Hard drives are not all the same some run at different speeds, and some are different form factors while others are custom or portable such as “Flash” or “Thumb” drives.

Hard drives are traditionally mechanical having a magnetic disc inside it with a write-read head. Though in recent years SSD (Solid State Drive) have hit the consumer market though they are not very economical in terms of how much you pay for what amount you get but prices are improving.

The advantages of a Solid State Hard Drive is that is has no mechanical moving parts so it is less prone to failure and can reach exceptionally high speeds. Most hard drives are rated to last 3-5 years while an SSD can go for 4-10 years.
