For sequential read performance, use dd. Most variants of dd I've seen
output some timing information, and if not, do a "time dd
if=/your/device of=/dev/null bs=1M" on the partition.
we had a similar problem with a hitachi san, the ams200. Their
performance group refused to admit the fact that 50mb/sec dd test was
a valid performance benchmark and needed to be addressed.

any questions?
Yes, one.
What was that unit?
