+1 for SSD! These things are awesome! I was hesitant to pay so much for so little space, but I pulled the trigger. I have one in my Core i7 build, and wow, just amazing. My PC boots in 15 seconds. I can't even imagine what it's like in RAID. That's just wrong.
For those who think this is too small, the idea is you put your OS and important programs on this, and your data and other programs on a regular HDD. Back in the day people said a memory upgrade was the single biggest speed boost you could do on a computer, now it's SSD.
