What is the best external hard drive? Optimal device selection

Many computer users are unpleasantly surprised by the fact that there is not enough space on the internal hard drive to store files. The speed with which data is transmitted today in the Internet, is growing every day. The amount of data that needs to be saved is also increasing. Computer memory no longer holds a collection of movies, music and photos? The hard disk can become an exit from this situation. This article will help you figure out which best external hard drive should be purchased based on the requirements for the device.

Choosing a device, the question naturally arises: "Which hard drive is better?" The answer, as always, is on the surface. You should clearly know the purpose for which the device is purchased. Which good hard drive is best for storing the home video collection, and what is the best external hard drive it would be more logical to use as a container for temporarily storing files. The main parameter of any external disk is the amount of memory. The standard for disks, whose form factor is 2.5 inches, is the volume of 250, 320 or 500 GB. A drive with less memory to buy does not make sense, since they are not much cheaper, and the memory stock will never be superfluous. And what good hard disk can have a volume of 1TB or more? This amount of memory can boast 3.5 inch models. They are recommended to be used as a repository of files. A significant disadvantage of such disks is that they need additional power. Which hard drive is better suited for immediate needs, ultimately the consumer decides.

It should be understood which is the best external hard drive would not be, it's just a normal hard drive, enclosed in a plastic, rubberized or metal casing. For use in extreme conditions, devices with a metal or rubberized casing are perfect. Such hard drives are protected from mechanical impact better than others.

In order to decide which is the best external hard drive, you need to know the speed of its work. The faster the hard drive runs, the higher its cost. If the speed of the device is a factor influencing the decision making, then a small overpayment would be quite appropriate. The speed of the hard drive is determined by two factors: the speed with which the spindle rotates and the speed of average access. Those who decided to choose a disc more quickly, it is best to look at models that have a modern interface that allows you to quickly transfer data from your computer to an external drive. In terms of speed, 3.5 inch models are preferable. The optimum rotation speed at them is 7200 rpm. At 2.5 inch disks this parameter is more modest - 5400 rpm.

To find out how much the selected disk will be compatible with the PC, it is necessary to find out which file system it supports. The most popular are FAT32 and NTFS. Each of them has strengths and weaknesses. The advantages of NTFS include support for files larger than 4GB. This is a definite plus for those who are going to store high-resolution video on the hard disk. FAT32 also has its advantages, it is compatible not only with modern OS, but also with most obsolete ones. Although most HDD models support both file systems and can easily be formatted in FAT32 or NTFS.

And of course the design of the device plays an important role in the choice. As a rule, with relatively the same technical characteristics of the two hard drives, the buyer chooses the one that in his opinion is more attractive externally.

So, now we know that when choosing a hard disk, you should pay attention to the following parameters: capacity, speed, compatibility with the PC file system and size.
