher scores than 64, 16, 8 and 4 in terms of loading doom 3 levels and oblivion, it also showed faster in Sandra. But a size of 4 or 16 also made the OS perferm slower.

Incidently, the lights for the drives have less "empty" moments in 32 strip sizes.

So, upon reflection, with a hardware controller, the more drives you have in an array RAID 5 or 0, the lower the strip size for performance?
If you think of it terms of burst data, the hypothosis makes sense.

Once again, this humble opinion, ONLY APPLIES TO RAID 5 and RAID 0 on MS Server 2003

Strangly enough I changed my cluster size to 1KB and I got terrible performance from windows/applications and games... might have been the controller was incapable of handling such small sizes so I went to 4KB and all is fine, games run super smooth. Although, HD Tach reports this performance:

26.1MB/s transfer rate, 11% CPU usage, and 14.9ms random access. Is this normal? I have two pretty old Western Digital Raptors (80GB) on an ITE IT8212 PATA RAID controller.

Default Re: My Raid guide, and nitty gritty of strip sizes

Ty man just setup my first raid a raid0 but i see it as this, a single drive fails you lost your data, a raid 0 fails you lost your data lol. But thanks for the guide, is there going to be any issues with me using a Westerndigital and a seagate drive, both are 7200 RPM 500gb drives with 16mb Caches. Its in raid right now with no problems and is faster than just my western digital by itself. Never dealt with raid before, none of the PC's ive ever worked on had it lol.
