Abstract: You want to buy a computer, you want to buy a good computer, what 
should you pay attention to. I aim to collect all this information from social networks to help 
you get a good computer. 
Keywords: Computer systems and networks, higher educational institutions, Data 
communication and networking, Principles, technologies, protocols.
Today we will look at what HDD drives are, what they are and their features. We will 
find out which of them is the best and which HDD is not worth buying. 
A hard disk is a data storage device used in computers and laptops to install the 
operating system, drivers, programs, as well as to store all kinds of user files. 
HDD is a semi-mechanical, semi-electronic device consisting of magnetic plates, 
read heads, a shaft (motor) and a control panel. The spindle on which the magnetic plates 
are mounted spins them up to several thousand revolutions. per minute. 
It is believed that the higher the spindle torque, the higher the reading speed. 
Although important factors include: random access time and recording density. HDDs differ 
in speed, size and, of course, reliability. This parameter is guaranteed by the manufacturer. 
What are the best manufacturing companies? 
Samsung drivers are the most reliable and fastest. Hitachi also makes a lot of good 
rims but they are slower. HDD firms are western digital with average quality. It turned out 
that this company initially started to produce its products in cheap factories without quality 
equipment. The lowest quality of production of this type of devices from well-known brands
