The price of the drive varies with the storage capacity. To install can vary with how much you want to do yourself, or are comfortable doing. Samsung bundles migration and driver software with each of their SSDs to make it seemless to put into existing machines. For installation of this drive you just need a SATA port and power connector (fairly standard nowadays and easy to get or are already included). Doing all this yourself is generally quite easy and seemless, though not a guarantee.
