Thank You for your attention!

-The End-

Upgrade your computer to one that is running on SSD now!!!

Primary Storage Component in SSD:

• the non-volatile NAND flash memory is being used because of the lower cost of NAND flash memory, ability to retain data without constant power supply

NAND flash memory stores data in individual memory cells, each cell consists of a single transistor called the Floating Gate Metal-Oxide Surface Field Effect Transistor (FGMOSFET) that can store electrons

How does a Hard Disk Drive (HDD) work?

Once the read-write head arrives on a certain location on a platter, an electromagnet produces a magnetic field, which aligns data-carrying domains in the underlying track.

2 Types of NAND-Flash:

1) SLC (Single-Level Cell):stores 1 bit, either a 1 or a 0 per cell

2) MLC (Multi-Level Cell): stores 2 bits per cell

• Each domain can be aligned in one of two possible directions, either 1 or 0.
• As these alignments change, they form patterns that correspond to discrete chunks of digital information
