- 8What are the three types of secondary storage, and what are their characteristics?Magnetic - Fast access speed, pretty cheap per unit, not portable as of moving parts and large size
Optical - Not a lot of storage and not fast access speed, but small and durable so good portability, cheap as well
Solid State - Very durable and has a small size for good portability, fast access speed and a good amount of storage, but very expensive
