advice with hardware configuration

If you plan to scale up in the future you could consider the following config to start with:

Pool size=2
3 x servers with OS+journal on 1 ssd, 3 journal ssds, 4 x 900 gb data disks.
It will get you 5+ TB capacity and you will be able to increase pool size to 3 at some point in time.
