I have massive libraries for which I need a backup. As for the Time Machine backups of my Macs. The Drobo does the job perfectly! It is quiet, very easy to use and offers the usual performance that can be achieved in a Gigabit network, ie for large files almost to the 100 Mbit / s and at extremely many small files, it is quite slow. But this is at other NAS exactly the same. Direct Attached Storage is always faster. One of the same mitbestellten WD showed SMART problems and was replaced by Amazon easily. Since the Drobo was already in operation, I came to enjoy the automatic reconstruction: broken plate out - new pure - done!
The Drobo provides far less gadgets than Synology products but for my purposes the ideal solution.
