Re: Data Transfer vs IOPS

As a metric for comparisons, IOPS are useless without I/O request size (or "block size").

For example, comparing 20000 IOPS for one disk means nothing in comparison to 10000 IOPS on another disk, unless you know the I/O request sizes used.

In contrast, throughput (a.k.a. data transfer rate) is a comparative metric by itself, which is probably why Dell uses it.
