Chip is building a computer and wants to add a new NAS to his Drobo. Leo says that Chip has a DAS, or Direct Attached Storage. So building a NAS would be different. But it's a great time to buy hard drives for it, as WD NAS drives are under $90 right now. DROBO isn't that great as a NAS, because of the software. But as a large drive or direct attached storage, it works. For a NAS, Leo's favorite is SYNOLOGY. He uses the five drive model for his network and then backs that up to the cloud. It also works as a server. Another is QNAP, but that's a bit more expensive.
