Solid-state drive

An SDD (solid-state drive) is a data storage device which uses solid state memories to store persistent data.

The functionality of SSDs emerged from traditional hard disk drives (HDDs) and electromechanical devices with rotating disks and moving writing and reading heads. In contrast to the traditional hard drives, SSDs use microchips and do not contain any moving parts. This retains data in the non-volatile memory chips.


The classification of the SSDs is predominantly based on the SD card classes. If you need more information about the SDD classes, please use the Contact form.
