I bought a 30Gb vertex as i wanted to test SSD, and i didn't want to spend too much on what is a new, constantly evolving technology. At the moment, after installing the OS and the programs i use, i have 3GB free. It's shaved my boot up time from over 1 minute, down to roughly 36 seconds, so it's a definite improvement, but i'm not that impressed with it in all honesty on the whole, and i'm glad i didn't stump up more than the £100 i paid for it. I don't play games, all i use the PC for is web surfing, downloading stuff, playing around with virtual machines, and listening to music and watching videos. I don't really sense that things are that much snappier when loading applications. I previously had 2 Samsung 1TB F1's in a raid1. Part of me thinks it's down to what i use the pc for, and that i would get more out of it if i bought a couple larger SSD drives, as then at least i would be able to feel the difference when transferring files between the two etc. Maybe i should have bought a larger SSD drive in the first place rather than my 30GB vertex, as then maybe i could have put everything i needed on it, rather than installing the main things on the SSD, and the rest of my stuff on the F1's. Don't get me wrong, it's a great improvement when booting up and shutting down the PC, but surely i can't be the only person to question whether it's worth the money to shave a second or two of the time it takes to open Microsoft Word........
