I would be interested to see how you go and get some iperf data on here with the Rock64. https://iperf.fr/
These have 12v input for 3.5" £10 4 or 2?
https://www.amazon.co.uk/Inateck-Adapter...B074M1G9KD
Dunno if you are going to go Jbod, RAID0, 1 or 10 (5 is sort of not good anymore)
Raid10 obviously 4 disk.
With 2 then these are only £30 https://www.amazon.co.uk/HDD-USB-RAID-En...B071HQXGWH
With 4 then seen them for about £150 https://www.amazon.co.uk/gp/product/B009O73WA0
With USB2.0 you are going to bottleneck practically any single disk.
But you could squeeze a Gig ethernet and either a RAID unit or the above singular adapters on the USB3.0.
Its extremely tight as near the max of 5Gb/s with 4 disks.
I am not sure how those cheap RAID controllers work and if they will offload the mirroring and striping needs.
*When you do port aggregation with a managed switch from memory you only get 50% effective so 2 gig ethernet is 1.5Gbs 3 would give you 2Gbs.*
Ps the port trunking via LACP seems to be better than my last implementation so yeah it could serve 2 x 1gbs to 2 clients.
Not sure what I used last time but 802.3ad via LACP looks much better.
Even switches with LACP are very cheap now £60 https://www.amazon.co.uk/NETGEAR-GS108T-...B000RAILSQ
PSU for 4 adapters £10 https://www.amazon.co.uk/GEREE-Converter...B06XG96WF2
Iperf is a great tool for benchmarking all this.

Give it a go and post some results but the USB2.0 will just bottleneck just about everything.
