I’d say you are way off with this kind of equipment.
As a start you could get a Banana Pi or an Odroid with a 1- 4 TB disk and a DSL line like max 100 up/down.
Yesterday got me 12 GB egress and 17 GB ingress.
Calculate for yourself how long it would take to fill 24 TB. This is for the time being. Nobody can tell the future of it. If Storjlabs will be able to sign some big deals demand can grow. But it is probably never to late to add more disks or increase disk size when it happends.
I would start low and just make sure that your capacity grows with the data that comes in.
Community here is really awesome.
