we're smitten with Drobo's storage "robots." But they're expensive, especially compared to direct-attached or NAS storage devices built on a traditional RAID architecture. But if price is holding you back then you'll be happy to hear that for a limited time, you can take 20% off the list price of the 4-bay array. If you're lucky, you already have a handful of loose drives to plug-in else why not stuff it to capacity for 8TB of disk this Father's Day? Granted, still no built-in Ethernet without the optional DroboShare, but at least you've got an extra paper hundie to dry your tears.
