you were lucky

is this a production system ??
If so, i'd suggest you start looking for a new boss, one that gives you 
enough money to at least run software raid.
Ask him how much a complete data loss costs ?
Not just your salary for the time you try to recover, but also his
time, and the rest of the workers while the system is down because he
saved money on disk space. And dont get me started about backup.

Remober, if you DO go raid, you NEED to know when a disk goes down,
because if not, you might as well not run raid at all. This means
some sort of management software that keeps an eye on the disks, and
emails you when one fails. Hotswap _MIGHT_ not be needed, but it is
nice.
