I'm considering combining all my flash (VM storage) and spinners (media storage) into a single FreeNAS box. I'd go with 2 pools (one for flash, one for spinners) as I don't want to risk the failure of either vdev(s) taking out all data. I'm sure one of the most annoying things is when users come on this forum and complain about the performance of their FreeNAS servers not meeting their expectations. So for the sake of trying to avoid that situation, I'm here to have my expectations set realistically.
Given the following hardware and proposed configuration, what kind of read/write speeds can I expect from each pool.
Server Hardware:
Xeon D-1518 (4-core/8-thread) w/onboard LSI2116 HBA
64GB DDR4 RAM
Dual 10Gb NICs, Dual 1Gb NICs
Pool #1: RAID10
Hitachi HUSSL400 400GB SAS SSDs (x4)
WD Gold 10TB (x4)
