Not true. You might want to re-evaluate the benchmarks.
RAID-0 strip gives almost 100% speed improvement for each drive in the
strip set. There is no fault tolerance.
RAID-5 is for security not performance, it can handle a single drive
failure. In most cases you only see a moderate improvement in performance
due to the large striping size. In random access it will perform worse
than a single drive. RAID-3 improves on that by using a byte level strip
but has it's own set of drawbacks such as a dedicated parity drive.
If you don't mind a pop-up ad or 2 you can compare the different RAID
categories here.
