External Hard Drives Are Handy
External Hard Drives are fast becoming popular as data backups are becoming larger than ever. The amount of data stored on the average computer is climbing, thus increasing the need for backups. External hard disks are an easy and affordable means of backing up a computer system.
An external hard drive is easy to use, since the drive can be written to just like an internal drive. An external disk is relatively inexpensive, especially when compared to traditional data backup solutions. In addition, portable hard drives offer the ability to take data anywhere with you- since the drive only weighs a couple of pounds or even less.
Perhaps the most important specification on a external disk drive is the size of the drive. External drives are typically rated in Gigabytes or GB. When selecting an external hard drive, you should first know what you will most likely be using the drive for, and roughly the amount of data you will be storing on the drive.
Take into account the amount of space on your computer’s internal hard drive. Check the amount of space you are currently using and find out the average size of the files you use. Consider the physical space available on your desk and decide if you want a flat or vertical-standing external hard drive.
Look for an external hard drive that is at least as large as your internal hard drive if you plan to continue adding new files at the same rate. Consider an external hard drive with an even larger capacity than your existing hard drive if you will be using large files, such as videos or computer games.
Consider the data transfer rate of the hard drive. An external hard drive with a data transfer rate of 480 megabytes per second will transfer data to and from your internal hard drive much more quickly than one with a transfer rate of 90 megabytes per second.
Check the spindle speed of the external hard drive. A drive with a spindle speed of 7,200 rotations per minute (RPM) will save and modify data more quickly than one that only has a speed of 5,400 RPM.
