[K12OSN] Knowledge turned crisis

I started out asking a week or so ago about eide drives with raid
configuration question out of curiosity for future expenditure.
This morning as I was teaching a lesson the server let out a weird,
mechanical noise albiet only for a few seconds.
I was not concerned about the lack of redundancy in the data, but now I
am. It was probably nothing, but My academic questions about the best
configuration suddenly seem more practical.
I gather that many of you have a problem with the Promise raid
controllers. I also see that alot seem to favour the 3ware
controllers. I feel I need to get a solution in place soon, probably
over the Christmas holidays.
So, in a nutshell:
anything wrong with 4 - 80 GB 7200rpm EIDE drives with 8Mb cache running
on a raid controller(as yet to be determined) in a configuration like 1
+ 0 or 0 + 1? This gets me effectively 80GB capacity and redundancy
with the ability to withstand 2 drives dying, right?
this would get me, correct me if I am wrong, both redundancy and some
performance increase, yes?
old drives, with no redundancy, are old smallscsi drives of 5400 rpm
speed on old controller
