oh boy... crappy Maxtor drives inside a box... The unit might be good if you replace the drives with Seagates. Otherwise expect data loss within a year... or right after the warranty runs out.
Hmmm. The final page of the review states that there is not FLASH memory in the thing. This means that it boots from the hard drive. As a result, you cannot replace a drive when one dies, as the operating system will be toast too.
I guess that means that this thing is meant to be disposable when a drive fails. You cannot even open it to replace a drive without breaking it.
