4x hard drive to one usb connection?

[tclancey]

Hi folks.

I have 4 old sata driven hanging around from old systems. They're only 80Gb but they are all identical, which made me think I should be able to build a speedy raid from them. The problem being I don't want them in a PC, I'd like them connected to a raspberry pi.

I suppose the first question is: would any raid benefit be lost trying to shove data through a usb 2 port, and second does hardware exist for this?

I could just get a few sata to usb controllers and hook them up separately, but where is the fun in that!!

Any ideas welcome. Thanks.

Even a single SATA disk will be slowed down by a USB 2 port.

And yes you can get a RAID box for 4 disks https://www.newegg.com/RAID-Enclosure-Subsystems/SubCategory/ID-509

$150

And yes, going through a USB 2.0 will choke that performance.
