Pros pros: Data transfer to and from solid-state drives is much faster than electromechanical disk drives. * Seek time and latency are also substantially reduced. *Users typically enjoy much faster boot times as well
*In general, SSDs are also more durable and because with no moving parts to break or spin up or down
Cros cros:have slower write times and a set life expectancy. *SSDs have been much more expensive than conventional hard drives.
used Flash-based solid-state drives can be used to create network appliances from general-purpose personal computer hardware.
