Unless you're running a giant datacenter I don't think that makes a lot of
sense to keep a spare drive on the shelf "just in case".  Unless your
drives are failing frequently (and if they are you're doing something
wrong) you've got a lot of money sitting there on the shelf.  While a drive
will last longer on the shelf, the will still be some degradation which
means by the time you need to replace the drive the spare has developed
problems too. Periodically swapping a drive out just for the heck of it
will create extra stress because the RAID will have to work overtime to
rebuild the array.

My suggestion is to buy the drives that you need now, make sure that your
backups are in order, and make sure that you'll find out quickly if a drive
(or your backup) is failing so that corrective action can be taken promptly.
