Computer users know that at one point, despite the size of the hard drive, a moment comes when there is no free space on it. A large amount of information is collected on the hard drive, which we do not want to delete. In these cases, external drives save us.
In addition to the fact that external drives make it possible to additionally store large amounts of information, also storage media
are mobile, this makes it possible to transfer the necessary information. Now we will tell you how to choose an external hard drive, what indicators you should pay attention to.
Volume
Considering what you want to keep on the external hard drive, its volume is selected. For example, if you want to store quite large databases there or create a collection of your favorite films and, in principle, work with a relatively large amount of information, you will need a disk with a capacity of about 3 terabytes.
Of course, you can buy a disk with a capacity of even 18 terabytes, but keep in mind that the price will be much higher.
If you do not need such large volumes, then a more optimal option is a 1 terabyte disk. At the moment, this volume is the most popular. Choosing computers and their components on the site https://spb.metro-cc.ru/category/bytovaya-tehnika/kompyutery, you can find the optimal system for any task.
Due to the fact that you can buy computers, software, and peripheral devices, and storage media at one point of sale, you can immediately equip your computer with everything you need.
The size
The disk size can be 3.5 or 2.5 inches. The 2.5 form factor is used to produce hard drives for portable devices and laptops. Accordingly, 2.5-inch hard drives will be quite compact, they can only work from USB and will not require additional power. Among other things, they will be the most stable. Only 2.5-inch hard drives will run slower than 3.5-inch hard drives.
The 3.5-inch form factor is used to make drives that are designed for desktop computers. Such hard drives cost less and have a fairly high speed. On sale there is the opportunity to find models with a capacity of up to 18 terabytes, but there is more choice up to 8 terabytes. Among the shortcomings, it should be noted that such external drives will be more than 2.5 inch.
