Components of HDD

The components of the hard disk are very simple to understand by every one. The whole process begins with a steel case that on a side has the operating board that it contains coils, processors & many circuits, and on the other side it is written the capacity the speed and the way to use the hard disk. Inside the metal case we can find some disk and two or more mechanicals arm. The disks inside are very similar to a CD but it can be written on the both sides. The disks are rotating with the help of a small motor that can reach certain speeds. On those disks the information is written with the help of the mechanical arms that on the end of it are also connected to an engine & on the other end we can found some writing heads that perform actions on the disks.
The hard disk is the main non-volatile memory component of any system that brings together a personal computer. Compound by electronically & mechanical elements the hard drive is the component that can stock all of the data from your computer in non-volatile way but in the same time the data are stocked in normal & safe conditions. The main properties of the hard disk are the access speed for the transmission of the data & the hard capacity. Just like in the RAM memory if the hard disk has a bigger capacity and it is faster the better for your computer.
If you want to choose a hard disk that runs better on your computer you must first know what programs will run more often on your computer & you may consider the next example a better way to make the difference when you by a new hard disk: if you like to work with video recordings you will need a hard disk that is bigger in the stocking module or if you want to create a server files on your computer you will need a hard disk that runs in great speeds usually like the aspect of a RAID system.
Another main characteristic of a hard drive is the dimension of the memory tampon (buffer). This property is always forgotten but it will need some general attention from you because it helps the hard disk to temporary record some data on your hard disk. The bigger the buffer is you will notice that the computer is faster because the data that you are trying to access can be found in that zone so the performances are greatly increase. One thing you must know before we can continue, the hard disk are the weaker components in the computer even today when it cams to searching/riding/writing that takes place on the hard disk.
For better understandings of the hard drive we will take all of the main properties of the hard drive & give some information about them:
- the mainframe of connection – this option depends on your type of motherboard. The hard drives can have two different interfaces like P-ATA or S-ATA. The difference between them is the speed of the data on transmission from the motherboard to the hard disk. Of course the S-ATA has a greater speed for the transmission of the data but this option is available only your motherboard can sustain it.
- the capacity – this is an option that you must decide first what are you going to use your PC first.
- the buffer – the buffer is usually measured in MB & it indicates the dimension of a tampon memory in witch we can find some data that where recently access. The bigger the buffer the better for your computer but this option usually makes the hard disk more expensive.
- the speed – the speed of the hard drive is measured in RPM (rotation per minute)
