When I was dealing with tape the main problem was that the drives were very expensive, and they never lasted as long as their expense would have you hope. They have a complex exposed mechanism full of fairly fragile tiny plastic parts.
And for long term archive storage, the main problem is not the media, it is how are you going to read the media. With the drives being considerably more fragile that the tapes. A good plan is to store an entire spare restoration kit with the media. With the understanding it probably will not work when it needs to. So store the really critical stuff printed out so the mark one eyeball can parse it.
