It's the slowest form of memory storage, but also the cheapest per byte. Your computer has three types of memory at its disposal: cache, RAM, and hard disk. Cache and RAM are both solid-state devices (microchips), and are much faster than hard drives, which are electromechanical devices. The hard drive is limited by the mechanical movement of an arm across a mechanically spinning disk. Cache and RAM have no moving parts, so they do not have that bottleneck.

Because they are the slowest part of a computer. The RAM and CPU have to wait until the data is read before it can be processed and it takes much longer for the disk drive to access it than it does for the CPU to process it.

It is an extension of volatile memory(ram) which is a limited resource. RAM is limited amount of fast memory. Disk is a lot of slow memory.

the interface between harddrive and pc is slow compared to anything else like memory speed or cpu speed ...
