Data Robotics Drobo Review
About a month ago, I bought a Drobo to expand my hard disk storage. Normally you would buy an additional hard disk to add storage. Problem with that is that those drives will eventually fill up with all sorts of important information.
Every time you add or replace disk you need to move data around, which takes a lot of time.
The Drobo is an external enclosure which holds up to 4 SATA disk drives. The enclosure can be connected via FireWire800 or USB2.0, and is seen by the OS as a removable drive.
Your data stored on the drobo is secured when you use 2 or more drives. 1 disk drive is used for redundancy. So if one drive fails your data is still there.
