SSD & it's Types (SLC, MLC, TLC)

The Anatomy of an SSD

SSD with two enclosed NAND flash memory chips installed. The controller chip is designed by PHISON.

A. NAND Flash: The part where your data is stored, in blocks of non-volatile (does not require power to maintain data) memory.
B. DDR Memory: Small amount of volatile memory (requires power to maintain data) used to cache information for future access. Not available on all SSDs.
C. Controller: Acts as the main connector between the NAND flash and your computer. The controller also contains the firmware that helps manage your SSD.

TYPES OF SSD

1. Single Level Cell (SLC)
2. eMLC (enterprise Multi Level Cell)
3. MLC (Multi Level Cell)
4. TLC (Triple Level Cell)
