Drobo storage devices: beyond RAID

I attended Digital Winter in London this week, an event where gadgets are shown to the press.

One that caught my eye was the Drobo range of storage devices. The market is saturated with external storage solutions, but Drobo has a neat system where you simply slot any 3.5” Sata drive – no drive bracket required – into one of its units and it will add it to a pool of storage. Drobo supports thin provisioning, which means you will typically create a volume on the pool that is bigger than the space actually available. When you are running out of space, a light on the unit will turn yellow, you buy another drive and slot it in. Presuming you have two or more drives, RAID-like resiliency is built in, though Drobo calls its system BeyondRAID because of its greater flexibility. There is even an option for dual disk redundancy, so that any two drives can fail without loss of data.

I was reminded of Microsoft’s new Storage Spaces in Windows Server 8 which offers some similar features, but of course is not yet available except in early preview.

Drobo boxes support USB, FireWire, and in the high-end models iSCSI.

The snag: prices start at €359,00 for the 4 Bay firewire and USB 2.0 model, and the one you really want, the 8-bay DroboPro with iSCSI, is €1359.00. In the business range, the 12-bay iSCSI SAN is €10,799 and supports SAS as well as Sata drives.
