If you guys were going to change out a hard drive in a laptop to something faster? would you get a hybrid SSD drive like the Seagate Momentus XT 500GB or get a legit 128GB-256GB SSD? Seagate Momentus XT ST95005620AS 500GB 7200 RPM 32... I was looking that that for my school laptop. It has a 500GB 5400rpm drive in it now. Kind of slow.
