Internal hard disk

Detailed explanation-1: -Hard disks hold a vast amount of data and are relatively cheap, so on a per-byte basis they are the amongst the cheapest form of storage, although magnetic tape is cheaper. An internal hard disk is not intended to be portable-it is screwed to the computer chassis as a permanent fixture unless a replacement is needed.
Detailed explanation-2: -Internal hard drives are located inside your computer. Unlike an external hard drive, these drives are not portable and only be used by the computer they inhabit.
Detailed explanation-3: -HDDs have a relatively slow read/write speed, particularly when compared to their main alternative, the Solid State Drive. They have a number of moving parts, which means knocks can easily damage the device. This makes it generally a risky option as a portable storage device.
