ehhez mit szóltok?

"Knowing a bit more about how disk access works in operating systems, I would recommend another formula:

stripe size = cluster size / number of RAID-0'd drives

A filesystem cluster is the smallest amount of data a program can read from the disk (or write). Even if you request only a single byte, the OS will generously read in the whole cluster (4 kilobytes by default for NTFS). So, if you have two RAID-0 drives, a stripe size of 2K would make sure that you always have each drive processing the sama amount of data.

Mind you, for this to work, the stripe size has to work out exactly. Cluster and stripe sizes are always in power-of-two multiples of 512 bytes. So if you have an odd number of hard drives in RAID-0, you cannot possibly get an optimal stripe size."
