To USB or Not to USB


Thunderbolt vs. USB 3.0 Part 2

I highly recommend reading Rick Merritt’s article 10 things to know about Thunderbolt to understand Thunderbolt.

I recommend another article from Merritt talking about USB 3.0 and Thunderbolt.  I think Merritt’s article is correct in terms of slowing the adoption of Thunderbolt.  (His writing is also excellent).

For Apple, the use of the DisplayPort for other connectivity makes sense.

1) It keeps the small form factor of the DisplayPort

2) It bridges to other technologies, like USB 3.0

So that means your Apple Monitor will have a USB 3.0 Hub inside of it that will connect to a DisplayPort Hub. And your Monitor becomes your docking station.

There is the weird challenge from AMD in an XBIT article regarding Thunderbolt.  The article states that the bandwidth of Displayport is already saturated with Displayport data, so you can’t put more data across a Thunderbolt line.  I really don’t know because I haven’t seen any specs.

1) If the data is somehow multiplexed on the standard DisplayPort lines than this might be true.

2) If the data is on separate lines, this isn’t the case.

I also received this interested article from MCCI on Thunderbolt and security concerns.  The article says that you could basically walk up, plug something into a Thunderbolt port, and somehow grab the data.

I haven’t a clue, but I actually believe that it will be no different than any thing else. It is more likely someone will just walk up and steal your laptop or portable SSD or phone or flash drive.
