Query: 3 reasons

The 3 reasons people buy this is for Speed, Ease and Security. The problem is that this unit deliverers none of the 3. Most of the low review here is because of how slow it is. I mistakenly thought it would be more plug and play and easier than networking hard drives on different computers. I thought it would be safe for backing up data... unfortunately it uses a different file system than FAT or NTFS... it's not possible to take out one of the hard drives and put it in another computer or enclosure and read the data.Customer support is the worst I've seen.I still use my NAS200 because I wouldn't feel right selling it to a friend, but I won't trust it with important data. Go buy an external hard drive instead and network it instead.
