It doesn't actually change the speed of the computer, but it can change how fast the computer 'feels' because while the PC is reading/writing from the hard drive other things are slower. The longer the data takes to read or write, the slower the computer feels. Because of this faster hard drives are often part of performance class machines.
It doesn't.
speed of ram, speed of cpu, how empty the hard disk drive is
A disk
By making sure you don't overfill it with data. Also keeping your computer clean by using administrative tools such as disk defragmenter will keep your hard disk functioning well and can even improve the speed of the computer.
hard disk
hard disk is a collection power of computer and all the data are store in hard disk for the the long time save.
A hard disk acts as a storage device for data. Data is also retrieved from the hard disk. The data that is kept in the hard disk is not erased even when the computer is switched off.
The computer's hard disk stores data - be that the operating system, application programs, documents or virtual memory.Stores data that needs to be kept between times when the computer is turned off.
RAM alowes the computer to load the computer things faster Another answer: Ram stands for Random Access Memory. A disk loads data into ram. Rather than have the disk return to one spot for the disk drive spot to pick up the next piece of data, the central processing unit can simply go to the RAM and get it. It is not restricted by the speed of a piece of machinery.

that depends on the speed of your computer
One way of recovering data from a dead hard disk would be to get it repaired at a computer shop and buy an external hard disk enclosure that is compatible with the hard disk. Then you can mount the hard drive and transfer data across to the desired computer.
