Wow, that title's a mouthful -- Network Storage Array -- but don't let that technical-jargony sounding term scare you, this Drobo FS device is really as easy to use as your Fridge. And for me, that's a Holy Grail -- something that you use and basically forget the complexity.
 
Whut? 
But let me back up a moment and describe what a Network Storage Array (or NAS - Network Attached Storage) device is.

 
Basically, it's a box with a bunch of hard drives in it, and some network intelligence. You connect your NAS to your home or office network, and it appears to your computers as if it's another computer on your network that's sharing some drives.
 
You copy stuff to your NAS and share files with any other computer on your network.

 
Pretty simple, yet difficult to do well 

And this is where things get a little squirrely. Some people have a household with mixed computers sharing the same network. In my case, I've got Windows (2 varieties), OSX and Linux machines. And some network storage devices don't play well with different machines on the same network. Sure, the box may say Win/Mac, but invariably issues arise. Not so with the Drobo FS.

It's a sleek, black, Fridge 
The Drobo FS unit I tested for this review was a 5 bay unit. In it, I installed 3 different sized drives to use for my network storage, not something you normally do in most NAS devices.

And also unlike most other NAS devices, Drobo doesn't use standard RAID technology to manage your data. Instead, they use a proprietary combination of hardware and software tools called BeyondRAID.
 
At the risk of oversimplifying, all the drives you mount in the Drobo FS are merged and are available as one big pool of data storage. Each physical drive loses its unique identity as far as anyone on your network is concerned.

BeyondRAID works behind the scenes, managing the file storage and maintenance. To start to use this storage space, all you do is log into the Drobo Dashboard to create virtual drives visible to your network.
 
Smart, safe, and accessible 
One of the reasons you use a network storage device is to have a safe and reliably managed location to store important data.
 
The Drobo FS device keeps the data safe by a little technical wizardry. Remember what I said previously about all the drive space being pooled? Well you don't get all of it to use for your storage.
 
A Drobo FS device using BeyondRAID needs a certain amount of that drive space for 'overhead'. This overhead is what keeps your data safe from physical hard drive failures.
 
One drive goes bad, and the Drobo FS lets you know about it, but your data is safe. Simply swap out the bad drive for a good new drive, and after the unit integrates the drive to the pool, you've got all your additional drive space back, without an interruption in work due to a down drive or server.
 
There's even a Dual Drive mode that will let you recover from two drives failing at the same time.

In my case, the drives I'd mounted totalled about 4.5 TB, which actually means that with the BeyondRAID data security system I've got about 2.24 TB available for data. Depending on your drive configuration, the percentage available for data can vary. Drobo has a cool Capacity Calculator on their site to help you see how the device would work for your data storage needs.

I'm storing all my photos and personal videos on the Drobo FS, as well as my music and video collection. By having that data available on my network, I can view the photos or movies from any of my computers, or other network-aware devices such my Blu-Ray player or media centre. And that irreplaceable data is much better protected than if it was just on a single drive on your computer.
 
Friendly technical assistance 
In the course of preparing this review, I did run into one issue with the Drobo FS. One day the device didn't want to talk to the Drobo Dashboard application, either on my PC or OSX machines. I could still connect to the drives hosted by the Drobo FS, but the Dashboard software was dead in the water.
 
The solution it seemed, was a simple power down / power up of the Drobo FS, but before I got to that solution, I contacted their Technical Support department via email and was promptly and confidently led through a set of steps to troubleshoot the issue.  Once we got to the power down / up step, everything was back to normal, and it’s been normal in the weeks since.
 
It's a Time Machine 
More tech issues; just as I was wrapping up this review, my wife's new Macbook Pro decided to get a little wonky -- audio cut out completely and there was an issue with the Boot Camp drive deciding it really wanted to be the only OS on the Mac. So it went back and she received a new replacement. Cool.
 
But what was really cool was the Time Machine backup we'd done to the Drobo FS, previous to taking the Mac in.

To use Time Machine on network drives, you have to set up a special virtual drive. On the Drobo FS, it was a simple as creating a new virtual drive and checking a box to set that share to be usable by Time Machine over the network. Once that's set up, Time Machine settings on the Mac will automatically make intelligent backups of your Mac according to whatever schedule you set.
 
And it was this backup that saved us hours of reinstalling software from disc, Steam or the app store.
 
So? 
It worked as expected. That may sound merely adaquate, but I've found that working with new tech has often had a few surprises in store through the setup and install process.
 
In this case, my experience with the unit and Drobo tech support was top-notch. The printed documentation, the setup process and the daily operation were all as I expected.
 
And if you’re a bit more technically advanced, the Drobo FS has the ability to run DroboApps -- small useful utilities such as an Apache web server, torrent client or Media Centre application. Full details on DroboApps here.
 
My take? The Drobo FS is a data storage appliance, deceptivly simple from the outside, reliable and solid on the inside... and it rocks!

I've been on Drobo for quite a few years now.  Love it.  Bought a second one last year when my videos and pictures filled up the first.

 

For who haven't seen it.... check out this demo video that shows it's simplicity.... http://www.youtube.com/watch?v=05yqvb5n36M.  Just plug and forget it.

 

There is only one negative thing about Drobo.... the cost of DroboCare.... After purchasing an item, I expect to get software updates FREE.  Drobo only offers updates for 1 year.  After that costs add up for their subscription service.... http://www.drobo.com/support/drobocare.php.  I still recommend Drobo because it's very hard to put a price on data protection.

 

Just remembered..... the magnetic front cover is held by magnets.  It buzzes from the spinning hard drives.  Make sure it's seated properly.

 

One other thing.... have you ever tried to restore a 2tb drive on Drobo?   It can take days....

@XL - Do you have any idea how much the harddrives are pricewse? Couldn't find them on the FS website. I'm interested in this.

Future Shop internal drives are found here... http://www.futureshop.ca/en-CA/category/internal-hard-drives/10484.aspx

 

To clarify... Drobo is not a hard drive.  It's an enclosure.... Oh look... Future Shop now sells these data gods....

A few other tips....

-I think today's hard drive sweet spot is 2tb.  This is what I buy for my Drobo's.

-I have had bad luck with Western Digital's EARS series on Drobo.  The WD EARS drives appear to be fine at the beginning, but I've had Drobo boot up issues with the EARS drives as the drives started to fill up.  Once I swap them for EADS, the Drobo worked fine.

 

Perhaps someone who knows more about hard drives can share more about WD "EARS" drives.  I understand EARS drives uses a larger block size and it created issues.  Drobo might have firmware fixes, but I haven't had time to explore the problem.  My data is too precious to experiment with.

 

I'm not particular to any hard drive brand.  I have Western Digital, Seagate, and Hitatchi....  I just buy whatever is on sale.  Drobo takes care of the rest.  If a brand or model fails, by using an assortment of brands and models I'm less vulnerable.

Great comments and additional info, esp on the HD sweetspot. I played around with the drive space calculator and noticed different drive configs give better (or worse) free storage space scenarios.

 

@XL -- I thought the dashboard updates and firmware updates were available here (http://www.drobo.com/support/updates.php) at no charge...is there something I've missed?

To clarify, 2tb is my recommended hard drive "price" sweet spot.  I'm kinda dated on my prices from last summer, so I think we can go for a little bigger drives.

 

I just clicked on your support/updates link.... I got an error.  I guess you are signed into Drobo's website for that link to work.  The question is whether those updates will still be available to you AFTER 1yr if you don't have a DroboCare subscription.

 

Then again, the DroboCare prices are US funds.  The Canadian prices were much higher a few years back.

@XL: my bad -- the link above included the closing bracket -- I should have checked. This link should work fine: http://www.drobo.com/support/updates.php

OK....I boo-booed too....  rereading the DroboCare program....

 

DroboCare appears to be an extended warranty and phone support program. You're right.... updates don't require DroboCare.

In regards to this one here... http://www.futureshop.ca/en-CA/product/data-robotics-drobo-pro-8-bay-iscsi-firewire-usb-external-sto...

 

the 1500$ behemoth... it says up to 16 TB of memory, Am i to assume that means 8 x 2TB slots?

by Exalted Expert / Community Ambassador on 04-27-2011 11:40 PM

Don't forget some of that 16TB is going to redundacy.  Check out the DroboPro calculator for a better answer....

http://www.drobo.com/calculator/8-bay/index.php

 

The 16tb specs is based on loading it with 3tb drives with some of that space going to redundacy.
