It’s an unfortunate fact that hard disk drives are rather slow at storing and retrieving data. Due to their mechanical nature they can only retrieve and send data to the controller at a certain speed. Many users now opt for an external hard drive as a supplement – big mistake if you are storing a lot of critical data, such as client files etc.
Hard disks are mechanical devices with moving parts, and as such will break down eventually, compromising any data stored on them that is not backed up. External drives are likely to break down much quicker. One technology that was developed to deal specifically with this issue and deal with this is a RAID data recovery drive (Redundant Array of Inexpensive Disks).
