Gigbit Ethernet USB 3 device to place USB drive onto network

[albert]

I would appreciate any recommendations for a device I use to make a standard USB drive into a network connected device.

I'm looking for simplicity, so Raspberry Pi is not what I want. I have up until now connected my USB backup drive(s) into my (old) router.  They become SMB mappable drives and any PC that needs to schedule backups can send them to the mapping setup on that PC.

Trouble is removing the old router means I no longer have USB ports to do this. I am connecting the old router just as a USB network hub in the meantime but it's 100Mbps and USB 2 plus it is just eating up power.

Hopefully I explained myself well enough, a few examples but not quite right:

This is too expensive. awesome but way too much.

Only USB 2 and 100Mbps. But nice enough and cheap.

A bit pricey, FAT support only, no good for larger files.

Not really finding a sweet spot.
