HDD devices such as early iPods were susceptible to damage from impacts such as being dropped, vibrations and the movements associated with running and exercising. New iTouches, though, are Flash based so they are able to be used with minimal fear of damage during exercise and other physical activities.


Though SSDs are more expensive and have less overall storage capacity compared to HDDs, they are superior to HDDs when it comes to speed. Computers and other devices equipped with SSDs can boot-up in seconds and transfer files and other information much faster than devices equipped with HDDs.
