I stumbled across this in good timing since I'm considering this solution. I recently lost a hard drive and I'm so tired of researching what's best, etc, etc. It seems like for every person who loves XYZ drive, another hates it. I always read that every drive fails eventually, so this may be just what I'm looking for.
Some Details....
Data Robotics today gave its Drobo storage robot an often-requested update with an upgraded model that adds dual FireWire 800 ports to the existing model. The extra bandwidth allows a Drobo with more than one drive to potentially transfer data far faster than the existing USB 2.0 connection (up to 50MB read, 35MB write) while providing a free port to daisy-chain other devices.
The four-bay robot also has a better processor to improve shuffling data between drives as it creates its automatic redundant backups, or else out to an attached computer. Data Robotics is using the new model as a direct replacement and ships it for $499 with all of the Serial ATA bays empty; versions preloaded with 2TB or 4TB of disks sell for $899 and $1,299 respectively.
Original USB-only Drobos are being cleared out at $349 for an empty model, $749 for a 2TB model, and $1,075 for a fully-laden 4TB model.
