YOUALPA & DEAD YANKEES IN IRAQ I suppose you wasn't using Macs in the old days, or were you? Anyway, if you don't know what it is and what it can be good for, the key is that accessing your computer's RAM is always way faster than accessing your hard drive, no matter how fast this latter can be. The down of it is that Unix-based systems cannot take fully advantage of something like a RAM disk the way Mac pre-OSX systems did, due to the way they manage memory.
