Compared to the throughput of an individual hard drive, all RAID arrays provide several times more transfer performance. It is obvious that larger stripe sizes provide more performance in RAID 0, 5 or 6. The maximum difference is 35 MB/s, which equals more than 10% increase just by selecting a different stripe size!
