gollark: Obviously you should upload to osmarks.tk™, we have about 1.5TB available on various disks.

gollark: Well, the obvious solution is to buy a raspberry pi 4, network switch and SATA to USB 3 bridge, then run storage over the network.

gollark: Your options involve:- suffer- bigger caddy somehow- run external SATA cable

gollark: Did you know? osmarksgrafana™ *cannot* be escaped.
