Hello,

unfortunately, the information is somewhat vague; we would need to know at least which MSA model (Gen6 or Gen7), iSCSI or FC, what speed is connected, what RAID level, what block size, and the read/write ratio.

Let's assume the following is typical:
MSA Gen7 with 16GB Fibre Channel, RAID 6, 8k block size, 70% read, then that should be around 100,000 IOPS.

Either way, as you can see, the MSA with SSDs is so incredibly fast that there are no performance issues in almost any configuration. (My personal experience)

Another personal tip:
There are cheap 6-Drive SSD bundles available; it's better to get two of them and then configure with RAID DP+. This offers greater reliability, faster rebuilds, and, above all, easy capacity expansion later on.

@CraigSchletty
@Cali is correct in that the question is not the right one. As the host has no direct access to the drive, the individual drive performance is not the whole story.
A great place to find performance expectations is with the MSA Sizer: https://ninjaonline.ext.hpe.com/
You can use the MANUAL mode to configure the tool with the hardware you have on hand or are planning and see the expected performance.
