A little later, and you're reduced to skip-diving to get the legacy
parts for it, whilst storage of similar size and performance is
sellign for tuppence ha'penny down the road at PC World.

The answer to that is to lay in spare parts at the same time as the
order for the RAID unit. Yes, it increases the initial cost, but at
least you know you have the spares available in five years' time.

The best RAID controllers build that in - they have one or two spare
drives configured in, that don't initially store any data, but can be
swapped in when needed.
