You can expect at least one of four 20GB drives to fail much sooner than one 80GB drive, assuming same MTBF numbers on all drives. The MTBF for one 50,000hr MTBF disk is 50,000hr. For four of them, it is 13,500Hr. [ And, if you operate the four for a year, you can expect 1 to fail. ]
So then, the primary advantages of RAID are access speed and data redundancy and the primary advantage of a stand-alone HDD is reliability?
