I don't think (last time I tried) that there's a way to switch RAID level in-place so expanding that in future will require starting again and copying to and then back from other drives again.
Sorry, that's me not being clear about my intentions.
I'll create a RAID1 array now with 2 disks. In future I may add a second RAID1 array with two additional disks. OK this won't appear as a single volume (unless I use LVM? Never really played with that, really should), but for my purposes it shouldn't be a major problem - there's plenty of ways I could naturally split the data that I'm storing across two volumes.
Good points though.
