SSD stands for Solid State Drive, which is the latest technology of HDD. HDD, on the other hand, stands for Hard Disk Drive. Since it is like a more sophisticated memory stick, the SSD stores information on microchips and contains no moving parts. On the other hand, a hard disk drive records information on a storage platter by moving a mechanical arm with a read/write head over a spinning platter. The platter inside the hard disk drive is coated with a magnetic media, which records data in binary code. A solid-state drive (SSD) does not contain magnetic coatings. Instead, they rely on an embedded processor, or the “brain”, as well as on the interconnected flash memory chips, which retain data even when the power is not present.
