RAID Stripe Size

[ohnnyj]

Alrighty, so my A8N-SLI has this NVRAID utility that you use to setup the RAID and at one point it asks for a stripe size. According to the manual a 128kb size should be used for performance and a 8/16 for low usage. Is this correct? From searching this site I have found that many are using a 16kb. Which should give better performance for games/photo editing/web development?

Thanks.

In the end it doesn't make much difference.

My card defaults to 64KB, so that's what I used. Basically if you are working with larger files, use a larger stripe size. Small files, small stripe size. Also remember that writing a 1KB file with a 64KB stripe size still uses up 64KB. This is why large stripe sizes (I think my RAID card goes up to 2048KB stripe size) are not good either.

In todays world, you're probably using large files mostly. So 64KB or 128KB or even higher may be best. Although with web dev, you may be using a lot of small files. Just remember what I said first.

You're confusing stripe size with inode size. They're related, but not equal.

I'd go with 16k myself, it seems a good balance between small and large. The only real way to determine which is best is to try both. Also keep in mind that the drivers might (for some reason) be buggy at one stripe size. That's no good.

I don't think so
