leave it to the professionals
All this tells us is that when you leave storage management to people who "have a PC at home" (and therefore know about disks - ha!) you get amateurish, cobbled together systems using cheap components and lousy architectures that fall over, figuratively speaking, as soon as you look at them.
This study tells us more about the commoditisation of datacentres. Just because eBay will sell you a disk for about the price of a packet of cornflakes means that t'powers that be now object to paying realistic prices for _solutions_ to store their enterprise data.
What we need are some decent disasters (a few more minor earthquakes should do it) to literally shake-up peoples' perception of storage and make them start doing it properly.
