The Data Robotics Drobo 4-Bay Hard Drive Array Enclosure delivers an expandable solution for creative professions and small businesses in need of high performance backup storage. Built on BeyondRAID technology with single drive redundancy, the Drobo protects your data automatically, even in the event of multiple drive failures. Able to hold up to four hot-swappable drives, this system ensures you'll have a high-performance connection to virtually any system with available USB 2.0 and FireWire 800 connectivity. With its unique ability to mix and match drives of several different classifications, the Drobo allows you to instantly expand your capacity simply by adding or replacing a drive. With self-healing and drive redundancy technologies, the Drobo helps make sure your data is always safe and accessible.
Since Drobo is 'Data Aware', it tracks where data is on each disk, so it can differentiate between used and unused portions of disk. This expedites rebuild times and reduces your risk of losing data to an additional disk failure.
Virtualization is what enables BeyondRAID to effortlessly change the data arrangement on the drives, for example, changing data stored as a mirror into data stored as parity stripe, without interrupting the user access to data. Virtualization completely decouples the physical space available in the array from the space reported to the operating system. This is how BeyondRAID is able to eliminate the need to manually expand/contract the file system as more space becomes available or is removed.

Things that are great about it.1) Very quiet when under 87% full.2) Very easy to set up, interface, and swap drives.3) Attractive (I actually think it looks cooler with the front cover removed), and the lights on the front are cool too.4) Peace of mind is wonderful. My data is secure, hallelujah!5) Firewire connection is super fast and stellar cool (under 87% full of course).6) This thing came in the box with a firewire cable... that was a very pleasant surprise. Most companies cheap out and make you buy a $40 cable separately to hook up your toys.7) It sleeps and wakes seamlessly with the OS X operating system... sweet!Things that definitely need attention from the developer.1) There is no power switch. When you manually put Drobo in standby mode you must unplug it and plug it in again to get it to interface with the computer. Either add a power switch, best option, or put a radio button on the drobo advance interface that allows reconnection to a Drobo in standby mode... what product doesn't have a power switch anyway?2) When the unit gets to around 87% full it is not easy to add additional data and does not function as expected. First, it deliberately slows down data transfer to a near standstill to encourage adding another drive (or replacing one with a larger drive). I was told by technical support that this was programmed into the unit. A firmware upgrade is supposed to "help" this, but it didn't seem to make much difference for me. Slowdown, by the way, meant it took me almost 5 minutes to load 800 mb onto my Drobo when it told me I still had approximately 190 gb available for "data storage". Second, Drobo sounds like a constant train wreck as it is transferring data around feverishly between hard drives. I began to get worried it would burn up my hard drives. Below approximately 87%, the Drobo is nice and quiet and runs smoothly.Keep in mind that this 87% is really 87% of 50% as the unit only gives you half of the size of the hard drives inserted due to the redundancy of the data backup.3) Warranty needs to be addressed. Nowadays, it seems like electronic equipment has a very short shelf life. It may be built to last a while, but why not offer a 5 year warranty, even if it has to be purchased separately? This way one can feel confident that not only is their data safe, but that the device they entrust to keep their data safe is worry free for a long time. 4) Power cord has a huge brick of a transformer attached. How about building it into the unit itself? No one likes those things.5) I know that these things can take up to four, 4 tb hard drives... but how about a model that can hold say eight hard drives? It is going to be years before we get to the 4 tb mark on individual hard drives.Overall this is a good second generation product and if you can avoid filling it beyond approximately 87%, you will be super happy with it. The good people at Data Robotics really need to address these limitations so that their Drobo can be everything it was promised to be. I have faith! This thing is really awesome if you can live with the limitations, and the good aspects of this product really do outweigh the bad. If I had known all this going in, I would have still purchased my Drobo.

The concept and the device really deserves 5 stars. Its great, setup is easy, and the fact that you dont have to manage the data is a huge weight off your shoulders. Its flexibility is also a huge plus. Im using it primarily right now as a time Machine backup drive for my Mac Pro. I installed 3 WD Caviar Black drives currently. The reason I didnt give it 5 stars is because the first unit I got formatted fine, setup easy and although the initial backup with Time machine took a few tries due to stalling and errors (Which may be due to the TM not the Drobo) it finally took and was running fine for 4 days. Suddenly I had a failed TM incremental backup, I shut down, rebooted the Drobo and the entire drive suddenly became "Read Only" instead of "Read/Write" I couldnt do anything with the current data on it, Disk utility could not unmount it, or repair, etc. Wound up having to do a hard reset of the entire Drobo and start all over. Again, this could have been due to the OS, but it occurred right after I did a firmware update for the Drobo and its dashboard software. None the less, I reset, reformatted, checked permissions, partition scheme and all that, and tried again, still failed initial backups. My only gripe is that I called Drobo tech support for help. They are very helpful and polite, but after trying all of the typical diagnostic procedures over the phone, the issue seemed to have extended beyond the scope of the general tach support they had. I was assigned a case number and was passed to tier 3 tech support which was indicated was the engineers and the "Big guns" Well its been almost 7 days as of this writing and I have not heard any response from them. I will give them the benefit of the doubt and say perhaps they are backed up or busy, but I am just a little let down because in the meantime, I am without my backup and have a expensive piece of equipment that is not operating properly. I opted to, at my own discretion contact B&H and exchange the unit for a new one, which they did without question and promptly, but it would have had been nice to have the manufacturer take the initiative and offer to shoot a new unit out for me and send them they questionable one back so that while tier 3 tech support finishes doing whatever they may be doing, at least a new customer of theirs would not be without the product they paid for. Thats it, my only real gripe. The new unit is working fine, set it all back up, no hitches. The fan is a bit noisy in this unit over the original one I received. But so far so good. I have only had the new unit up for 2 days so far.
As far as the unit itself, its nicely designed, it looks like a glossy black loaf of bread with blue lights. Its really easy to setup and use, if you can put a tape in a VCR (haha) or better yet, if you can put an 8 track tape into a player, you can put a drive in, then it takes over and does its thing. I notice the hard drives run a lot, and the fans kick on often, it seems like its doing "stuff" often, which is a good thing I presume, but it does make some noise, and if the sound of a number of hard drives wacking away in the muffled thumping sound bothers you, then dont expect to have this sitting right next to you on your desk. The indicator lights are really so simple and easy to understand.
I was very tempted to get one when the 1st gen came out, but the USB only interface held me back, no this new 2nd gen has firewire 800 support as well as the USB so it speed up the data transfer for large amounts over the firewire 800.
In closing, I would recommend this to someone looking for a redundant and flexible backup. Im not very well versed with all of the flavors of RAID. I just simply need a solid and easy to use backup in case I had a catastrophic failure with my data. I feel better knowing that the Drobo will hold my entire computers 3 internal drives data out on the drives I have in it now, as well as easily allow me to slide in larger or more drives if need be, as well as protect against any of those drives in itself from failing. SO short of fire, flood, or vandals- and for those theres always fire extinguishers, boats, and guns...(Or heaven for bid another wacky read only fiasco) the data should be safe.
In comparison to other similar devices configured with similar storage capacity, the Drobo takes the pie

Comments about Drobo 4-Bay Hard Drive Array Enclosure:
I bought this product mainly to use as a backup and storage solution for a growing photo library. I have nothing but praise for it so far though i have only been using it for 2 months. User interface is good, easy to use and simple to set up. I was up and running in under 20min. I have not had issue with speed others have mentioned but don't do video editing however some of my larger pano shots are over 1gb. Its so much better than the many ext drives i had clogging up my desktop i only wish i had have bought one much earlier.

Comments about Drobo 4-Bay Hard Drive Array Enclosure:
I now own this device for 3 weeks. Before my purchase I read a good amount of reviews on this site and other sites that offer this product. Some really bad others superior.
After I made up my mind I thought that should give it a try, since I recently moved from a PC-Windows machine to an iMac. With tons of video and photos I needed a solution that would make sense (since it is always growing).
I put in my 4 x 1 TB Hard Drives from my W7 PC, formatted it, moved over all my digital media, and voila...I love it.
I also use it to capture digital video from my camera via FW800, into FCP X...no problem there

Comments about Drobo 4-Bay Hard Drive Array Enclosure:
I purchased the Drobo 4-bay in Aug, 2010 and will begin phasing it out this year. I currently have it loaded with 3-1TB 7200rpm drives and 1-2TB 7200rpm drive. While this system is great for archiving, redundancy and even photo and still graphics work, it is too slow for multi-media or video work. Via FW800 using the AJA System Test App, I only was able to get write speeds averaging 19.4MB/s and read speeds of 24.2MB/s on a 4GB 1920x1080 10-bit video file. For comparison, the other two FW800 drives I have clock at roughly 67MB/s write and 80MB/s read - over 3x faster! So do not purchase this drive for video or high-datarate work.
That being said, for other applications, I think it is a great array. The Drobo dashboard is clean looking, intuitive, and easy to navigate and use. Another big plus is customer service. I had a drive in the array crash and upon calling customer service, the phone was answered in under a minute by someone in the USA. Further, she was friendly, knowledgeable and was able to help me troubleshoot the system without escalating the call. And after replacing the faulty drive, the Drobo flawlessly rebuilt and no data was lost.
So in summary, for video and high-datarate uses, don't buy this Drobo. But for everything else where fast read/write isn't an issue, it's a great option at a reasonable price.

Comments about Drobo 4-Bay Hard Drive Array Enclosure:
I'd heard a lot about this product and decided to try it. I don't have a huge amount of data (compared to others) to store but most of it is irreplaceable. After having two back up drives die, I decided redundancy sounded really good. It was easy to put together and install the two drives I got with it. I was a little confused on the formatting/partitioning piece but the Drobo tech folks were right there to help. I wouldn't say it is noisy but it isn't exactly quiet either. You know when it is running but it isn't annoying. I didn't check reliable because I just got it a week ago and that will take time to tell.

This unit is being used with a MAC/ USB. It is effortless to set up and use. In fact, when purchased, one of the hard drives failed in the first few days and the status light turned red next to that drive and I pulled it and exchanged it and when I inserted the new one the drive automatically began to restore data to it. No control programs - no user involvement. WONDERFUL!!

I have this product for 10 days, and, this far, I can only say that it's great and meets my expectations.
Its very silent, sleek in design, and really easy to operate. The drobo software gave me no problems at all.
Im using it attached to a mac mini i5, 4,0 gigs ram memory, thru a firewire 800 cable.
It stores only media content (tv and music shows, cartoons and movies) making my mac mini act as a media server to the rest of the house computers.
Its fast and reliable enough to this purpose.

Comments about Drobo 4-Bay Hard Drive Array Enclosure:
I use the drobo as a Timemachine backup for my Macbook pro as well as storage for movies and photographs (Raw's and JPEGs). Drobo website provided an easy set up link for time machine set up.
I went with the drobo to avoid the complications of RAID and because the drobo claims to be pretty low maintenance, easily expandable and overall a pretty simple system. Most of this is true. I had a hard time getting it set up but it did eventually work out once everything was formatted and updated. Needed to update the firmware for a few things but in the end it worked.
I use 4 Seagate 1.5 TB drives which are slow (5900 rpm), but cheap since I got them on sale. This system gives me 4.7 TB of space which is enough for now. If I need to, I can upgrade to 2TB or 3TB drives in the future. I went with 4 drives instead of 2 because in the end I got more storage space. Play around with the drobo capacity calculator on their website to find out the best capacity arrangements.
Biggest downside: speed. It took 8 hours for time machine to back up 350GB of data. I haven't transferred my 800 movies yet or my TB of photos. Dreading that experience but I didn't buy the drobo (or slow HD's) for speed, I just need a reliable back up system to preserve data.

Set up is easy and works great, make sure you have full size 3.5inch hard drives tho. Drobo does it all, storage file back up at the same time. With how hard drives like to crash around me and possibly you its a must have for any photographer.

Comments about Drobo 4-Bay Hard Drive Array Enclosure:
I have only had the enclosure a few days, but so far so good. The setup was very easy. Installed the software and plugged in a few drives. Very quick and painless. If only the price of drives would come back down. The setup looks a little more tricky to setup two volumes. I want to do this but have not yet. Also, using the drive with OSX Lion Time Machine has a very unusual work around which they say they are working on a better solution. So, we wait. But, everything else works great.

Comments about Drobo 4-Bay Hard Drive Array Enclosure:
This is my 3rd Drobo. I mainly use them for system and work backups as well as to store videos for my media center (using FW800). This particular one is for backing up my wife's photography drives.
What I like most about the Drobo is the Dashboard and setup. It's simple to setup and get running. Super easy to deal with a hard drive failure while still being able to access all your data.
Since you can mix and max HDD it's great for 'recycling' HDD from one Drobo to the next, when I buy bigger hard drives.
Only CON is this model isn't so fast. So I wouldn't recommend it as a primary drive to work off of but it's perfect for backing up and archiving your work. If you want faster I'd recommend one of the higher end models.
I'd highly recommend them

I needed a solution to store my photos, both raw and edited. They are starting to pile up. Decided on giving this unit a try. Loaded it with 4 Seagate Barracuda 2TB 7200 drives. This unit was up and running in 10 minutes (It would have been sooner, but I upgraded the firmware and Dashboard software as well). It is connected via FireWire to my iMac. It really is a great solution!

At [$] shipped this was a great deal. I fired it up and installed the software on my Mac running Snow Leopard and popped in (4) 1.5 TB drives and have been tossing files at it for a week now and getting all my images and video and other data transferred. So far so good.I put in 5400 rpm drives and I can barely hear the fan when it's running and can't hear the drives at all. After 15 minutes of inactivity it auto spins down the drives and sleeps them.I have been watching Drobo for almost 5? years and the time was right for me...glad I did it!

I'm using my Drobo 4-bay gen-2 for onsite storage and computer backup. I have 4 Western Digital Caviar Green 2 TD WD20EARS hard drives in it, giving me 5.44 TB of space. It run very quickly, very quiet and was easy to set up using the Drobo Dashboard version 2.0.3 software. It's not cheap but when you lose 1 TB of photos on a [$] external hard drive you start thinking the cheapest way may not be the best way.
