Taken from: The Main Benefit of Data Encryption - Learn Why Data Encryption is Important for Your Laptop
The main benefit of data encryption is that even if you were to lose your computer, get malicious malware or are hacked, the data inside your computer is still safe. Encryption of data gives you one last saving grace, the data may no longer be in your hands, but no one else can see it or use it.
Now, you may be asking, what are the chances that you'll lose your data? It can't be that simple can it?
One last subject to touch on is the encryption of data in smartphones. In today's busy world, many people keep sensitive, important information in their smartphones. Do you have a corporate smartphone, or a personal smartphone? Do you have your company e-mail sent and stored in your smartphone? Do you use the store password option in your browser on your smartphone?
Smartphones such as the Apple iPhone, HTC HD2, Motorola Droid, and others are widely used like computers. The lines between smartphones and computers are blurring, and the amount of unprotected data is smartphones is always rising. Data encryption is just as important on smartphones in case you lose your phone or have it stolen. There is software available that you can download onto your smartphone that will encrypt your data.
Encryption of data on a smartphone works the same way as encryption of data on a computer. Someone needs the key to decrypt the data and steal it. The worst case scenario is that the person fails at hacking your phone and ends up wiping it clean for their own use. You may have lost a few hundred dollars but at least your identity is safe, your computer information is safe, and any other data is safe.

Encryption adds an extra layer of security to help you feel at ease, even if your laptop is stolen, your smartphone drops out of your pocket, or your anti-malware software eventually detects that malicious software is snooping through your computer. Encrypted data is worthless to a hacker, and you've effectively made them waste their time and effort to achieve very little. The most you lose is your hardware, but the most important aspect, the data is still well protected.
Encryption of data can be annoying at times and cumbersome for some, but it is the last stand in protecting your data. When all other security measures fail and your data ends up in the wrong hands, encryption is the last piece of security standing guard.
