They are wrong. The only way to get this is by doing a block transfer
test. You could use bonnie++ or a time transfer of something more than
twice as big as your memory. I'd use bonnie++ though. Then you get
reads, writes, etc.


Thanks! But how does one go about buying a disk? I looked at some SAS disk
spec sheets on the web and they only have seek times and latency.

If I have a requirement in mind how do I evaluate what this particular disk
can or cannot generate for IOPS and MB/sec?
