I'm thinking of adding a NVMe drive to my FreeNAS. Do I need it, no, but it would be fun to play with. Any why, I'm trying to figure out what what specs on a drive are best suited to the way ZFS reads and writes.
My understanding of the way ZFS works is that it is usually writing data sequentially and will be reading data randomly. So this would mean that in the write category higher sequential write performance is more important than higher write IOPS. Then in the read category, IOPS are the key. More specifically, I'm comparing the performance of the 2TB versions of the Intel DC P4510 and DC P4600. If my reasoning is correct, the DC P4510 would be a better fit because it has higher sequential write, and random IOPS.
Am I on the right track or am I missing something in my line of thought?
