Definition
A solid state drive is primarily a data storage device, for use in computing applications that traditionally use a hard disk drive.
A solid state drive is based on non-volatile memory instead of the spinning platter and mechanical-magnetic head found in a conventional hard disk drive. With no moving parts, a solid state drive eliminates seek time, latency and other electro-mechanical delays and failures associated with a conventional hard disk drive.
Advantages
* Faster startup - Since no spin-up required.
* Faster read time – In some cases, twice or more than that of the fastest hard drives.
* Low read and write latency (seek) time, hundreds of times faster than a mechanical disk.
* Faster boot and application launch time - Result of the faster read and especially seek time. But only if application already resides in flash and is more dependent on read speed than other issues, eg. OS bootup that detects devices will not be significantly sped up even with faster seeks & reads.
* Lower power consumption and heat production - no mechanical parts results in less power consumption.
* No noise - Lack of mechanical parts makes the SSD completely silent.
* Better mechanical reliability - Lack of mechanical parts results in less wear and tear. High level of ability to endure extreme shock, vibration and temperatures, which apply to laptops and other mobile devices, or when transported.
* Security - allowing a very quick "wipe" of all data stored.
* Deterministic performance - unlike mechanical hard drives, performance of SSDs is constant and deterministic across the entire storage. "Seek" time is constant, and performance does not deteriorate as the media fills up (See: Fragmentation).
* Lower weight and (depending upon type) size
* Faster than conventional disks on random I/O
