Why Thunderbolt is a game-changer

Today Apple released brand-new MacBook Pros with Intel's LightPeak technology, now called Thunderbolt.

Thunderbolt is a 10 Gbps port that can daisy-chain up to six devices including a display. To give you an idea of how fast it is, USB 3.0 is 5 Gbps, Firewire 3200 is 3 Gbps, eSATA is 2.4 Gbps and Fibre Channel can be up to 4 Gbps.

To me, this is a game-changer because these ports can become any type of port as long as you have an adapter, so Apple essentially added support for USB 3.0, eSATA and anything else you like in one go. Thunderbolt is a huge leap forward for professional users. Its power is in its versatility.

It also means that laptops can finally rival desktops in I/O performance. As an example of the amount of throughput you'll be able to get on a laptop, Apple showed a demo of Final Cut Pro running four streams of uncompressed HD on the 15" MacBook Pro, peaking at 600MB/s.

And if you're in a shared environment you'll be able to easily add laptops, or indeed any type of Mac, to an Xsan network for fast access to shared storage, which is something that was difficult to do before.

Finally, Apple posted some new details about Mac OS X 10.7 Lion today and revealed that the desktop and server versions of the operating system will be merged together, meaning that every Mac is now a server out of the box. Couple that with Thunderbolt and the Mac Mini suddenly looks reasonable as an Xsan metadata controller (and indeed for many other server tasks) now that the Xserve has been discontinued.
