I've always considered this a huge advantage of software raid1. Even if
everything on a machine melts except for one drive, you can recover
the data from it and you don't need a special controller to do it. On
windows, you need the server versions to do mirroring, though.
If you can tolerate losing an hour's work or so, you could just schedule
rsync commands to keep copies updated on another (perhaps external)
drive or to another machine on the network - or get a Mac with it's
'time machine' backup. This approach is actually safer than RAID alone,
since operator or software errors will wipe out your mirrored copy
instantly as well with RAID.
Unfortunately I can't use software RAID1 because of this:

First, you should probably get your applications from a company that
doesn't hate its customers... But aside from that, this restriction
should only apply to the place where you install the app, not where you
store your own work. Why don't you ghost-image (or use the free and
very nice clonezilla-live) your system disk for a quick bare-metal
restore, and put your own work on a separate raid-mirrored partition?
And since you seem to be very paranoid about your disks, use some other
backup mechanism like rsync to another location at some frequent
intervals too.
