Oh well, thankfully we still have acess to USB3.0 and eSATA adapters which are a lot more common, nowadays...

Well, They are a lot more common than Thunderbolt, DUH! Thunderbolt was just announced yesterday!
 
Well while that makes sense it's also disappointing about the lack of an expansion for my 2009 MP. Looks like I have another two years before I can take advantage of it then. (Business depreciation naturally)
 
I am going to have to wait and see. The times have always proven to me that there's never really a limit in technology, just a lack of interest or desire or market need from the parties involved if you know what I mean. Since TB is using the PCIe x4 lane, and we already have plenty of bandwidth options as fast or faster than 10GBps in ethernet, FOE, and Fibre channel, there may not be much of a limitation on creating a TB card . . . . even if it only got us half of the proposed bandwidth.
It requires a lot of onboard hardware to implement beyond data only. You may be able to pull it off using Lucid's Virtu hardware to hot swap between an onoard IGP and GPU regardless of brand, drivers, or changing display connectors.

Once more that is more hardware logic to throw into the mix.
 
Voltage?

Anyone has any ideas about the voltage of Thunderbolt? The only information I can find is that it can power devices up to 10W. I would assume 5V to make it easier to build USB adapters but I might as well be wrong.

Or is the voltage really unregulated? This would require each Thunderbolt device to have its own voltage regulator...
 
It is actually MegaBYTES per second they were measuring and not MegaBITS.

Does any one else wonder how well the current disks inside a Macbook pro even with them being SSD could saturate this port?

Surely it can't copy files from one macbook to another (even if both equipped with SSDS) at anywhere near 700 MBPS?

Remove your optical, slap a couple of these babies in there (RAID-0):

And you will saturate the (one channel) of the TB bus.

Unregulated is possible. Firewire is unregulated.

Mini DisplayPort can supply 3.3v at 500mA (less than 2W). Perhaps there are separate connectors that expand this capability, or maybe that 500mA has been up-specced.

I haven't seen any details - but if I had to put money on it, I'd wager 12v or 18v, just to keep the current down (3A at 3.3v is a lot for such a slim cable). An 18V 0.5A line in addition to the 3.3v would make sense.

I read your posts because they are simple, to the point, logical, and not filled with a lot of verbiage.

I can see a lot of issues going on with any device that would have to manage all of that firmware hardware and software.

I'd like to see Drobo take advantage of this Thunderbolt technology.

Same here. Because unfortunate for some, I actually have a speedy Drobo S that's running circles around my G-Tech drives and LaCie RAIDs with only FW800 as the I/O

I haven't even tapped into it's potential with eSATA and would love to have a 6bay Drobo enclosure.

can we connect two different computers with thuderbolt?

probably not, it's a PCI-bus, I don't think it has network capabilities (maybe in the future)

From reading the technical documents it does appear that it's not practical or possible to make thunderbolt a retrofit for existing machines.

This explains it pretty well I think:
http://www.macworld.com/article/158145/2011/02/thunderbolt_what_you_need_to_know.html

I've needed this standard for years because I work with music with lots of track and sometimes HD video with it.

That being said, now you people without TB know how I felt with my G5 tower after the "We're switching to Intel" announcement.

It's not the end of the world but eventually you'll see this was the wise thing to do.


Kind of offensive...you people?!?!?!?!? I was in the same boat and I felt the same way then like I do now.

True, but FCP is pulling from the source files on the Promise to create the composite image, and that image can be played back in full uncompressed 1080p. The engadget guy might not be smart enough to set the app for those settings, but it is stellar speed.

Not to mention, that it's pulling the four streams from the Promise, encoding in realtime on the MBP, spitting it back out on the canvas for FCP and the 27" ACD without any dropped frames.

TB is a nice step up from FW800 and in lots of ways eSATA since the bottleneck in many HD edit rigs was the I/O.



There is such a thing as a G-Technology TB drive? Link please :cool:

On the side, the sucky part about TB for current workstation owners is that they've spent $5000 for a decently equipped Mac Pro and are going to feel that lack of TB hurt down the line. Any company with the budget and the mind power WILL make a TB PCIe card for them, and most likely will charge whatever outrageous price they can.

If I were in that camp, and spend the paltry $5000 for a Mac Pro, I would definitely put another $800 or more in for a 2-6 port TB PCIe card.



You said you weren't sure if there was such a thing as a portable SSD drive
 
"notes that while Apple doesn't have an exclusive on Thunderbolt, they have a head start:"

Nice way to put almost nobody has it and support on third party will be very limited al troughout 2011, that isnt a head start thats adding a mostly useless port.
 
Wow. And I still gloat how well my 2008 white macbook works.... ;)

Seeing this and the tread on the new MBP benchmarks - makes me really wish I had a few thousand to spare. I would really love a new macbook pro and two Promise Pegasus storage arrays. One for all my data, and one for time machine backups. I read the drives are hot swappable, So I would implement the time-machine as Raid / failover. Then I could pull out one drive and send it off-site for backup in the case my home becomes a smoking pit.

Really cool potential here. :D

Can't wait to see the pricing on the storage arrays. Have a feeling the Lacie LIttle Big Disk may be the only consumer affordable one. The Promise Pegasus may be out of range. Both due next quarter.
 
No add on cards for backwards compatibility? Wow, that's going to crush any existing system sales of Mac Pros, and other apple systems not yet updated to Thunderbolt... Not to mention the PC market as well... People will just wait now.
 
I am curious when the Pegasus R6 (or R4) are going to be available - I don't see them anywhere except described on the Promise.com website. That is the RAID he is using in the video. I'd also be interested in knowing if it was RAID 5, 0, 1 etc.

( http://www.promise.com/storage/raid_series.aspx?region=en-US&m=574&rsn1=40&rsn3=47 )

When the Mac Pro's arrive with TB, I expect those will sell quickly - and maybe even for the MBPs.

Q2 - both Lacie Little Big Disk and Promise Pegasus are saying summer (which could stretch all the way till September.

Interesting is, both a saying they will be in the Apple Stores. I can see that with Lacie; but I never seen a storage array like Pegasus in an apple store (USB, or SCSI). I am wondering on pricing for these. I read the Lacie one will feature two 512 SSD drives to make up the 1TB. That is going to be expensive.
 
Thunderbolt looks like a real winner to me. I'll be interested to see if we see licensing to AMD for Thunderbolt and the mini displayport connector to monitor manufacturers in the not too distant future.

Very elegant piece of technology.
 
Ok people complaining about battery life, Clearly you don't watch keynotes or read the fine print. Its wireless web testing. check out
http://events.apple.com.edgesuite.net/1010qwoeiuryfg/event/index.html
at 1:17:00 Steve Jobs explains the new testing, I'm bored so I will quote him.

"The PC Industries battery tests sometimes don't reflect real world results, and we're moving towards some more stringent tests that really we think are going to bring us much closer to real world results on battery tests. Even using these more stringent tests we're getting 7 hours [in the macbook air] wireless web battery life, our previous macbook air using the old more liberal test got only 5."

So thats why you see a jump from 10 to 7. And also when you compare to say a dell or HP, their batteries usually last half of what they say (In my experience). So if I can get 6-7 hours on my laptop surfing the web, thats still pretty awesome.
 
time machine backup's are mostly limited due to two facts.
One: hardrive have a maximum sequential read/write cap (wouldn't be much more in the than 80 MB/s in the 5400 rpm 750 GB HDD).
Two: backing up is most of the time NOT SEQUENTIAL, so in real life you'll average at around 5-15 MB/s.
The time capsule itself even seems to cap at only 15 MB/s (read/write, not throughput/network connectivity).

TB/LP = 10Gb/s raw throughput ~ 900MB/s usable throughput
USB 3.0 = 5 Gb/s raw throughput ~ 150-200 MB/s usable throughput
GBase ethernet = 1 Gb/s raw throughput ~ 90-110 MB/s usable
Firewire 800 = 800 Mb/s raw throughput ~ 80-100 MB/s usable

Backing up will not go any faster using TB in comparison to quite a lot of more frequently used connections.
The power of TB is the extendability of your computer with PCI periferals, without the common high latencies, the scalability, the usage of external storage as a internal. Except for the multiple display you can now easily connect to your mac/pc using just one port I don't expect to see soon any consumer products that'll use TB as a necessity.

So glad you said that. I think quite a few people are going to see this and not realise that the harddrive is going to be a massive bottleneck. Especially with that guy in the video saying "700 Megabytes per second!" when actually he means Megabits per second.

A standard PCIe card can't support Thunderbolt, because of slowness bandwidth (v3.0: 1 GB/s (8 Gb/s). Wikipedia: http://en.wikipedia.org/wiki/PCI_Express

But a 16 lane slot actually can:
A PCIe x4 slot has a 32Gb/s bandwidth. Well, when boards with v3.0 come out anyway.
