The OP appears to want additional disk space using drives they
already have.  All I can say is it's not a very good idea to span
one filesystem across multiple drives especially when those drives
are themselves quite old.

Because of that, it may not be possible for the OP to get more disk
space and in his position that is just a hardship I would bear,
rather than risk the lost productivity of being out of action for an
extended period of time.

Other reasons for using RAID do include performance, but that may
not be the primary concern and doesn't seem to be the goal of the OP
here.

So when it breaks and you are unable to work for however long, would
that still be worth the saving of NOT buying another one for £15 and
mirroring them?

Cheers,
Andy
