SSD vs HDD: What’s the difference?
SSD provides twice as much speed over HDD in I/O Bench marking tests. Here’s how:
“Like a memory stick, there are no moving parts to an SSD. Rather, information is stored in microchips. Conversely, a hard disk drive uses a mechanical arm with a read/write head to move around and read information from the right location on a storage platter. This difference is what makes SSD so much faster.”
