Re: Nice gadget?
These devices were never intended to stay in use in the long term. They're shipped out to a customer to load on data to transfer into AWS where that transfer is faster than going over the internet (see also: station wagon full of DLT tapes). They shouldn't stay on prem for longer than it takes to load it up with the data going into AWS.
As for re-use, they're essentially relatively fancy encrypted hard drives with a NAS front end. There's probably limited value in re-use, although the ruggedisation might make them interesting in niche cases.
