Anyone that has ever looked inside one of these “drives” will realise that they are only suitable for temporary storage capacity. There is nothing magical inside the enclosures, just a couple of standard hard drives and a small RAID 0 controller. What people (ie. general users) tend to do with a drive of this capacity is copy over all of the big data (pictures, movies and music) from their desktop or laptop computer and then delete it from the original location to save space. Not only is this not a backup but the chances of this drive failing are more than doubled due to the fact that the data is striped across two drives, either of which could fail at any time. In a RAID 0 only one drive needs to fail to take out all of the data.
One terabyte drive fails = 2TB of data gone!
Anyone thinking of using one of these should consider buying two and using software to mirror them. At least you would have some redundancy. There are of course much easier and not to mention cheaper ways to set up a redundant backup solution. We will post a more detailed guide of how to do this in the near future.
