Most computer users feel complicated to install an internal hard drive into their computers, they need a hard drive with extra storage space, and without any convoluted installation, while an external hard drive is the best choice. It not only connects directly to your computer’s ports, but it also conserves all the events you want. Here are some best features that may help you buy an appropriate external hard drive.
How to Buy appropriate External Hard Drives:
Consider the amount of space of your internal hard drive: Before purchasing a new external hard drive, note down the exact space you are using and the average size of the files. Then make clear of the rest physical space on your desk. After drawing the above information, determine which kind of hard drives you really need, a flat one or vertical-standing one.
Make sure that the space of external hard drive is as much as that of the internal hard drive, or even larger: If you want to add more files into the computer at the same rate, like video or computer games, look for the external hard drive with larger storage than your current hard drive.
Data transfer rate of the hard drive: An external hard drive with a data transfer speed of 480 megabytes per second is much better for data transferring with internal hard drive, while some drives may only have the rate of 90 megabytes per second.
Spindle speed of the external hard drive: The spindle speed should be also considered carefully. Since a drive with a spindle speed of 7200 rotations per minute (RPM) is more efficient in saving and modifying data than the one with the speed of 5400 RPM.
Keep accordant between the port and computer connection: Make sure the port of your new external hard drive is accordant with your computer connection -- a USB connection or a Firewire connection.
If there is no appropriate pre-build external hard drive, try to assemble a new one with an internal hard drive, an external drive bay case and a USB cable.
There is one fact that you should know: 1,000 megabytes amounts to one gigabyte and 1,000 gigabytes amounts to one terabyte.
