Right now my home server consists of a thinkcentre tiny and a single 6tb usb3 external drive.
The goal is to eventually build out a nas, but that’s not in my budget at the moment.
Is there some kind of external device I can put multiple 3.5inch drives, has plenty of bandwidth for said drives, and routes through either usb3 or C and can potentially allow me to have a raid (or raid similar) setup for redundancy for the data?
Yeah, you can get external USB enclosures for multiple drives, and set up software RAID.
I wouldn’t recommend it, though, because if the connection is interrupted at all, one or more disks can drop off and the array is degraded or failed, which can lead to degraded performance during rebuild at best, or a loss of some or all data at worst.
Which part wouldn’t you recommend, raid on those or just the type of product in general?
Anything over USB.
