Dell: Automatically Protecting Your Data

Today Dell is unveiling a new data protection hardware feature, available on select Dell computer systems, which will ensure that you won’t lose data due to hard disk failure. Of course if you regularly back up your data, that won’t be a problem in any case.
The Associated Press writes For $99, consumers get a second, 80-gigabyte hard drive inside the computer which acts as a mirror, continually backing up data on the primary drive. Larger disk sizes are planned.
While consumers could conceivably buy an extra hard drive and third-party software and do the same thing, the idea was to make it simple for consumers, spokesman Liem Nguyen said.

If you are ordering new Dell computers I would HIGHLY suggest you request this option.
Lenovo’s ThinkVantage Technology offers similar and more protection as well.[end post]
