Solid State Disk SSD

For decades, data was stored primarily on mechanical hard drives. These traditional hard disk drives (HDDs) are mostly based on moving parts, like a read/write head that goes back and forth to gather data. This makes HDDs the likeliest computer hardware component to fail.

The new solid-state drives work completely differently. They use a simple memory chip called NAND flash memory, which has no moving parts and near-instant access times.
