You need to use a heat gun or hair dryer to heat up the adhesive this way you won't crack the screen. Solid State Drives (SSD) are drives that have no movable parts which is one of the reasons they are faster. They are similar to flash cards and usb drives but are 5 to 6 times faster and higher quality components. Lots of people will store the operating system on an SSD and use a regular HHD for mass file storage they are cheaper and you get more storage but they are slower
