| The Bottom Line | The second-generation Drobo adds a FireWire 800 connection, but the original USB-only on the now discounted Drobo might be the best bet for Windows users until better FireWire 800 drivers arrive. The device remains the most automated and easy-to-use redundant backup product we've seen. | The second-generation Drobo adds a FireWire 800 connection, but the original USB-only on the now discounted Drobo might be the best bet for Windows users until better FireWire 800 drivers arrive. The device remains the most automated and easy-to-use redundant backup product we've seen. | Drobo takes the pain and confusion out of data protection and lets you tailor and expand the drive according to your needs. This so-called storage robot works exactly as promised and is the most innovative storage device we've seen in a long time. We want one. | Despite a few shortcomings, the Synology DiskStation DS411slim makes a worthy upgrade from its processor, the best-of-its-time DS409slim. | The WD My Book Thunderbolt Duo makes a very good external storage device for Thunderbolt-enabled Macs thanks to its comparative affordability, ease of use, and decent performance. |
