Where Is Thunderbolt?

Posted by on December 11, 2011

[Updated 12/13 with clarification on Promise and more info on the incremental cost.]

I needed to buy more storage for my editing system – as if needing more storage for video editing is a surprise or something…

Anyway, I decided that since one of my editing systems supports Thunderbolt, I would buy a Thunderbolt RAID. Except the only ones currently available seemed to be from Promise Technology. Promise has been making and selling RAIDS to the video editing market for more than a decade. As Andrew pointed out in the comments: “Promise succeeded Apple’s Xserve RAID with their vTrak RAID.” As you can see from the comments below, lots of people like them a lot.

However, I decided to see what else was on the market.

And, hmmm, there’s not a whole lot else on the market. So, I decided to do some research and had a number of off-the-record conversations with different hard drive vendors to figure out why – when we are almost a year after the launch – there are so few Thunderbolt units available. Here’s what I learned.


Basically, Thunderbolt was released to the market too early. Thunderbolt requires not just one chip from Intel, but a master chip and a variety of supporting chips to be able to handle all the signal processing.

The first problem was that there was a shortage of both the master chip and the supporting chips.

Next, all these chips needed to be integrated onto a new IC board. Anytime hardware engineering is involved – as opposed to making software changes – a minimum of six months of engineering and manufacturing time is involved.


In fact, this hardware board with all these chips takes so much space that it won’t fit inside a standard enclosure – in general, it requires about another 1/2 in height inside the RAID unit.

This is space that, in smaller units, just doesn’t exist. This means that many manufacturers need to retool their enclosures to support the new protocol hardware.


Once the hardware has been figured out, the SDK (software development kit) necessary to support Thunderbolt was several months late coming to market – most drive vendors didn’t get them until early summer. In fact, the specs were published several times – and kept changing with each iteration. This is good, in that it allowed the protocol to improve, but every change caused delays in creating software needed to support the protocol.

In addition, Thunderbolt requires significant support from Apple and Intel engineering to explain how the new system works so that RAID manufacturers can get their systems to interconnect properly with this new protocol.

And, because Apple and Intel do not have unlimited engineering support staff, not all RAID vendors were able to access the engineering help they needed in a timely fashion. So, some vendors are farther along in their development than others are.

There’s also, apparently, a political issue. I was told that some vendors were given market exclusivity for a year after the announcement – an exclusive period that expires just before NAB next year in April.


There are many elements of potential good news here. First, every drive manufacturer that I spoke with is extremely interested in developing for Thunderbolt – so, while the devices may still take a while longer to get here, when they do arrive, they will arrive in quantity.

Second, Intel has already announced – at least to the drive vendors – a second generation bridge chip that includes both the Thunderbolt master chip and all the supporting chips on a single chip. This will vastly reduce both the amount of engineering that is necessary to support the new protocol and the amount of space it requires. From what I have been told, this new chip will support both FireWire and Thunderbolt on the same chip.

However, we probably won’t see these second-generation chips in quantity until late in the first quarter next year.

Intel is also working on a third-generation chip which supports data transfer over fiber-optic cable, but that chip probably won’t show up until 2013.


As one of my contacts told me, all new technologies are more expensive than current technologies. This was true with USB, FireWire, even Blu-ray players; and is true with Thunderbolt. Costs don’t fall until enough people adopt the technology to allow increasing volume to drive down costs.

“The cost of Thunderbolt will remain higher than alternatives until native implementations are made into motherboards and the external devices and if and when this happens we could see the price drop very quickly.”

In this conversation, his feeling was not that the technology was announced too soon, but that the implementation of this new technology takes a while to figure out.


So, what’s the take-away? Thunderbolt is coming – but the majority of units probably won’t arrive in quantity until the second quarter next year. By a year from now, we should have a wide variety of Thunderbolt devices to choose from.

Initially, most Thunderbolt devices will probably support RAID level 0 or 1 – which provide speed or redundancy, but not both. RAID level 5 units – which are both faster and more secure – will take longer to get to the market in quantity.

For now, though, we need to wait.

Let me know what you think.

    I bit the bullet and bought a Pegasus R4 — it is blazingly fast and supports RAID level 5, so I’m feeling comfortable that the data on it is safe. It is expensive, for sure, and it’ll be great once there’s competition to bring down the costs, but so far, I’m really happy with the Pegasus.

    I have been using the Lacie Little Big Disc Thunderbolt 1TB for about 6 weeks. I can edit FCPX on my iMac with a second screen and then go to a client with my MacBook Pro (also works with second screen) and make fine cuts. All has worked well thanks to your FCPX training. I would like the expensive SSD version but at the moment it is available on the Apple US site but not UK. When I work on location I would feel more secure even if it is at a price. Best wishes Barney

    I had talked to two manufacturers a couple of months ago and they said they wouldn’t consider bringing a drive to market until the new Intel bridge chip is available. Without that chip, Thunderbolt is the same speed right now as eSata so it’s not worth it yet….

  4. Caesar Darias Dec 12, 2011 14:55

    So are you saying that the Pegasus product does not do what Pegasus and Apple claim it does?

  5. Paul Cormier Dec 12, 2011 15:47

    i have the pegasus connected to an iMac as well as another iMac Networked to the first iMac… both working with Lightroom and aperture and even Final Cut X…

    it has worked Really well

    No complaints as of yet…

  6. Larry Dec 12, 2011 16:15

    No. No. No. No.

    Absolutely not. I say *nothing* bad about Pegasus. Simply that I was struck by the lack of other Thunderbolt systems in the market and wanted to find out why.

    Promise has been building Raids since way over a decade now. I would trust Promise more than pretty much any other hard drive vendor to build a decent product that meets quality requirements.

    Thanks for this comment. It is always good to hear from folks that are happy with their hardware. And I’m happy to share the news.

    From AppleInsider, Friday, April, 15, 2011

    “Intel announced this week that it will ship silicon that will support both USB 3.0 and Thunderbolt in 2012. According to CNet, Kirk Skaugen, vice president at Intel’s Architecture Group, said he believes the two technologies are “complementary. Support for both Thunderbolt and USB 3.0 will appear in Intel’s next-generation chips, code-named “Ivy Bridge.” Ivy Bridge is the successor to the “Sandy Bridge” processors that began shipping earlier this year.

    How does this fit into the mix?

  10. Larry Dec 13, 2011 01:35

    Ivy Bridge is the second generation chip I mentioned in my blog – it is the key element, along with reasonable supply – that is necessary for most hard drive manufacturers to have the necessary hardware chips to easily support Thunderbolt. Intel has always been a big booster of USB, so their support of USB 3 is not a surprise.

    The key is “how soon” Intel will ship these new chips and what the manufacturing constraints are.

    We have two Pegasus R6’s in Raid 5 plugged to two iMacs, sharing data to about 5 stations (Final Cut, C4D, AE, Photoshop, Illustrator etc.) and performance is excellent from the drives though our network infrastructure is a slight bottle neck at the moment (STILL waiting for Mac Pro’s with Thunderbolt to install Small Tree Ethernet NIC to allow full Gigabit to each workstation – current setup works ‘adequatly’).

    The issue we’ve had with the setup is the intermittent R6 drive ejects which out of the blue. {This] seems mainly to affect the mid 2011 27″ iMac and it should be noted that the Pegasus R4 & R6 compatibility list does list the 21″ iMac as supported but NOT the 27″ iMac.

    Also apparently some people have found some success in wrapping the Thunderbolt cable in _aluminium foil_ which I’ve heard also serves to protect the system from invasion by aliens from outer space. So not all bad news!

    This is documented extensively in the thread below and it seems to affect mainly the mid 2011 iMacs and possibly have something to do with a mobile phone / other electronic signals near the Thunderbolt cable / drive. There is no news as of yet wether it’s an Apple or a Pegasus issue but I’m betting the former as people with MacBooks and Minis seem to have very little issue with these drives.

    There are also third party’s creating RAID boards for these drive and enclosure companies. If you saw press for IBC or IDF this year you would have seen that ATTO technology, the company that makes the great HBAs and RAID Adapters I use in editing is also creating a Thunderbolt RAID product as well! That gets me excited.

  13. Bruce Dec 13, 2011 13:39

    What about adapter solutions, so I can plug my USB 3.0 disk into a Thunderbolt port? Or eSata? Anything like that available?

  14. Larry Dec 13, 2011 13:45

    Available? Well, if you attach an Apple monitor to your computer via Thunderbolt, you can use the ports on the monitor.

    However, standalone adapters are in process, I’ve been told, but not yet available.

    Just a small point to correct: Promise succeeded Apple’s Xserve RAID with their vTrak RAID. Xsan is software, is still an Apple product, and it is now included in OS X Lion.

  17. Larry Dec 13, 2011 16:02

    Thanks – I always appreciate getting my facts straight.

    I’ll correct the blog.

    I have the Promise R6 12TB attached to a 2011 27″ iMac with the 3.4 GHz Sandy Bridge CPU. I’ve had no detach issues; I just cut a 30 min doc on it.

    I -have- seen an issue where sometimes it can take a few seconds to get a directory in Finder on the drive (it still reads/writes fine during this time) but other than that no issues. I’m seeing about 600MB/sec in both directions on sequential reads and writes and I run at RAID 6!

  20. Dick Applebaum Dec 18, 2011 17:44

    I have Pegasus 12 TB attached to a maxed-out iMac 27 (both bought in July).

    Both are great! The Pegasus could easily be Apple kit — in performance, appearance, quality and UX.

    I have 23 TB of external LaCie drives (3 1TB and 10 2TB) that I’ve purchased over the years. The drives are excellent but it’s a rats nest of cables and external power bricks.

    As to the Pegasus being expensive:

    July 2011 PROMISE PEGASUS R6 12TB-CAF, $1,999.00
    April 2006 2TB Bigger Disk Extreme $1,749.00 $1,749.00

    I can’t say enough good things about the Pegasus and Thunderbolt!

    My 16-year-old granddaughter, Marlowe * is learning FCP X and doing some pretty interesting things.

    * Marlowe’s mom is a Bogie Freak

    Marlowe figured out, on her own, that she needs to do storyboarding before shooting…

    Looking for ways to assist her, I suggested that she watch the 2reel guys videos and define the 5 most important she learns…

    She just watched the 1st episode and is quite impressed — especially with that very handsome actor who first appeared on set.

    Long story short!

    There is a whole new generation of “video creators” coming on the scene and a lot of powerful and inexpensive tools to help create them (including tutorials on how to use the tools).

    What appears to be missing is a top-down view of what needs to be done [to create a video[ and how to go about getting it done.

    Will the 2reel guys series be expanded to address this?

    I can see a great need for this… and it could be offered as an online course.



  22. Larry Dec 18, 2011 20:09


    Norman and I are casting about for new ideas for the 2 Reel Guys ( – and your suggestion is very welcome.

    I’ll share this with Norman.

    I am confused by the statement, “Ivy Bridge is the second generation chip I mentioned . . .”. I thought Ivy Bridge is a processor for computers, which I can see helping bring Thunderbolt into more computers (i.e., PC’s). But I don’t understand how Ivy Bridge will help us get more external hard drives and RAID’s with Thunderbolt (i.e, for our current Mac’s with Thunderbolt.)

  24. George Dec 20, 2011 12:06

    Have you checked out Caldigit? Their products and support are solid and they sell a thunderbolt adapter for their RAIDS. I’m not familiar with their whole line but the HDPRO2 (which is based on PCI-E technology) just “adapts” without having to convert anything. I haven’t made the switch to Thunderbolt yet but have been very happy with their products that I do own.
