I did this for my first year and a bit for self hosting. It worked great! Really no problems with a USB 3.0 HDD station.
I actually used an HP probook 450 G1 IIRC.
@JustEnoughDucks I started with this setup. Proxmox on my laptop with an external 1 TB USB 3 drive added to proxmox as storage. It would work great for getting started and learning. I/O via USB 3 could be an issue so make sure you don't use this setup for intensive Read/Write operations. But use it as a lab setup and it would work great.
PS: Once I moved to bigger servers, I still use my laptop proxmox for testing services before I roll them out to my production servers.
The difference between them is surprisingly small. 35% maximum.
I have my new server still using the USB3.0 hub while I am designing and printing a case for my main PC.
Flexense did an analysis on 1-4 threads of file copy and other things.
Performance only started to really degrade at 3 thread count medium and large files.
File searching, file delete, duplication searching, disk space analysis, etc.. were all almost identical.
Though it pretty much negates all read benefit of ZFS mirrors and raid1, it is definitely fine for a home server with only 1-2 media streams. I definitely have run into IO bottlenecks, but not frequently. Though that was without a GPU and direct streaming. With storing everything in AV1 and h265 with an AV1 enabled GPU like the Arc380, actually it will be able to handle the IO needs, though I still am upgrading to sata
