It's sad that it's as true today, when you can pick up a 400-GB disk for just over $200, as it was when I got my CS degree and the entire department ran on some DEC-10s that together had a whopping 900 MB of storage (yes, I am old). Since then, every computing environment I've ever worked in has eventually run out of disk space. And let's face it—adding more disks to existing machines can be a PITA (pain in the ass).
