Drobo - it just works
July 8, 2008
I just bought a Drobo to make use of a bunch of old drives I have lying around. I’m a big fan of redundant storage systems but my recent experiences of using an Apple RAID card in my MacPro have been less than satisfactory. The performance was not as good as I’d expected, it takes ages for raid arrays to initialize and I was getting a lot of problems with the system not coming out of sleep so I decided to ditch that.
I ordered the Drobo from Expansys on Thursday and it arrived on Monday. Today I pulled it out of the box and set it up. Firstly, the unboxing is quite a nice experience in itself, comparable to opening an Apple product. The all-black interior of the box, complete with black foam and a good quality black fabric bag on the Drobo itself, all lend an air of quality to the experience. There is a bit, three-step, getting started guide on the cardboard cover and all the cables and accessories are laid out in a separate tray.
So what of the device itself? The unit is smaller than I was expecting, just large enough to take four drives. It has nicely rounded corners and a very solid feel without beeing excessively heave. The front panel is held on by magnets and is removed with a gentle pull to reveal the drive slots. These have spring-loaded flaps on them and inserting drives is simply a matter of sliding them in until they click under the restraining clips. The Drobo takes any combination of SATA1 and SATA2 3.5″ drives. I put in a 750G, two 500Gs and a 250G.
The Resource CD has tools for both OS X and Windows. I was installing on a Mac which was just a matter of running the installer program for the Drobo Dashboard. The Dashboard provides several useful views of the device configuration from the overview:

Following installation, the software offered to upgrade itself to the latest version, which it did with no fuss. Then it asked me to plug in the Drobo USB cable and it set it all up automatically, only pausing to ask if I wanted FAT or Mac OS Extended format. Within about two minutes I was up and running with 1.1TB of free space, all fully redundant spread across the 2TB of drives (1.8TB actually usable). This is far more impressive than the half-hour or more it usually takes to fully initialize a RAID array.
All in all, I’m very impressed with the device and the setup. The next test is how well it performs. Clearly the USB 2.0 connection will be a limiting factor here, but I’ll keep an eye on it to see how it goes.
Update:
Mind you, given this announcement, perhaps my timing for buying one was not so great.
