Steven brings up a good point here. Some adminsitrators go so far as
to buy each of their drives from different places so as to try to get
different lot numbers. The theory is that drives in the same lot can go
bad at the same time (which indeed I've seen happen).

I recently bought 4 drives for a raid 5 array and bought 2 drives from
NewEgg, 1 from CDW and 1 from somewhere else. But with my luck with
hard drives, the 2 that came from Newegg where in different lot numbers,
but the 1 from CDW and from another company had the same manufacture
date.

I can't remember where, but I saw someplace that would sell you X
number of drives and make sure they were all in different lot numbers.

Of course, you already bought the drives, right? What brand are they?
Do they come from Sun when you buy the array? With 24 drives, you can
count on a few breaking within the first couple months and also several
breaking around 4-5 years.
