SSD - Solid State Drive
A solid state drive (SSD) is a data storage device that uses solid-state memory to store persistent data. An SSD emulates a hard disk drive, thus easily replacing it in any application.
Solid state, refers to the use of semiconductor devices rather than electromechanical devices. With no moving parts, a solid state drive is:
- usually more robust, effectively eliminating the risk of mechanical failure,
- usually silent,
- and usually enjoys reduced seek time and latency by removing mechanical delays associated with hard disk drives.
A SSD is commonly composed of either NAND flash non-volatile memory or DRAM volatile memory (RAM Disk).
SSD on market today:
- SanDisk (1.8- and 2.5-inch SSD to 64GB)
- PQI (256GB 2.5-inch SSD drive)
- Samsung MTRON Memoright (128 Gb solid state hard disk)
- Toshiba SSD (128GB, 64GB, 32GB)
