Anyone able to chime in on the approximate performance I should get with 6 EXOS 14-18tb sata drives in raid 10 with Truenas and zfs. Truenas will be run in a VM through Proxmox. The server is an Epyc 7302P and 256GB 3200 ram on a Supermicro H12SSL-NT board. The EXOS drives will be attached to an LSI 9207-8i SAS3 HBA in IT mode. My goal is to be able to sustain 2-300MB/s read and writes without stalling during large files transfers. This sound doable or do I need to stick with my 6 2.5" 4TB SSDs in raid 5 to achieve that performance?
 
Current large HDDs are specced for sustained throughput in the ~200-250 MB/s range. The system is made up of solid components all-around. I think you'll be good. The only possible hitch I can see is running TrueNAS in a VM and not bare-metal, but I think if you're passing the HBA directly to it it'll be fine.

FWIW, a couple years ago Ars Technica put out a really nice article on using fio to measure storage performance.

Okay nice, I plan to pass through the HBA all the drives will be attached to. Okay, I think I will go that route then and sell all my 4tb ssd's. I think raid 10 should give me a bit more performance also over a single drive.
