You may be able to get 160 MB/s **burst** rates under absolutely perfect
conditions. What everybody should be talking about are effective sustainable
transfer rates w/o caching. Just run for example "hdparm -tT /dev/sda" and
see what you get or run one of the benchmarks such as bonnie++.

You mean even if that disk array contained only 1 disk, it would give a
w/r flux of 160 MB/s?

Naively, I was under the impression that only because of striping that
Gb/s flux could be achieved, but you say that a single disk can w/r
with 160 MB/s?

Sorry for my naive questions.
