I believe you have to use 128k stripping for RAID0.

I read the FAQ on this and it said the higher the better for the most part. Wasn't sure if there were some other settings to keep in mind with the Raptor. Thanks REP+

Actually, i get slow speed when i set stripe size to 128k. 64,32, and 16 work best for me

Thats not true, basically the size that you chose, whether it be 128k, 64k, 32k, etc, etc, is the size of information that is placed on each disc in the raid. As such, when you have more discs, you want a lower stripe size because all the discs will be looking for less information, it allows you to spread out the information more evenly. For two discs I would do 128k, as it will be less work for you discs with larger bits of info on each. However, say you had 3 discs and a 256k file, if you used the 128k the data would only be spread across two if the discs, which would take it longer to access it. Anyways, to much talk, go 128 or 64...

Haha figures. I'm glad I asked anyway. I just dont want to have to formatting or anything to figure out what the best perfomance is.

It depends on the file size of the programs on your HD

-For Video Editing (big files) use 128KB.
-To accelerate very small file access, such as MP3's, use a small stripe size, e.g. 16KB.
-To accelerate your operating system and for general use, I suggest 64K or 32KB.

Otherwise, you want stripes 1/2 the size of the most common files I suppose, theoretically anyway…
A way to find the average file size is to use disk defragmenter’s analysis function, and half the “average file size”.

Stripe size starts at 1KB and goes up in doubles, (1, 2, 4, 8, 16, 32, 64, 128, 256 options) for most controllers.

Edit: forgot to mention, if you use too small of a stripe size, it puts more stress on your CPU to help load the files for the HD's.

Yea these drives are strictly for OS and game files. Nothing more.

Hmm... On my uncles computer it required that you use 128k for RAID. He has a Intel G965 motherboard.

I am going to RAID0 Raptors soon. I think I will do 64k
