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.

We are looking into adding some new disks to our server with server attached storage. One of the solutions we are considering is this <https://www.dell.com/en-us/shop/768tb-ssd-vsas-read-intensive-sed-512e-25in-hot-plug/apd/345-bcdn/storage-drives-media#techspecs_section>. The page talks about Data Transfer rate but I am interested in the IOPS, we have the IOPS info for the older disks. Does anyone know how to get the IOPS (read, write, .. any) for those disks
