Hardware preview: DroboPro

➡ Updated 1/14/19: I have revised my opinion of Drobo devices. After experiencing multiple, serious data loss events on multiple Drobo models, even recent ones, I no longer consider them safe for my data.

➡ Updated 11/23/09: The new DroboElite is now available. It differs from the DroboPro because it offers two Gigabit Ethernet ports instead of one, multi-host support, and up to 255 Smart Volumes.

Today, April 7, 2009, Data Robotics launches a new product aimed at professionals and SMBs: the DroboPro. I got a preview of it yesterday. Let me share what I learned with you.

The DroboPro has some really cool features, some of which I, along with others, anticipated and looked forward to seeing. As I wrote in my review of the Firewire Drobo, Data Robotics was looking at making an 8-drive Drobo, possibly rack-mounted. I also thought they might introduce the capability to safeguard against two drive failures. And, as I wrote in this comment on that same review, in response to a reader’s wishlist for the Drobo, I thought they might at some point build networking capabilities right inside the Drobo.

Well, the new DroboPro does all those things and more!

8 (eight) drives
2 form factors: desktop and rackmount
Dual drive redundancy
Gigabit ethernet
iSCSI
Smart volumes: create up to 16 different virtual volumes, each of which can grow to 16TB
Price is $1,299 for entry level DroboPro or $3,999 for a loaded model with eight 2TB drives
Instant $200 rebate with customer loyalty program

Let’s dive into those new features a bit. Keep in mind my knowledge is as yet limited, since I haven’t seen the full specs; I only had a phone briefing.

8 drives

You know how the drives are arranged horizontally in the regular Drobo? They’re arranged vertically in the new DroboPro, which is about the same height, and a little less than twice the width of the original.

Two form factors

The DroboPro comes in a desktop form factor which is 12.17″ wide, 5.46″ high and 14.1″ long. The length is about 3″ more than that of the original Drobo. I think the extra space houses the additional circuitry for the network, power supply and other features.

The other form factor is a rackmount with a 3U height. If I understood correctly, the rackmount kit can be attached and detached as needed, so you can interconvert between the two form factors if you like.

Built-in power supply

One thing that’s easy to miss if you look at the back of the DroboPro is that it no longer has a DC adaptor port, but a regular 120-240V connector. Have a look and see. This means the power brick which converts 120-240V AC to 12V DC has been eliminated. You’ll also notice a power switch on the back. That’s new too.

Dual drive redundancy

As it was explained to me, the DroboPro comes standard with single drive redundancy, and the dual drive redundancy is an option that can be turned on at any time. In case you’re not familiar with the concept, this means two of the drives inside the Drobo can fail, and your data will still be safe.

Gigabit ethernet

Business-class networking is now built right into the DroboPro, along with enterprise-class features, like iSCSI with automatic configuration. The ethernet port on the DroboPro does not replicate the functionality of the DroboShare, as I initially thought. It only works through the iSCSI protocol, which means it needs to be mapped directly to a host, like a server or workstation, which can then share it among multiple servers or workstations. In that sense the DroboPro is not a NAS (Network Attached Storage), but a SAN (Storage Area Network).

iSCSI

If you’ve set up iSCSI volumes in the past, then you know how much of a headache they can be, and how bad the performance can be if it’s not set up correctly or if the hardware isn’t working as it should. I know firsthand about this. With the new DroboPro, the iSCSI setup is automatic. It’s as easy as plugging it into the network. The Drobo Dashboard software then finds it and mounts it as a volume on your machine via iSCSI. The work is done behind the scenes so you don’t have to worry.

For Windows, the DroboPro uses the Microsoft iSCSI initiator, and for the Mac, the folks at Data Robotics wrote their own iSCSI initiator. Those of you who work with Xserve and Xsan use Fibre Channel technology to connect to the network volumes, and you may wonder why Data Robotics went with iSCSI. It’s because iSCSI is more utilitarian. It doesn’t require special network hardware to work; it can use the existing ethernet network infrastructure, so there’s a lower cost of entry and maintenance.

I was assured that iSCSI throughput on the DroboPro is very fast. I guess it’s up to us to do some testing once the DroboPro starts to ship, so we can see just how fast it is. See the iSCSI guide on Drobo’s website for more details.

Smart Volumes

With the DroboPro, you can create up to 16 different virtual volumes, each of which can grow to 16TB. This is very important for the enterprise market, where companies want to be able to separate the data onto separate volumes and assign separate access privileges to each. Those of you who are network admins can readily appreciate how useful this is. Those of you who are creatives can also appreciate being able to assign a volume for Time Machine backups, one for videos, one for photos, and so on. Furthermore, each volume can be resized as needed, which is a huge leap forward compared to the difficulty of resizing LUNs set up over RAID volumes.

Price

The entry level DroboPro (enclosure-only) costs $1,299. The high end DroboPro, which includes the rackmount kit, two drive redundancy and is pre-loaded with eight 2TB hard drives for a total of 16TB of space, costs $3,999. There’s also a handy customer loyalty program which will give you an instant $200 rebate if you’ve purchased a Drobo in the past.

Those of you who might balk at the price should compare the features and ease of use of the DroboPro with other comparable products on the market. I’m going to walk you through a different kind of comparison, one that looks at the cost of the original Drobo and the cost of the new DroboPro.

Think of the DroboPro as two regular Drobos in one. The original Drobo is $499 for the enclosure, so that brings the price to $998. The difference between $998 and $1,299 is made up by the additional networking features and the complexity of the circuitry and auto-management algorithms of an 8-drive array. Keep in mind the DroboPro has enterprise-class features like dual drive redundancy, iSCSI and smart virtual volumes. Those features alone warrant charging several hundred dollars to thousands more for it, as other companies who make similar products have already been doing.

Summary

The DroboPro is a fantastic addition to the Drobo line. Its enterprise-class features, its incredible ease of use, and its unmatched storage flexibility make it the perfect external storage solution for busy professionals with serious storage needs or business server rooms. Users will appreciate all of the space it makes available for their work, and system admins will appreciate how easy it is to set up and maintain. From a design point of view, it’s a drool-worthy beauty. Having been a Drobo user for almost 1½ years, I can tell you it is my storage solution of choice, and I look forward to upgrading to a DroboPro some day.

Hardware review: Second-Generation Drobo

➡ Updated 11/23/09: The new Drobo S is now available. It has five drive slots, single or dual-drive redundancy, and triple interfaces (eSATA, FW800 and USB 2.0).

My review of the new Firewire Drobo is somewhat overdue, but I wanted to spend a few good months with it before I wrote it. I have now spent that time, and am happy to say this new Drobo can be an avid computer user’s single storage device. Whatever reservations I had about the first-generation Drobo were eliminated by this new version, and I can now wholeheartedly recommend it to anyone who needs to store a large amount of data and safeguard against a hard drive failure.

Background

You may or may not know that I also reviewed the original Drobo. I published that review in December of 2007, after spending about a month with a USB Drobo, and updated it frequently since then, outlining the various good or bad points I found during my heavy-duty use of the device. Since that time, I became the owner of four Drobos (three USB Drobos and one Firewire Drobo) and found a couple of firmware bugs — I’m not claiming to be the first one to have found them, just saying I also found them — which were later addressed by firmware upgrades. The bugs were an overestimation of used space, and a significant drop in transfer speeds after the Drobo’s used space reached 80% or greater of the total available space. I had a number of different issues with my Drobos, all of which were detailed in my original review, and are now resolved.

I also wrote about the Drobo from the perspective of product design for the consumer and corporate markets. Tom Loverro, one of the execs from Data Robotics, responded at length to my article with some very interesting insights about the inception and introduction of the product to those markets.

What’s new

What is it that differentiates the new Firewire Drobo from its predecessor? I’ll summarize it:

Faster read/write performance thanks to an upgraded core processor and faster transfer method (Firewire vs. USB); slower read/write performance was a big point of contention with the first-generation Drobo
Two Firewire 800 connectors in addition to the USB 2.0 connector, so you can daisy-chain other Firewire devices to the Drobo
Different design for the cooling grille and a bigger cooling fan (the fan, without the cooling grille, was a silent upgrade that was also applied to some late builds of the first-generation Drobo)

Faster read/write performance

The official specs from Data Robotics quote the transfer speeds as follows:

FireWire 800: Up to 52MB/s reads and 34MB/s writes
USB 2.0: Up to 30MB/s reads and 24MB/s writes

I can vouch for the faster read/write performance myself. As a matter of fact, I can safely say that the performance approaches that of my WD My Book Studio Edition II, which is also a Firewire 800 device, that I have used in both RAID 0 and RAID 1 configurations. In layman’s terms, I can copy about 800 MB – 1 GB per minute to my Drobo, while I can copy about 1 GB – 1.2 GB per minute to my WD My Book Studio Edition II drive in RAID 1 config. These are large files I’m copying, ranging in size from 1-4 GB.

If we do some quick math with the official figures, we can see that you could get up 2040 MB or about 2 GB per minute written to the Drobo over a Firewire 800 connection per the specs. In my real world experience, I was able to get about half that, as you can see above. I don’t think that’s a bad thing. Again, you have to compare the Drobo with another Firewire 800 device, and I did. If I can get about the same performance from my Drobo, which has to write the data across four drives, as I can get from my WD Studio Edition II, which only has two drives to worry about, then I’m pretty happy.

Two Firewire 800 connectors and different cooling grille

Have a look at this photo to get a better look at the different back design for the new Drobo. You can see the two Firewire 800 connectors, the USB 2.0 and DC connectors and the different grille design below.

Miscellaneous notes

In the other-things-that-are-different department, I noticed that Drobo now allows people to format its volumes in the EXT3 file system (Linux), in addition to NTFS, FAT32 and HFS+, although they do say that Linux support is in beta on their website. It has nothing to do with the new Drobo 2.0 hardware, as this involved a firmware upgrade and a Drobo Dashboard upgrade, not a parts upgrade, but it’s a pretty cool move on Data Robotics’ part.

Another thing that looks a bit different is the power supply. The original one was a simple plastic brick, but the new one has a line motif going across it, parallel to its long axis. This newer power supply was also shipped with some of the late builds of the previous-generation USB Drobo.

If you look at one of the photos I posted above, the one of the new Drobo’s back, you’ll see a Reset slot. Can you see it, to the left of the FW800 connectors? It was present on the back of the original USB Drobo as well, to the left of its main (and only) USB connector. Sure enough, there’s even a tech note about it, which explains how to wipe the Drobo clean. This means it’s a dangerous little slot, so don’t use it unless you really mean it.

I never got around to posting the Drobo’s dimensions in my original review, so here they are. They haven’t changed with the new Drobo. I like the form factor, I hope it keeps staying the same. In all likelihood, it will stay the same for this four-drive version of the Drobo. I know, thanks to a product survey sent out to selected Drobo customers, that Data Robotics is thinking about or working on an 8-drive and possibly a 16-drive version of the Drobo, one of which (or both) is rack-mountable. Those should be some very interesting products for the enterprise or for those with larger storage needs than what the four-drive Drobo can provide. I understand that Data Robotics is also working on the capability to safeguard against two drive failures in those larger Drobo models, which should be a very cool feature indeed.

In terms of storage flexibility and the safety of one’s data, I believe the Drobo is unmatched. There is no other product like it on the market. The only thing that’s holding it back at the moment, storage-wise, is the capability of the hard drives themselves. Only recently have the problems present in the 1.5TB drives from Seagate been worked out, and only in recent weeks have I seen 1.5TB and 2TB drives from other manufacturers like Samsung and WD. This means, according to the Drobolator, that you can get up to 5.5TB of disk space on a single Drobo unit, which is pretty amazing, but still far from the 16TB limit. I think 16TB is a lot of space to get from a single device, and it should suffice for the needs of most people for the next few years.

Cheers to the new and improved Firewire Drobo!

The Drobo is available for purchase from Amazon or B&H Photo.

You simply can't depend on computers

Take it from someone with 15 years of experience in Information Technology — me. You cannot depend on computers.

Every single time in my life when I’ve had to depend on a computer to help me do something under a tight deadline, some glitch intervened. Something inevitably went wrong. Something didn’t work. I wasn’t able to get things done.

Generally speaking, it’s Windows computers that are more problematic, particularly when it comes to peripherals like printers or drives or USB sticks or webcams or whatever. Apple computers are slightly less unreliable, but I’d still say the same rule applies: you cannot depend on any computer for anything critical.

Need to print something in a hurry? The printer will inevitably not work, or the computer will slow up all of a sudden, or it won’t recognize the printer, or it’ll clam up, or the editing software will start acting up. Need to get to a document on a USB stick? Somehow, the stick will become unreadable. Or maybe it’ll work, but all of the apps on your machine will become so slow that you won’t be able to make the changes in time for the deadline. Need to edit something online? Your Internet connection will go down; if you’re on WiFi, that’ll go down or start cutting out. Or the remote servers will become unavailable even though other websites work just fine. Need to install an app in a hurry? Something will go wrong. Either you won’t have the right version for your OS, or the installer will freeze mid-install, or the site where you need to get the installer will stop working. Have to do a video chat? Guess what, if it’s an emergency, your webcam won’t work, or the chat will cut out mid-speech, or the sound will become garbled. Something will go wrong. It’s a given.

I don’t care if your computer is squeaky clean. I keep my machines that way, and yet I still have problems. There are no viruses, no spyware, no bloatware on my machines, and yet something always goes wrong when there’s a tight deadline involved.

The only way you can circumvent this rule is to have entire server rooms with IT staff standing by at your disposal. Even then, you can be sure that the weakest link in that chain will give, and right at crunch time, something will go wrong.

Take my word for it. I’ve worked in all levels of IT, from help desk up to the director position, and have put together computers and servers and server rooms. It pains me to say this, but after so many years in IT, I have to face the facts. You cannot depend on computers when you’re in an emergency. Don’t count on it. Computers are for entertainment purposes. They’re nice and they wow you when you’re playing around or doing normal stuff. But when it comes time for them to deliver under pressure, somehow they fail. It’s just the way things are. When they fail, and they will fail, deal with it. Try not to get a headache like the one I have right now. Go outside. Take a walk. Breathe deeply. Remember, it will pass.

A look at the Samsung T260HD HDTV widescreen monitor

I tried, unsuccessfully, to use an HDTV as my main computer display in the past. Although the specs of that Sony HDTV were superb, its brightness and contrast levels were made for a TV, not a computer display, and it gave me headaches when I stood close to it, as I would when I’d work at my computer. Things have a way of working out though. One of the commenters on my HDTV post, Adam Juntunen, pointed me to something that might just work for my needs.

Samsung has come up with a product that is made to work as both a display and an HDTV. It’s the first such product that I’ve heard of: the T260HD, a 26″ widescreen computer display and HDTV. The T260HD is part of a line-up of four monitors which includes the T200HD (20″), T220HD (22″) and the T240HD (24″).

What sets the T260HD apart for me is the fact that it was made to fulfill both functions from the factory. Although I haven’t used it (yet), my hope is that the Samsung engineers accounted for the difference in display characteristics that is needed when one uses it as a computer display vs. a TV. What is heartening for me is that it’s listed among the computer displays, not the HDTVs, on the Samsung website, which means it’s really more of a computer display than an HDTV, which is just what I need.

The design makes this display stand out. The enclosure is made of glossy black plastic, and it looks as if there’s a clear panel of glass set over the front of the display, which should make it easy to clean. A hint of maroon color marks the bottom of the enclosure, right below the logo, giving it a distinctive look. I do hope though that the glossy black plastic doesn’t scuff easily. Other Samsung TVs do scuff over time, which means that as you dust them, small hair-width scratches appear on the plastic, marring its glow.

Promotional: Don’t spend too much on flat screen TVs; there are flat panel TV deals you can take advantage of. LCD TV deals are available for consumers to buy at discounted prices.

The specs listed on the Samsung website are thin on the details, and I can’t make out whether its color depth is 8-bit, 10-bit or 12-bit. My guess, given its price, is that it’s 8-bit or 10-bit — probably the former, not the latter. Color depth in a display is a very important specification, because if you work with photos, like I do, and your DSLR captures 12-bit or 14-bit color images, you won’t be able to edit them competently on a display whose color depth capabilities are much lower. A 6-bit display, for example, like many laptops have, would be fairly useless to you, because it just won’t reproduce the color tones faithfully.

Let’s have a look at some of the salient features of this display:

Full HDTV monitor: that’s good, and also to be expected since it’s a computer display as well, and its resolution is 1900 x 1200 pixels.
Dolby Digital Surround sound: it has invisible speakers built in, and they’re rated at 3 W each; I’ve heard these types of speakers on other Samsung products, and they’re pretty good — certainly a lot better than most monitor speakers.
Dual HDMI, DVI and VGA inputs: that’s impressive for a 26″ display. I see that Samsung didn’t skimp and even included a SCART connector for the European countries. I love that.
Low power consumption: one spec says it uses 0.3W in Standby mode, yet another says it uses < 2W in that same mode. At any rate, it only uses 70 W max, and that’s great for a 26″ display.
10,000:1 dynamic contrast ratio: I think this spec is trumped up, as I see it on a lot of other, cheaper displays and TVs. I have no idea what it means. Supposedly, the increased contrast between light and dark helps you see things better. I’ll be the judge of that when I try it in person. I see that the Apple Cinema Displays are listed at a 700:1 contrast ratio, which I think is a much more reasonable figure.
5 ms response time: this is a little sluggish given that most displays in that size are at 3 ms. Still, it’s better than the Apple Cinema Displays, which are still listed at 14 ms. I think 5 ms is sufficient for most movies and video games, but then I’m not into the violent, fast-paced video games.
300 cd/m² brightness: this isn’t as bright as other displays in the same sizes, which are at 400-700 cd/m², but you know what, I’d rather not have headaches caused by too much brightness, so this should be fine for me.

What I’ve seen so far of this monitor has certainly whet my appetite, and I’d love to try it out for myself. If and when I do, I’ll let you know how it works out.

Predictions about computer drives in the future

On 1/16/09, Computer World published an article where the author paints a future full of SSDs. He puts forth the idea that drives will not only be replaced by memory chips, but that these memory chips will be integrated into the motherboard, doing away with the SATA interface. There are a number of things I don’t agree with in that article, and I’m not the only one who’s annoyed. Others have called out the author for his statements as well.

For one thing, let’s remember that computer memory once relied on chips integrated into the central circuits. Going back to that sort of approach would be like going back in time. Weren’t we supposed to progress, not regress? The advantages have to be truly worthwhile, and I’m not convinced.

A claim made in the article is that of increased speed: “By making the drive part of a system’s core architecture — instead of a peripheral device — data I/O performance could initially double, quadruple or more.” I love these nebulous claims, don’t you? It could double, quadruple or more. Hey, why not 8x faster? Maybe 16x faster? Let’s just inflate the numbers, it looks great on paper…

From my experience, I noticed that transfer speeds to flash memory vary tremendously — based on how much used space there is on the memory itself, or the file size. Larger files transfer much faster than smaller ones. Sure, in my experience, there was a SATA or USB interface in the way, but that doesn’t change what happens with the flash memory itself.

We should also keep in mind that flash memory is limited in the number of write operations it can take before it expires. On the other hand, regular hard drives have a much longer life span. I for one don’t want to be in a situation where I have to replace an expensive SSD on my laptop because I’ve saved one too many files and it has just gone belly up.

That brings to mind another issue: will these SSDs be soldered onto the motherboard, or can I pull them out and replace them as needed, like I do with RAM modules? I think you can readily imagine how inconvenient it would be to have to service your computer if its SSD is soldered onto the motherboard.

How about space on the SSD? What do I do if I want to increase the space on my drive? Do I have to buy another full SSD? I’d much prefer we had SSD bays, like RAM bays, where I could stick additional SSD modules to automatically increase the space, just like it works with RAM. A partitioning tool integrated within the OS should then allow me to resize my existing partitions and spread them over the newly available space, or to create another partition out of that space.

I keep hearing people say that 250GB or 160GB is plenty of space for your laptop. That’s nonsense. I’m always maxing out my laptop’s hard drive when I go on trips, because I fill it with photographs and videos which I then unload to my external storage when I get home.

I find that for my needs, a 500GB or 1TB laptop hard drive is what I need right now. At some point in the future, I may need more. I haven’t started working with HD video for example. I know that’s a tremendous space hog. I think a 1TB drive would be the minimum I would need if I started to work in that arena.

With SSDs, price is still an issue, and so is space, at least for now. I just don’t find it practical to spend money on SSDs at the moment, and I don’t think my opinion will change unless their prices and storage specs start to match those of regular hard drives.While we’re on the subject of price, where in the world did Gartner get their figure of 38 cents per gigabyte? That’s the figure quoted in the article. I’m sorry, Gartner, but you folks need to check your math. I came up with 9 cents per gigabyte recently.

On the other hand, I do understand that the additional interface between the motherboard and the hard drive is a bottleneck. If we can do something to speed that up, I’m all for it. But you’ve got to prove to me (and to other consumers out there) that your technology is affordable and reliable and offers tangible benefits other than tech media hype.

I’m also excited about the possibility of increasing drive space on a modular basis, where I simply put in more SSD modules in expansion bays on the motherboard, like I do with RAM. But there’s no indication that we’re heading in that direction from the article itself. Until we get to that point, I’ll still continue to think that SSDs are aimed at the wrong market segment. Not everyone is a MacBook Air-toting management type. The bulk of computer users out there need affordable technology with plenty of storage, well made, and reliable over 3-4 years or more. SSDs just aren’t there yet.
