Just for sh!ts and giggles, I connected a USB hub to the USB3 port on my Linksys WRT3200ACM router running OpenWRT to see what would happen. Hey, I live on the edge.
Somewhat surprisingly, it works. LuCI couldn’t see the new drive; but I was able to initialize, partition, and format an 8TB Seagate Exos drive in the shell, after which it was available for use as a shared drive in LuCI. That’s in addition to the existing 4TB Seagate IronWolf drive.
So now I have 12TB of storage coming off the router, which I use for backups of backups as well as easily-replaced stuff like downloads that I want to make available across the LAN.
Anything actually important that’s not in itself a backup of a backup is backed up to B2 using GoodSync, thus also making it available remotely on my laptop using Mountain Duck in addition to backupping it.
I decided to try that as opposed to buying another Tiny PC to use as a NAS controller, and saved a couple hundred bucks in the process.
Life is good.
