Solid-state hard disk is more stable, because there is no rotating motor of ordinary hard disk, so it has excellent shock resistance and is not afraid of collision, impact and vibration.

Compared with ordinary hard disk, solid-state hard disk has the advantages of fast start-up, small reading delay, fast writing speed, no noise, low calorific value, no mechanical failure, wider working temperature range, small size and light weight.

The main disadvantages are: high cost, low capacity, easy to be disturbed by static electricity of power-off magnetic field, limited writing life, difficult data recovery, high energy consumption, and sometimes suspended animation.
