Solid state drive (SSD) is a flash device with storage capacity similar to a small hard drive . They are faster than other devices. They have no moving parts and last longer than other storage devices.
What characteristics distinguish a SSD from HDD?
The platter inside the hard disk drive is coated with a magnetic media which records data in binary code (1’s and 0’s). A solid state drive does not contain magnetic coatings. Instead, SSDs rely on an embedded processor, or “brain”, and interconnected flash memory chips that retain data even when no power is present.
