8 drives over USB 3.0 won't perform well, though a single SATA connection isn't without issues either. That cable will be the I/O limiter in an uncommon fashion. I'd go for the eSATA converter option but neither is ideal. A big question is how will the drives be seen by Proxmox? If it's as one big drive that means you're SOL for safe storage options, if so I wouldn't store anything you don't want to lose on there and just make a ZFS storage pool of it in Proxmox.
As for plans I would down the line look at Ceph because it does really well with cheap hardware. No need for a competent RAID controller etc.
Ya I realize this isn’t a great way to go about storage but I already have the enclosure so I might as well use it for now. At some point down the line I will build something that will work better.
If I connect it using USB I am able to see each drive individually in Proxmox. I am unsure if it will be the same if I use eSATA. In the manual it says that the eSATA interface card needs to support Port Multiplier which I fear means the eSATA to SATA option may not work but I was hoping someone here may know more about that.
If I have to go the USB route and I am able to use each drive individually, would you recommend going with a ZFS pool or ceph?
I'd go with ZFS because balancing between the included disk in a Ceph pool will consume I/O and especially if one disk fails, that rebuild would take days if not weeks. If you want to try Ceph then don't include all the 8 drives initially and see how the performance is with the minimum 3 drives.
Thanks, I may hold off on ceph for now in that case
