Speed: RAID-5 vs RAID-0

See About RAID.

When tested on a faster CPU*, the RAID-5 performance notchs to a higher level (same drives and enclosure). Write speed is up to 400 MB/sec from ~370MB/sec.

CPU speed is involved because RAID-5 must compute an XOR to generate the parity information; this is single threaded so a high Turbo Boost clock speed can really speed things up.

RAID-5 are the lower red and green lines.

RAID-5 vs 3X RAID-0 stripe vs 4X RAID-0 stripe
(SoftRAID 5 beta)

When tested on a faster CPU* with the same drives and enclosure, the RAID-5 performance notches to a higher level: read speed is similar, but write speed has risen to 400 MB/sec (below) from ~370MB/sec (above).

RAID-5 are the lower red and blue lines.
