How to get the most random write & read performance?

Hello all, thought this might be a good place for this kind of question.

I’m trying to find a solution for increasing my random read & write performance inside of a windows 10 virtual machine. This virtual machine will be a host for 7 other Windows 10 clients to connect to for a proprietary program. I’m not set on any particular host OS (currently using UnRaid, but playing around with Proxmox on a test machine). It’s for a production machine so I’d like for the vm to be stored onto a RAID array (I know RAID is not a backup) of some kind to prevent downtime for the business in the event a drive dies (currently using 2 mirrored samsung SATA-III SSD’s with XFS as the filesystem, heard bad things about BTRFS when I initially created it). Any advice on hosts, filesystems, or general configuration guidance? Thanks in advance!

For context using CrystalDiskMark8 with 1GB test size my RND4K Q1T1 Read: 23.81MB/s Write: 21.42MB/s.

use Promox with ZFS and get rid of consumer SSDs.

Any particular recommendation for a particular drive that has good random read & write performance? Haven’t played around with enterprise SSD’s before.

How good? In terms of non-RAM media, Optane is the very pinnacle of random I/O performance. Tape drives are at the bottom.

if you still get Optane then yes it’s definitely the best option, if not then look for KIOXIA or Solidigm.
But I doubt whether Optane are actually necessary, 7 clients is not very much.
Get four KOXIA that fit in size and make a RAID10 zpool, test which record size best suits your application and you should be good
