Hard disk or hard drive is an important part of the system unit.It provides storage of user files and data.If you are thinking how to choose the hard drive, you should know a few parameters.
consider the main characteristics of the hard drive.
first parameter to which you should pay attention to when choosing - is the volume of the device.It refers to the amount of space on your hard drive, that is, the amount of information recorded by the user on the hard drive.The volume of the device is measured in gigabytes and terabytes, and the bigger it is, the better.Who better to buy a hard drive capacity from terabytes.
second important nuance in dealing with the problem of how to select the hard disk is the interface - the basis of the interaction of all systems.Usually connect the hard drive to the motherboard performed by the corresponding interface.IDE used previously, at the moment it is obsolete.Currently widely used interface SATA, three options presented is considered the most modern SATA3.
When answering the question of how to select the hard disk, it is worth mentioning about such an important moment, as spindle speed.This parameter determines the speed of information exchange.The higher the figure, the better.The best is 7200 rpm.
Another very important parameter is the buffer memory, which is memory hard drive, in which the storage of data already read from it, but not transmitted through the interface connection.The more memory, the more likely that there are important data that is not required to search the disk.This affects the increase in speed of the hard drive.Currently, the maximum memory size is 64 megabytes.
Another parameter influencing the decision of a problem, how to choose the hard drive is the form factor.By this is understood the physical dimensions, ie height, thickness and width.Currently there are two 2.5-inch and 3.5.The first option is designed for use in laptops, and the second - for the usual system blocks.If you consider how to select a hard drive to the laptop, it is necessary to say that in most cases the speed of the spindle is equal to 5400 rpm.But the second type of hard drive is designed for installation in a conventional system units.
In terms of reliability we can say that all manufacturers are about the same, as it is one of the key quality criteria for them.And when it comes to the issue of how to choose a removable hard drive, then it is possible to give preference to a series of Western Digital Caviar Green, particularly silent operation and low temperature.The cooling of the hard disk should be paid special attention.If the front of the compartment with the hard disk has a well-blown body, then you can do without a few extra coolers.
So, now you know not only how to choose the hard drive, but there are some nuances in this basic choice.
