SSD - solid state disk

Abbreviated SSD, a solid state disk is a high-performance plug-and-play storage device that contains no moving parts. SSD components include either DRAM or EEPROM memory boards, a memory bus board, a CPU, and a battery card.

Because they contain their own CPUs to manage data storage, they are a lot faster (18MBps for SCSI-II and 35 MBps for UltraWide SCSI interfaces) than conventional rotating hard disks ; therefore, they produce highest possible I/O rates.

WEBOPEDIA FACTOID
The phrases solid state disk and flash are often used interchangeably, but technically speaking, solid state disk means the physical device that houses the flash module.

SSDs are most effective for server applications and server systems, where I/O response time is crucial. Data stored on SSDs should include anything that creates bottlenecks, such as databases, swap files, library and index files, and authorization and login information.

While solid state disk (SSD) is the most common acronym, SSD is also used for solid state drive or solid state disk drive.
