This machine... if you run it in raid 5 will only get 7-9 megabytes a

If you run it in RAID 10 you get a more reasonable 50-55 megabytes per
second.
I don't have it
Do you have a hw reference that runs that fast (5 x 30 = 150MB/s) ?

All,
Was that sequential reads? If so, yeah you'll get 110MB/s? How big
was the datafile size? 8MB? Yeah, you'll get 110MB/s. 2GB? No, they
can't sustain that. There are so many details missing from this test
that it's hard to have any context around it :)
I was getting about 40-50MB/s

Hmmm - a bit humbled by Luke's machinery :-), however, mine is probably

Not sure - the machines I cite are about $10K each. The machine you tested
was probably about $1500 a few years ago (my guess), and with a 5:1 ratio in
