I don't believe the specs either, because they are for the "ideal" case.
However, I think that either your benchmark is flawed, or you've got a
crappy controller. I have a (I think) 5400 RPM 4.5GB IBM SCA SCSI drive in
a machine at home, and I can easily read at 7MB/sec from it under Solaris.
Linux is slower, but that's because of the drivers for the SCSI controller.
I haven't done any benchmarks on my IDE drives because I already know that
they're SLOW.
