I’m a sucker for storage and networking (duh) so combining these two great tastes really gets me interested. I’ve been watching the CloudEngines Pogoplug with interest. It allows you to share a USB external hard disk drive across a LAN and even allows access over the Internet using the Pogoplug service. My friend Howard has one and says it’s cool (though slow).

Last year, Seagate licensed the PogoPlug technology from CloudEngines and came out with their own-brand FreeAgent DockStar Network Adapter which includes the service. In addition to the special connector for Seagate’s pre-GoFlex portable hard drives, the DockStar has three standard USB ports for any old USB drive you might have hanging around.

I guess these things haven’t been selling all that well (especially now that GoFlex is here), so Seagate slashed the price from $99 to $39. You don’t need a Seagate drive at all to use it. The PogoPlug Internet service is iPhone-compatible, too!

The $23 deal from 1 Sale a Day expired, but the Seagate offer is still a great way to buy a PogoPlug cheap!

Seagate's new GoFlex external drive lineup moves the smarts into the cable, simplifying function and connectivity upgrades

The external hard disk drive market is incredibly hot right now, but it’s also ultra-competitive. Stalwarts Seagate and Western Digital battle it out with everyone from disk makers like Toshiba and Hitachi to PC hardware companies like HP, Iomega, LaCie. The latest trend is dockable multi-function drives that are friendlier to use and offer advanced features like video playback. Most docks rely on USB 2.0, but Seagate just dropped a bomb on the industry with a simple twist: They moved the intelligence outside the case, repackaging the standard internal SATA connector as GoFlex, an external link to a variety of docks and adapters.

The Trouble With Hot Products

External drive makers face a dilemma: Fierce competition has driven down the price of external USB hard disk drives, hurting profit margins. Most brick-and-mortar stores sell basic external USB drives even cheaper than the bare hard disk mechanism contained inside, and sales can push them lower than online bulk drive purchases. It’s nice to be in a hot market, but not so great when it squeezes out all of the profit.

Drive makers responded by adding features. A few years back, the trend was upscale “pro” models with 400 or 800 megabit FireWire interfaces, one-touch backup software, or built-in encryption. We also saw “fashion” drives with sleek lines and bright colors. But these were one-sale sweeteners and did nothing for the brand as a whole. The next step was the introduction of desktop docking stations, encouraging the purchase of more devices from the same vendor. Then came a wave of video playback stations that connect to a television.

But all of these devices were limited by the USB 2.0 interface they used. USB was good enough for many uses, but it was too slow for some users. Those wanting faster performance simply ignored the dockable lines and went straight for FireWire 800, eSATA, or iSCSI over Gigabit Ethernet. The release of USB 3.0 forces vendors to scrap their current docks anyway.

What’s the Big Idea?

Seagate took these marketing lemons and turned them into lemonade. Their idea is simple: Move the interface and feature smarts outside the drive case and into the cable or dock. The GoFlex interface is almost identical to the standard SATA data and power interface found on physical hard disk drives. This gives plenty of performance, future-proofs the line as drive speeds increase, and allows a wider variety of interfaces to be used.

Take a good look: GoFlex uses SATA data and power connections!

Let’s say you go out and buy a simple basic 500 GB FreeAgent GoFlex portable drive. It comes with the USB 2.0 cable but not much else. You can still get a TV dock like before, but now you can also order up some speed with a FireWire 800 or eSATA Upgrade Cable. And you can mix and match drives and cables, using eSATA with your desktop and USB with your notebook.

This is a win from Seagate’s perspective, too. Assuming they made the connector just different enough to not be compatible with other vendors’ SATA drives, they retain the brand lock-in advantage while offering enticing features to their customers. Assuming they eventually offer GoFlex drives without the cable as upgrades for existing users, the technology also allows them to underprice their competitors.

My Take

GoFlex is definitely a clever marketing idea, repackaging existing technology in a novel way. I am pleased to see an upgrade path to faster interfaces like USB 3.0 and eSATA, though I wish Apple would hurry up and offer these ports on their machines. And I am eager to try the technology out, especially with third-party drives.

I imagine that GoFlex will give Seagate quite a differentiator in a competitive market and will encourage brand loyalty among customers. But TV docks have not been a big success (judging from the clearance section at my local Best Buy) and I doubt this will change that situation. I expect this technology to be a hit, but drives will be drives.

What Is Drobo?

First, let’s talk about what Drobo’s current product is and isn’t. It is basically an external USB drive enclosure for a single PC – think about your basic Western Digital MyBook or Seagate FreeAgent and you’re almost there. But it doesn’t come with any hard disks; instead, it has slots for four that you add yourself, so adjust your thinking accordingly.

OK, you say, I’ve got that. A shiny 4-slot RAID enclosure, right? Well not so fast. It doesn’t use any of the common RAID levels, and proudly so. Instead, it uses virtualization and what looks to be automated block-based data mirroring to protect the data. It appears to protect data “on write”, meaning it is ready to run quicker when you add or replace a disk. Instead of running through a time-consuming RAID rebuild, it would just copy the blocks needing protection to the new disk.

Yeah, I said virtualization, but that’s not the only enterprise storage buzzword you’ll find in this little device! It’s also got thin provisioning! No kidding – in order to deal with the fact that operating systems don’t like to see their disks grow, the Drobo just tells the OS that it always has 2 TB available, regardless of the number or size of the disks installed. This might prove disconcerting to users, though…

Data Protection

This alternative approach to data protection can lead to some strange capacity situations. Basically, the device reserves an amount of space equal to the largest drive for data protection. Note: the following examples use the weird disk industry capacity numbers, not the actual usable numbers…

Put in three 500 GB drives and you’ve got 1 TB to use (500+500+500-500). Add another and you’ve got 1.5 TB (500+500+500+500-500).

Swap one of those half-terabyte drives out for a 1 TB unit and the Drobo “reserves” half of the big drive and treats it like a 500 gigger, so you still have 1.5 TB available (500+500+500+1000-1000). This can lead to some weird situations when really large drives are mixed with small ones – A 100 GB drive and a 1 TB drive equals 100 GB of space (100+1000-1000), potentially confusing customers who just spent some big bucks on a giant disk!

This guy would be better served capacity-wise by popping out that little 100 GB disk and just using the terabyte unit, which would give 500 GB of usable space. That’s right, the unit also allows you to use a single drive, and configures it to “protect” itself! Of course, the engineer in me wonders about the logic in mirroring blocks to the same drive – protection from drive failure, of course, would be lacking, but also think of the seeking as the drive churns to write every I/O twice!

Try out the online “Drobolator” to see how it works for yourself…

Drobo Grows Up

But I digress. Just put two or more drives of similar sizes in your Drobo and be done with it. One really nice thing about the device is that you can mix and match drives as needed, swapping out big and small depending on what you have available. Mixing drive types and sizes would disagree with most RAID controllers, but the Drobo eats them up, allocating as effectively as possible.

This is probably the nicest aspect of the device. You just leave it on and connected and in use and add and remove drives according to your needs and resources. Drobo handles all the setup and configuration – just slide the drive in and you’re done. Once you’ve initially formatted the 2 TB (thin provisioned) drive, you never have to do any more configuration. Data migration is unneeded too, since Drobo’s data protection system keeps the information continually available. Start with the old 160 GB drives you have today and swap them out for 500 GB or 1 TB drives next year and everything just works.

One of the best sources for big cheap drives is likely to be those selfsame MyBook and FreeAgent external disks I mentioned above. These often go on sale at big-box retailers for well below the cost of a bare drive, and most use the best SATA drives offered by their manufacturers. The MyBook Premium ES I have, for example, included Western Digital’s impressive 500 GB Caviar SE16 drive mechanism. Purchased at Best Buy for $139, it was far cheaper than the drive alone would have been at the time. While the old Maxtor Personal Storage 3200 used a PATA drive (I checked…), the newer ones apparently switched to SATA, too, and were on sale for $79 for 500 GB last week!

I’ll Buy One When…

Despite my interest in the device, I don’t have a Drobo myself, and probably wouldn’t buy one at this point since it doesn’t really meet my needs. First, Drobo is a USB-only device for PCs and Macs. Although I bet the Linux EXT3 filesystem used by my Linksys NSLU2 home server would work, it’s not explicitly supported by the company. If it was a NAS device, serving storage over Ethernet, I would be much more interested in adding it next to the Slug.

But I’m not a typical end user – most people use a home desktop as a standalone device and would be pleased with an easy to use USB device with massive storage. One issue for these folks is that many use a laptop as their only system, moving around the house, and the chunky Drobo wouldn’t be a good solution for them.

But if you’re a Mac desktop user, Drobo looks like an awesome choice. Add Leopard’s innovative Time Machine to a Drobo and never lose data again!

One device that I would love to hook a Drobo to is my TiVo Series 3. It would be brilliant to have a super-reliable, upgradable storage system to hold video content with no management needed. But the device lets me down here again since the TiVo needs eSATA not USB storage.

Maybe Drobo 2 will add eSATA? NAS? Coffee making?

Oh, and if you were wondering what Geoff Barrall of BlueArc did for his next act, look no further than Data Robotics! Quite a change – enterprise NAS to consumer storage… Who’s your marketing genius, Geoff?
