Running a Parity Archive node

About two years ago I set up two Parity archive nodes on custom-built Linux boxes with internal 4TB SSD hard drives (don’t ask – I have a reason). Currently, they are both at 94% full with about 220 GB of free space, and I’m looking for any ideas of where to go from here.

Is anyone out there running Parity archive nodes? Are you anticipating it outgrowing a 4TB drive? Are you running the nodes locally? Are you running them on a datacenter? How much is it costing you? I can’t find an internal SSD any larger than 4TB – is an internal drive needed? I’m pretty sure an SSD is needed - is that still true?

Any help or advice from people running archive nodes would be appreciated. I’ll collect together and write up a Medium post if I get some useful information.
