The safe, expandable Drobo storage solution protects your data against a hard drive crash, yet can expand dynamically at any time in just seconds. With nothing to configure or manage, Drobo is now the ideal solution for primary storage as well as backup.

Inside every Drobo is the revolutionary BeyondRAID storage technology that protects data against a hard disk crash, yet is simple enough for anyone to use. As long as you have more than a single disk in Drobo, all data on Drobo is safe no matter which hard disk fails. There's no need to worry about anything else.

Incomparable Expandability
Incomparable Expandability

Your library of data grows every moment and now your storage solution expands in seconds too. Drobo holds up to four hard drives, can expand at any time, and supports up to 16TB on a single volume as disk sizes increase. Choose how big you want your Drobo today with any combination of drives capacities. Yes, you can mix and match drive sizes. Check out the Drobo Capacity Calculator to try it out for yourself.

Protection from a Drive Failure
Protection from a Drive Failure

Protecting your data from a hard drive failure can be a challenging task. Not with Drobo. As long as Drobo has two hard drives, it protects you from a drive failure. If a drive happens to fail, you do not lose access to data, which means that you can keep on working. Just swap out the failed hard drive and replace it with a new SATA drive of any size.

FireWire 800 and USB 2.0

It's the perfect solution for both primary and backup storage of large media and productivity files such as video, photos, music, audio, and troves of documents and spreadsheets. FireWire and USB cables are even included.

Normally I don't write reviews for all of the products I buy, but based on the bad reviews that people have given the drobo, I felt I needed to offset some of the unfair & misleading comments.

I have had this drobo for about a month. I have had very little interaction with the drobo itself. That is becouse once it is set up you forget it. That is wonderful for this kind of storage device.

It really is as simple as putting the drives in, install the software, and begin using it. I first saw this at Macworld in January 2008, but held out for the firewire version. I am using on a mixed environment network with no compatibility problems. It is very fast, and very easy. I am using mine for all of my videos streamed to our TVs. IT ABSOLUTELY WORKS WONDERFULLY! It can simultaniously stream mp4 videos to 2 TVs while having data copied to it.... all without any hiccups. That is impressive for a device like this.

For those of you have have read (or are about to read) some of the negative reviews here, allow me to comment on them:

First complaint: Add (4) 1TB Drives - only get 2.7TB of useable data space. There are two reasons why. First the equivalent of the largest drive is being used incase or drive failure or to be able to do drive expansion.

Second, the device says that you can put up to 16tb of storage in it. This means that WHEN 4tb drives are available, you can put up to 4 of them in this device. Does that mean that you will have 16tb of useable storage. NO. Why? Becouse hard drives are sold based on an inaccurate counting system.

While EVERY SINGLE HARD DRIVE MAKER (or company selling storage space) counts how much space you have based on 1gb =1000mb, this is totally false! The truth is that 1gb = 1024mb.

I own both 1st and 2nd gen drobos, so I can do direct A-B comparisons. Note that I've set up both models with the identical hard drives: 3x 1TB WD green 5400rpm. These hard drives are ideal for the drobo: They are plenty fast enough, but spin at 5400 rpm and so are quieter, consume less power, and produce less heat than typical 7200 rpm drives. (Putting 7200 rpm drives in a drobo is pointless.)

The drobo has so far done everything it is supposed to do. I've even yanked out a drive when it's turn on to test the raid rebuild. It rebuilt fine, and I lost no data. The rebuilt on a 2TB volume took almost 1 day, but it did work.

Apart from the slow speed of USB and even Firewire compared to in internal raid array (which is something a lot of people complain about unfairly, since it is not data robotics' fault!), I have just one complaint: The device is loud. Don't believe their marketing materials that say that the 2nd gen drobo is quieter and cooler than the 1st gen. They don't provide any dB measurements, or anything quantitative. I can tell you, qualitatively, that both 1st and 2nd gen drobos are quite loud. The appear to use the same crappy fan, which is probably the culprit. When the fan is off, even with all drives working, the device is silent (those wonderful WD green drives are soooo quiet). But as soon as the fan turns on, the fan noise is annoying. I may be forced to void my warrantee by spending $20 on a proper fan. Whey didn't they fix this problem in the 2nd gen model? It seems like a big mistake to me.

If you aren't putting this device in a quiet room, then I have only positive things to say (so far!). If you're putting it in a quiet room, then it'll probably work but will probably annoy you a bit.

See note at bottom for update to the story here. Drobo CO did come through and get our data restored. I am impressed by that.


I will revise this review later if story turns out to be anything other than what it now appears to be. We use a Drobo as main disk array for Apple Mac that we use for video editing.

Everything has worked fine for about 6 months. We have Drobo loaded with 4 WD 1,000GB drives. Everything is top notch equipment, with very strong surge protection and uninterruptable power supply, top of the line Apple computer. Okay, that's background.

The other day, Drobo stopped booting correctly. Called Drobo, and they nicely sent us another unit. Same problem. Now they are saying to run certain software to further diagnose. Problem is that drives have to be recognized of course to run that software. It appears at present that something catastrophic happened in the Drobo unit that caused all four of these new 1,000GB WD drives to fail at the same time.

We are now investigating which company to send them to in order to try to get the data off of the platters themselves. Once we have our data back, if we ever have our data back, and we buy new drives, what are the odds that they are going back into a Drobo unit? We will now spend hundreds of dollars to try to recover what we can at the platter level.

The Drobo techs have been nice enough, but they act like this is some problem of ours other than a major failure of their device. Which I guess means it IS a problem of ours, to fix.

Update number one: There will be more. We had our computer tech expert come over and check everything that we have checked and that the Drobo techs had us check.
