Why is the change from a HDD (= Hard Disk Drive) to a SSD (= Solid State Drive) so useful?

• Lower power consumption, therefore more battery life and less waste heat.

• Much faster! Shorter start and access times for the operating system and programs.

• No moving parts, therefore mechanical robustness (improved shock resistance).

• Lower weight and more silent.
