Supermicro sells server-class hardware and the other brands mostly small
SOHO boxes.
Completely different performance and reliability target markets.

A Supermicro-based server with a supported RAID adapter (Areca or LSI)
and a SAS backplane should be fine. A 2U chassis can take up to 12 3.5"
hard drives (+2x 2.5" ones) and should be largely enough for 20TB.

Some 10Gb ethernet adapters are also supported if you really need NFS
transfers to be fast.
