External hard drives are proving to be one of the fastest selling computer accessories in the market at the minute. Even though they have been around for many years, people didn´t really recognise how important external hard drives are and how many benefits they can give you. But you only have to have one computer malfunction due to a virus or other factor to know that investing in an external hard drive before the inevitable happens will save you a lot of time, frustration and heartache. Take a look at why investing in an external hard drive has many benefits.

External Hard Drive Backup
A hard drives greatest benefit is for backup. It´s the most obvious reason to buy an external hard drive, but is also the most important especially if you use your desktop computer or laptop for work purposes. Investing in an external hard drive on which you can back up all your data will save you an absolute fortune in time and money having to redo lost files because your system has crashed or your files were corrupted by a virus which caused the data to be irretrievable.
But it´s not only professionals who will benefit by backing-up data on an external hard drive. Just about everybody today downloads their photographs straight from their cameras on to their computer systems. Imagine how you would feel if you lost years worth of holiday snaps and memorabilia shots of your children growing up. That´s right, gutted! So don´t take the risk.
Security
Another great advantage that an external hard drive will give you is security. Providing you don´t constantly keep your external hard drive plugged into your computer turned on you can safely back up your files from your computer without the risk of it being attacked from malicious malware or other viruses that are fed by predators through the Internet. The best way to use an external hard drive is to back up your data at the end of the day, or just after you have loaded some important material to your computer, and then either unplug it from your system totally or simply turn it off.
Portability
Because they are small, compact and light-weight, external hard drives can easily be carried around with you allowing you to save information from one computer and retrieve it from another machine. This is very useful for professionals who take their work home with them and use different a different machine in the office, or if you want to share files, such as holiday photographs and music, with a friend. Simply save them to your external hard drive, pop it in your bag and laugh at your white bits over a bottle of wine. One thing you should consider when carrying your external hard drive around with you however is that they can be quite fragile so keep it secure and don´t let it be bashed around where it is more vulnerable to breaking.

Hard Drives with Excessive Memory
External hard drives are available with lots of memory, some up to 1TB, thus they can be used for a number of reasons. Say you watch a lot of films and download streams from sources like UTorrent. Your computer memory can only hold so much before it runs out of room; therefore you can save and store them on your external hard drive and free space up on the built-in hard drive of your computer which allows you to download new films and music. External hard drives effectively become your portable media library.
