Solid State Drive

SSD uses RAM and Flash chips instead of rotating disks, dramatically lowering response time and offering extremely high input/output speeds while using less power and space. SSD performance does not decline over time as it does with rotating disks. SSD is more reliable due to lack of moving parts and can withstand greater shocks and vibrations. It uses less power than rotating disks and has benefits for performance, reliability, endurance, and resistance to environmental factors.

SSD: A Better Solution

Instead of rotating disks, solid state disks (SSD) use RAM and Flash chips. SSD: Dramatically lowers response time (latency) Offers extremely high inputs / outputs / second (IOPS) Uses less power and less space
