Product Description

Drobo 5N 5-Drive Network Attached Storage (NAS) Array, Gigabit Ethernet

The Drobo 5N was designed to deliver the best file sharing experience available. From the moment you open the box, you’ll know there’s nothing like it. It’s perfect for any connected home, home office, or business environment that needs simple, safe storage for sharing and backing up data over the network. Not only is the Drobo 5N fast, but also easy-to-use, expandable, and automatically protects against hard drive failure(s). It’s perfect for storing large collections of photos, movies, music and documents and integration with Apple Time Machine makes it an excellent way to back up all your Macs to a single device.

All Your Stuff, Automatically Safe
SSD acceleration boosts performance up to 10x
Designed with You in Mind

Drobo storage arrays have always been designed with the user in mind. From the tool less design that allows hard drives to be inserted without carriers or screws to the variable-speed cooling fan, the compact and quiet 5N was designed to work just as well on your desk as it does in an office environment. Users can also dim the lights and configure drives to spin down when not in use.

All Your Stuff, Automatically Safe

Built on award-winning BeyondRAID technology with single or dual-drive redundancy, Drobo 5N protects your data without any user interaction. Drives can be added or replaced on-the-fly for storage expansion with zero downtime. If you're running low on space, the lights on the front tell you what to do. Just add a drive in an empty slot or remove a smaller drive and replace it with a larger one.

High-Speed Gigabit Connectivity

The Drobo 5N is equipped with high-speed Gigabit Ethernet and connects directly to your network to make sharing your data easy. Just plug it into any switch or wireless router and you're ready to go. You can even connect the Drobo 5N directly to the Ethernet port on your computer without having to configure any settings.

SSD Acceleration Boosts Performance up to 10X

Most storage arrays use either all hard drives or all SSDs. The Drobo 5N delivers the best of both worlds by intelligently combining hard drives and SSDs to deliver both capacity and performance. Using a small form-factor SSD boosts performance of popular applications such as Apple iPhoto and Adobe Lightroom by up to 10X!

High-Speed Gigabit Connectivity
Power Protecting Your Critical Data

Drobo doesn’t just protect your critical data from drive failure, but also from power outages. The Drobo 5N includes a battery that protects all data--whether active or at rest. Should the power go out while using your Drobo, the battery will protect everything until the power is restored. The battery recharges automatically and is designed to last for the entire life of the product.

  • Highly scalable network storage array
  • Gigabit Ethernet connectivity
  • Holds up to 5x 3.5” SATA HDDs
  • Optional mSATA SSD boosts performance up to 10X
  • Award-winning BeyondRAID automated data protection

A swish looking device; will look a peach beside an imac. Set-up is easypeasy: plonked in 5 WD greens (3TB), and all Go within 15mins or less. I use the drobo to hold all iTunes media, and it does this job well; streaming music and video works well. Read (for me) is around 100-117MB (at the top end, with no SSD), while Write is 98MB (at the very top end - cannot get higher than this on my setup: gigabit, with no jumbo frames (which made no difference activating, in my opinion).


-you can pop in 5 drives, all at once (even this populated with data).
-push the drives in firmly; one of mine was a little loose, and rattled a little as a result.
-the fan does make noise, and will be loader than that on the late 2012 iMacs; however, the whole unit is quiet in compassion to a Samsung external blu-ray reader/writer. The fan is variable, so do not be alarmed if the tempo changes - you will have to get used to having a hum/whirl in your office if you leave it on 24/7
-support (from Germany, in my case) is prompt, and efficient.
-it takes some time for the drobo dashboard to find the drobo: wait for it.
-WD greens are CAN be used, but drobo does recommend, say, WD Reds as these are designed for a 5-bay NAS environment, so go with NAS drives rather that Greens; i just has mine already or i would have gone with those recommended.
-an SSD can be put into this drive, and it would be interesting to see if performance increases in such as way that would make the expense worthwhile
- there are not many reviews around of these device (lots of the 5D model), but you can get people-views (as i term them) from (not
- Do a google price comparison

I have had the device for some 2-3 days, so i may make an update to this review latter

Further, drive spin-down works a treat; the devices usually does spindown after, say, my imac has gone to sleep. You can, of course, shutdown the device.

This is my second Drobo and clearly there has been a measure of progress since my earlier, second-generation model. However the new Dashboard software didn't even recognise the old Drobo.

It is, however, disturbing to find that Technical Support know nothing of my earlier model, a mere four years old. And the bottom line with regard to that one is that none of the disks, two of them dating back four years, has failed, but the machine itself has now died. Raid or no raid, the fact is that there's a single point of failure and the material is unrecoverable -- though mercifully I spooled it off when the older Drobo began to become flaky.

If you're not short of cash, buy two of them and use one to mirror the other. Otherwise a couple of external hard drives may be much better value for money.

I bought a Drobo 5n a few years ago after I saw an advert for it. To be fair on the product, it worked okay for the first 2 years without issue until one day recently when it suddenly stopped working without warning and I found I could not access any of the data on it. Suspecting faulty cables, I tried a new set but the unit still would not work suggesting an internal power failure. Fearing loss of data I took the drives out and had the data on the disks professionally recovered which took several weeks although the Drobo unit itself no longer functions.

I have a colleague who also bought a Drobo 5n which failed in a similar way. Consequently, I would offer a warning to potential buyers that the Drobo should not be considered entirely dependable. I certainly won't be buying another one as I found Drobo's after-sales technical support most unhelpful. It seems that after you purchase one of these things, Drobo Inc. don't want anything more to do with you.

I make a further recommendation that if you are intending using a Drobo as your primary back-up device, be sure to have a secondary back-up system in case the Drobo fails like mine did.

This is my first NAS and setting it up was a breeze.

However, actually using it has been slightly frustrating. I'm an Apple user and not particularly techy, so wanted something simple and intuitive - a bit like Apple, really!

Installing the software? Easy.
Drives? Easy too.
Time machine? Done.

Then I tried copying my media files and documents across from my WD 4TB thunderbolt duo (full) and it all started to unravel a bit. Whether connected to the Mac via the network or directly wired in, the file transfer using finder hung regularly, giving a "-50 error" - I felt like I was using DOS again. Anyway, it appeared to be related to the number of files being transferred simultaneously. 5 or so 1-2GB films at a time was OK. Now that they're all across, it is working fantastically, but this initial population of the NAS was a pain.

I contacted Drobo, who said it was a problem with Mac OS, as other NAS systems have reported similar problems... I'm a bit surprised to hear that, but anyway. Irritatingly, my work laptop running Windows 7 seemed to work fine.

Anyway, that's the only reason I gave 4 rather than 5 stars. I hope my comments are useful to you.

I've been toying for years with the idea of buying or building a NAS. Mainly for backups but also because I have a number of devices which could really use the documents I had stored on one machine (e.g. iTunes library, DVD rips etc).

Ease of use

The main reason I decided on the Drobo 5N is because I don't have to worry about setting up and handling a RAID, and because I can mix and match drives. Installing drives is a breeze too - I had my girlfriend install one hoping to help convince her I hadn't wasted my money (she wasn't interested). The Drobo Dashboard app is easy to use, though it can be a little slow at times which is frustrating but I'm just impatient. Installing Drobo Apps on to the device is simple click of a button.


I've set my Drobo up to use single drive redundancy, but you can use dual drive redundancy if you like. I've only had it a short while and no drives have gone belly up yet so I haven't had the experience of how well the Drobo handles it. It works without hesitation across multiple protocols on different OS (I've tested OS X, Windows 7 and iOS). The Drobo Apps are great, I use Plex to provide a media center server. Caution that you will probably need to encode your files because the Drobo doesn't really have the power to transcode on the fly.


There are plenty of other reviews and YouTube videos detailing the performance, so I'll not go into too much depth. What I will say is I get a constant 70MB/s when copying data to the Drobo - both wired and wireless. It wasn't nearly half as painful to transfer 3TB of data as I thought it would be. I've installed an mSATA SSD which is supposed to improve speed of 'hot' files, I can't say I've noticed too much.
