Hard drives are storage devices in computers that facilitate the retrieval of information from the device. Storage and retrieval of data is made possible by the platters that constitute these hard drives. These platters are coated with magnetic substance and take up the form of rotating disks. They store data even when the device is powered off. Different hard disks are categorized according to their capacity. This may be measured in terms of terabytes or gigabytes.

Necessity for a driving test
It is essential to carry out a test on the hard drive to establish that it is in good condition. There are several practical driving tests available online that may enable you to understand why your computer is unnecessarily slow or why you may be experiencing errors when moving or deleting files. Occasionally, this may be the result of having a virus in your PC but in other cases it may be the result of a hard drive problem. These tests could be done by some applications such as HDD health, Test Disk or Scandisk. If the test generates SMART errors, which may not be fixed by the software programs listed above, then perhaps replacing the hard drive would be the best course of action.

How hard drives affect the speed of computer
Hard drives with a larger storage capacity are more often than not faster than those with a lower capacity. A larger capacity indicates that the computer has more space available for it to handle more tasks at the same time. Inevitably, as the capacity of the hard drive increases, the computer speed will also increase as well. It will become more efficient in completion of new tasks that are being carried out in the background making it more proficient in running applications.

Hacking
This is whereby an individual who is adept in computer skills exploits a weakness in a computer system and uses it to gain access to a restricted program. In some cases they gain access to password protected fields and exploit whatever flaws they may find in that system. Computers with slow hard drives make it much easier for a third party to do this. This may result in violation of the computer security and may even result in the deletion of some important files stored in the hard drive.

Effect that faster computers have on hacking
Hackers rely on a slow computer or one that is not able to execute some applications properly to gain access to it. Such a computer may take longer than usual to load applications or run them successfully. In the interim, hackers are able to gain access of your PC or account especially if one is on an open internet connection. Having a fast computer will enable you to reduce the probability of this happening as your applications will be up and running in a very short time. Therefore, a software program such as HDD health should be considered as a practical driving test to ensure that the computer’s hard drive is performing at an optimal speed and therefore reduce the chances of someone hacking into it.
