This could be useful for bootstrapping a shared-nothing cluster or a disaster recovery node. A comparable amount of space in a storage array might occupy a 2-4U chassis, which would be somewhat less convenient to transport.

This thing isn't going to be cheap, so you'd probably want a more frequent transfer to justify it. Maybe sneaker net database journals or backups every week?

TAA-compliant, so some portion of the target market is US government and related contractors.

It's not that alien. We recently migrated to a different storage provider and used something like this to move 200TB of data. Seems like a fancier version of the Google transfer appliance (https://cloud.google.com/transfer-appliance/docs/4.0/overvie...).

A data center has backup plans. This is more for data on the go. Think of a fashion show where the production shoots tens of TBs in high resolution and they can’t afford to setup a server room because it would be impractical. You get one of these and you’re done.

Film production crew although it doesn't have a video digital out. But you might not even need it if you are only after storage, 8K RedCode raw is around ~7TB / hours

Radio astronomer working with VLBI, for example. (less boring than large corporate data migrations)

Not datacenter related but i recall someone had a job of being a data mule between California and Australia to ship dailies to the VFX studio (in Australia) by hopping on the flight every day. I can imagine something like this (smaller) to be carry-on.
