Hard drive

Hard drive is a medium for storing data and a system to run all the programs that exist on the computer. Type is very much of a variety of corporate hard drives.

Hard disks have a limited time use, but the duration depends on the frequency of usage in the computer. If ignited nonstop 24 hours, then the age of the hard disk is not more than 2 years or equivalent to 6000-7000 hours.

For that need to be changes over time, and do not forget memback-up data is already saved. Hard disk can not be repaired by just anyone, only the manufacturer who issued the product that can fix it. Itupun limited to mechanical, was damage caused by the sector damaged, can not be repaired and must be replaced with new ones.

The process of making the hard disk itself consists of layers of magnetic sprayed on the surface of the plate is smooth with high technology (Susan B. Sasser et al, 1996). Like a floppy disk or CD Room, then the process of making the hard disk is the same. If the head floppy disk form large, then the hard disk is smaller. Besides, every dish on the hard disk must be spun at high speed, so natural that in a certain time should be replaced with new ones.

On the hard disk low speed (5400 rpm) is usually cheaper than the high speed of 7200 rpm, although the amount of the same capacity. For hard disk high speed is more often found on the user server to the network (Network). As for the low speed is usually used in personal computers at home-the home or office that does not use the network.

Advantages of using a high speed is to access programs and store data more quickly, but in quotes that the difference between the two is subtle, so can not be seen clearly the difference.

Along with the technology running, then the production lately, especially for a large capacity, the plant dare warranty 1-2 years. This is quite reasonable because the amount of space available, and with advances in technology the weaknesses that occurred earlier can be resolved at this time.

Unfortunately not all manufacturers have iktikat well in overcoming the competition, they ignore the quality of hard disks produced in pursuit of price competition. In the end consumers can choose their own where the production that he thinks good or less good.
