Even if you’re not in I.T. I’m sure you realize that having all your important data on a single drive is risky and the way data has a tendency to grow, you never have enough storage.
I recently found out about Drobo which is being touted as the world’s first storage robot. Kinda silly tag line, but the demo is extremely impressive. It’s a four disk enclosure that connects to your system (Windows or Mac) via USB and provides a very flexible and resilient storage volume for all your data. It doesn’t come with any drives but they will accept any SATA drive of any size and will automatically grow the volume and replicate the data while the system still runs. If a drive fails, just pull it out and replace it with one of equal or more size and it will rebuild the array and grow the volume, if possible.
If you watch the demo movie, you’ll get a much better idea of how it works. The downside is that the unit is $499 with no drives. I’ll have to think about it, but may have to start saving pennies.
