The traditional HDD, also know as spinning hard drive, is the basic nonvolatile storage on a computer.  Unlike the data on the system memory when you turn the system off, Hard drives are essentially metal platters with a 

magnetic coating and it doesn't "go away".  That coating stores your data.  A read/write head on an arm accesses the data while the platters are spinning in a hard drive enclosure.

Doing much the same job functionally, (An SSD(olid-state drive) can save your data while the system is off, booting your system, etc. The difference is the data is stored on interconnected flash memory chips that retain the 

data even when there's no power present instead of a magnetic coating on top of platters, . These flash memory chips differ from the flash memory in USB thumb drives in the type and speed of the memory. The flash memory 

in SSDs is faster and more reliable than the flash memory in USB thumb drives.
