With the way that most companies are promoting digital media and digital downloading, having a hard drive with a ton of storage space is very important, especially for people who love to download movies and games. But sometimes having a single hard drive within the computer just isn’t enough. That’s why external hard drives have gotten very popular the past few years. External hard drives are a great way to store and backup your data while still being able to save space on your computer’s internal hard drive.

Why External?

Why not? Having an external hard drive benefits you in the long run, especially if you’re the kind of computer user who keeps his computer for many years. All the GBs in your hard drive will eventually be filled, so having an extra hard drive you can take outside of the computer is great for having more storage which means more downloading to your heart’s content.

Types of External Hard Drives

There is more than one type of external hard drive. They all perform the same basic task, but there are also a few key difference with these drives depending on how often you intend to use them and for what types of computers these drives will be going towards. The types of external hard drives you can choose from are:

  • Portable Hard Drives
  • Desktop Drives
  • Multiple Hard Drives

Portable Hard Drives

Portable hard drives are what you expect them to be. They are smaller, more compact versions of external hard drives best used for laptop computers. The hard drives are powered by USB or FireWire cables. It used to be that these portable versions were weaker and had less storage space than the desktop versions. However, newer and better portable hard drives are being made and some of the newer ones can store up to 500GB of data easily. That’s more than standard internal hard drives!

Desktop Drives

These are the external hard drives you know and read about. They’re much larger than the portable versions, and because of this require much more power. Often there is an AC adapter that comes with the hard drive to give it enough juice. These hard drives are the kings of storage. They can hold 1 and terabyte of data. That’s 1000GB! Now the standard internal hard drive is starting to look pretty minuscule in size.

Multiple Hard Drives (Multidrives)

And if you thought that was impressive, imagine more than one of those external hard drives put together. These multiple hard drives pack a ton of storage and can hold 2 to 3 terabytes at a time. You could probably own these things for years and never completely fill them. One of the best features of multiple hard drives is that they also contain RAID storage, a feature that allows you to protect your data and create a backup by duplicating everything. That way if your internal hard drive or one of the external hard drives fail, you still have the backup ready to go.
