RESEARCH - 2022 169 HDD capacity is measured by the amount of data that fits the device. The first internal hdd had a capacity of only 60 MB. The smallest capacity of hard drives today is 160 GB. Modern devices often have values in the range of 200 to 500 GB. The capacity of some devices can reach up to 3 TB. When choosing, pay attention to your needs and financial capabilities: the higher the capabilities, the more information is suitable, but the price also increases significantly. It is very difficult to combine the last two parameters in one device. So, conventionally, disks are divided into: - universal; - capacitive; - fast. When choosing an internal hdd, you need to decide on the functional tasks. If the computer has one hard disk, then it is better to choose universal models manufactured with an optimal ratio of speed and power. A fast hard disk is used as a system disk. High-capacity disks are chosen for storing large amounts of data. If the choice is made correctly, the whole system will work in a balanced and trouble-free manner. Advantages and disadvantages of different types of internal HDD. Universals have a sufficiently high level of reliability and do not have serious flaws. Fast hard drives, in addition to speed, are very reliable. Disadvantages include rapid heating and noise. Capacity internal HDD is considered the most unreliable, especially models with a capacity of more than 1 TB. The advantages of such hard drives are noise reduction, low power consumption and moderate heating. Features of choosing HDD for a laptop. BEST SCIENTIFIC RESEARCH - 2022 170 Laptops don't need a fast or large internal hdd. It is better to choose a universal hard drive with balanced characteristics. The main differences between internal hdd for a laptop: 1. Devices are smaller and more compact. 2. Hard drives are installed with a spindle speed of 4200 to 5400 rpm, which provides low power consumption. 3. HDD capacity in laptops does not exceed 200 GB. REFERENCES: 1. W.
