Replace HDD With SSD for Macbook Pro Unibody, Mid 2012

The traditional spinning hard drive is the basic nonvolatile storage on a computer. That is, information on it doesn't "go away" when you turn off the system, as is the case with data stored in RAM. A hard drive is essentially a metal platter with a magnetic coating that stores your data. A read/write head on an arm accesses the data while the platters are spinning.
An SSD does functionally everything a hard drive does, but data is instead stored on interconnected flash memory chips that retain the data even when there's no power present. Speed is where SSDs shine. An SSD-equipped PC will boot in less than a minute, and often in just seconds. A hard drive requires time to speed up to operating specs, and will continue to be slower than an SSD during normal use.
