Louis has a first generation Mac Pro and he's thinking of getting a new Mac Mini instead. He has a few extra hard drives, and is wondering how he could use them as external storage. Should he get a Drobo? Leo says that Drobo's tend to be a bit pricey and overkill for the average person. It's for multiple drives for data redunancy.
The easiest thing he could do is to buy an external USB 3 enclosure and use it that way. Another option is Synology. A good project would be to take that old Mac Pro and turn it into Network attached storage (NAS) itself.
