Guys, a question here, just got some bucks to spend on ssd lol

Which one is better compare the 500gb Seagate Momentus XT with 80gb/120gb intel ssd?

We can avoid the price and storage talk here. Just mainly for the performance as I used to open multiple apps and games simultaneously all the time.

If in term of performance, can see any difference in games?

Which is better if I want a continuous write and read drive? I used to transfer a lot of files and accept bigger files 24/7 a day and I keep my PC running for whole month without shut it down. Can this drive last long with it?
