Thanks everyone, because I’m exceedingly cheap and lazy (and this is a backup solution), I ended up getting a sabrent usb dock and 4 tb HDD for now. This will also allow me to use all of the smaller drives I’ve been accumulating over the years. Also picked up some nice plastic drive cases to organize all of it. This is definitely the lowest tech solution, but I’m happy with it.

Failure rates of pc parts seem unreasonably high for the money we spend. My last build required the GPU and MB to be RMA’d and I just had a two month old NVMe drive die. Further, there doesn’t seem to be any data on which parts fail the least/most.
