Many computer users are unpleasantly surprised by the fact that the internal hard disk is not enough space to store the files.The speed at which data is transmitted today on the Internet, is growing every day.And increases the amount of data that must be preserved.Computer memory is no longer holds a collection of movies, music and photos?The way out of this situation can be the hard disk.This article will help you understand what the best external hard drive must be purchased on the basis of the requirements imposed on the device.
choosing a device, it is quite natural question arises: "What kind of hard drive is better?" The answer, as always, is on the surface.It should clearly know the purpose for which the device is purchased.What a nice hard drive ideal for storing home video collection, and what is the best external hard drive it would be logical to use as a container for temporary storage of files.The main parameter of any external disk is a memory.The standard for disk form factor is 2.5 inches, the volume is considered to be 250, 320 or 500GB.Disc with less memory to buy does not make sense, since they are not much cheaper, and the supply of memory never will not be superfluous.And what a good hard drive may have a capacity of 1TB and more?That memory can boast a 3.5-inch model.They are recommended for use as a storage tethers.A significant disadvantage of these discs is that they need extra food.Which hard drive is better suited to the immediate needs, ultimately the consumer decides.
should understand what is the best external hard drive would not be, it's just an ordinary hard drive encased in plastic, rubber or metal casing.For use in extreme conditions are ideal devices with metal or rubberized case.Such drives are protected against mechanical impacts better than others.
order to decide what the best external hard drive, you need to know its speed.The faster the hard drive, the higher its value.If the speed of the device is a factor in the decision, a small overpayment will be quite appropriate.The speed of the hard drive is determined by two parameters: the speed at which rotates the spindle and the average speed of access.Those who decided to choose the more bright disk, it is best to look at the models that have a modern interface that allows you to quickly transfer data from a computer to an external drive.In terms of speed, 3.5 inch model is preferable.Optimal rotational speed from them is 7200 / min.At the 2.5-inch disks, the figure modest - 5400 rev / min.
To learn how the selected disc will be compatible with your PC, you need to find out what file system it supports.The most popular - FAT32 and NTFS.Each of them has strengths and weaknesses.The advantages include NTFS support files larger than 4GB.This is a definite plus for those who are going to be stored on your hard drive for high definition video.In FAT32 also has its advantages, it is not only compatible with modern operating systems, but also with most of the legacy.Although most models of hard drives support both file systems and can be easily formatted to FAT32, or NTFS.
And certainly not the last role played by design in the selection of the device.As a rule, at relatively the same technical characteristics of the two hard drives, the buyer chooses the one that in his opinion, more attractive appearance.
So now we know that when choosing a hard drive should be given to the following parameters: capacity, performance, compatibility with PC's file system and size.
