| The Bottom Line | 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. | The My Book Studio Edition II makes a decent direct-attached storage solution for those who need to extend a computer's storage space or want a large backup drive. The drive's rather buggy firmware might turn many users away, however. | 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. | If you have a Thunderbolt-enabled computer, the Promise Pegasus R6's storage capacity, its features, and especially its performance are worth the hefty investment for those who demand fast external storage. | The My Book Studio Edition II makes a decent direct-attached storage solution for those who need to extend a computer's storage space or want a large backup drive. The drive's rather buggy firmware might turn many users away, however. |
