  • Decreasing Stripe Size: As stripe size is decreased, files are broken into smaller and smaller pieces. This increases the number of drives that an average file will use to hold all the blocks containing the data of that file, theoretically increasing transfer performance, but decreasing positioning performance.

  • Increasing Stripe Size: Increasing the stripe size of the array does the opposite of decreasing it, of course. Fewer drives are required to store files of a given size, so transfer performance decreases. However, if the controller is optimized to allow it, the requirement for fewer drives allows the drives not needed for a particular access to be used for another one, improving positioning performance.




goodluck

the real equation would be like this

Min block size/# of drives in the array = stripe size

4/2=2

so 2 i guess?

every file would be interleaved with half on one drive half on the other

ok, so actually the incriments are 2, 4, 8, 16, 32, 64, 128

so i should set the chunk size at 2, or should i leave the bios on auto detect and format??
