External Hard Drive What to Look For?

In older times, owning an external hard drive was a luxury and these devices were not only big, but also needed an external power supply to function.However, now these devices have become so commonly available, that almost everyone has one of these devices which stores gigabytes of their content including photographs and other content.But in case you are looking to buy an external hard drive, following are some points that you should consider.

Disk Space
Whether you buy a pink external hard drive or a brushed steel one, the most important aspect of the external hard drive is the amount of storage space that the disk supports should meet your requirements.The problem is that most people tend to buy a disk, which has much more storage space as compared to their requirement, just because bigger disks are available.While you could get a 2TB external hard disk from Amazon.com or other sources for as less as $120, 2048GB worth of storage space is much higher than the storage requirements of most people.Instead think about how much room you really need and then aim for one the next size up from what you think you need.This will ensure that you do not squander money for buying a disk where most of the storage is not going to be utilized.

Power Supply
You should also consider on how the device gets the power for functioning.A variety of the smaller disks, which store up to 500GB come with the option of using the USB port to meet its power requirements, thus making the device highly portable and convenient.On the other hand, owing to the larger power requirements, the bigger disks typically come with an external power supply, which make it less portable since you need access to a power socket, especially when using it with a laptop.

Software
The different hard drives come with their software suites, which provide some good to have features with the drives.For instance, you have backing up software, which can backup the data on your computer and store it in the external hard drive. Also, the software does incremental backups, to ensure minimal disk space utilization and keeping the data up to date with the main drive.Yet if you backup only select files like I do, then all that fancy software gets in the way, and it is usually installed on the drive so you can't get rid of it too.

You can find out most of this information by simply looking online at websites like Amazon.com, that will give you the specifications for it.Then check out the reviews as well to see what other people think about the reliability of the unit and how useful the software actually is etc.
