How to choose a hard drive

The hard disk is designed to install the system and storage programs. Usually it comes complete with PC. But sometimes the hard disk fails or ceases to cope with the tasks. Then, in front of the owner of the computer there is a question about buying a new one. So, how to choose a hard drive and what to pay attention to?

Currently there are two types of hard drives - SDD and HDD. SDD drives provide high speed, consume a small amount of electricity and absolutely silent. Perhaps their only drawback is a high price. A good SDD is at its cost approaching the processor. That is why HDD is still popular. If you are not constrained in the means, then experts recommend simultaneous installation on the carriers of both types: SDD - to install the operating system, and HDD is for storing movies, photos, games and other programs.

The volume of the hard disk depends on the tasks that it has to be performed. If you do not play heavy games and do not download a large number of films, then you will be sufficiently minimal volume ranging from 500 MB to 2 GB. Now there are hard disks of up to 1 TB, naturally, their price is higher than that of standard. It is best to add 30% to your needs and proceed from the resulting volume.

Pay attention to the hard disk buffer memory, otherwise called the "cache". The higher this indicator, the better.

Large hard disk volume - not a warranty of fast computer. Therefore, look at the speed of rotation of the spindle. The optimal is considered the speed in the range from 5400 to 7200 revolutions per second. Hard drives with a speed of over 10,000 revolutions are designed for professional purposes.

The time spent on the search for the desired information, or the average waiting speed. The lower, the better, ideally - 4 seconds.

Choose a hard disk manufacturer tested by time. Do not chase the new models, the sales time of which does not exceed six months. First, their price is higher, secondly, they can still not "run-by" technologies. Currently the highest reputation for manufacturers such as Segate, Western Digital and Hitachi. Be sure to demand the seller warranty card.

That's basically it. Finally, I would like to note that there are no hard drives with absolute reliability. Therefore, from time to time, back up the data.
