The option of expanding memory storage using external drives becomes extremely useful when you are running out of storage space in your computer. A USB hard disk is the easiest type of hard disk drive extension - all you have to do is plug in the drive to your USB port and copy over any data you want to store in the new hard disk drive.
With the invention of portable external hard drives, the tedious and often awkward task of opening a computer case and adding a new drive, then configuring it to run with your particular machine, is no longer needed. You can carry the USB drive wherever you go and access that data stored in the drive on any PC.
A USB hard disk is a drive based on standard EIDE. The hard drive has an exterior closure which has a USB interface and you can connect this drive to your computer using a standard USB port. USB hard disks of various sizes are now found in the market. You can buy as much as a 1TB disk or more - or as small as a 4GB disk. People who want extra storage space are now looking forward to buying standard 250GB hard disks that are available for less than $150.
Using an external hard disk, you can backup all your important data and make sure that you never lose an important file. The whole hard disk system stays outside your computer and it comes with a hard casing that protects disk platters inside. Some larger hard drives come with a separate cooling fan that cools the system. The USB hard disk drive can take power from your computer itself and therefore, there is no need for any additional power source. High speed cables are used to connect the hard disk drive to the computer to enable fast data transfer. If you are more concerned about speed than cost, a Firewire hard disk could be a good option worth looking at.
When you buy brand name hard disk drives from Western Digital, LaCie and others, you can enjoy plug and play hard disk drives. Once your computer’s USB port is ready to accept incoming connections, you can simply plug the USB hard disk and use it. Some large hard drives require you to create partitions that can be useful for managing data storing. Just like accessing a hard disk already installed in your computer, you can utilize your USB hard drive in just the same way. No other additional steps are required.
Modern day USB hard disks come with backup programs that help you to back up your existing computer hard disk drive. With this type of useful software, you don’t have to manually copy the files you want to backup. A duplicated hard disk drive is always a safe bet because if/when your primary hard disk drive fails you can always use the external hard drive to restore the original data. Furthermore, USB drives are portable and they can be used with multiple computers. Many people use USB drives as a data transport device to transfer data between compatible computers. You can also use the external hard disk drive as a network storage device and share it with other users in the network.

If you had to choose between a Seagate, Western Digital, or a Samsung hard drive, which would it be? Which do you consider the most reliable out of them? I had a WD that went to crap on me after about 6 months, so I’m a bit leery of them.
