With the announcement of new MacBook
Pros this morningcame the news that Intels Light Peak technology is now known
News hit yesterday that
Apple would likely be the first company to adopt the new I/O technology, which
is capable of incredible speeds of 10 gigabits per second in both directions.
Thunderbolt ports will look like the existing Mini DisplayPort connection on
older generation MacBook Pros and will sport a lightning bolt icon.
According to Intel, Thunderbolts speeds will allow users to transfer a full
high-definition movie (between 10 gigabytes and 20 gigabytes in size) in less
than 30 seconds.
The technology allows external devices to tap directly into the PCI Express
interface on computers, which allows for the incredibly fast transfer speeds. As
with FireWire devices, it will be possible to daisy-chain multiple Thunderbolt
devices together, which means computers wont have a need for more than one
Thunderbolt port. The interface also provides power, also like FireWire, so
users dont have to worry about connecting extra power adapters to external hard
Given its speed and bandwidth capabilities, Thunderbolt was meant to serve as a
single interface to juggle multiple functions. The protocol is smart enough to
know what youre intending to use it for for example, it will function as a
disk interface if you plug in a Thunderbolt-capable disk drive, but if you plug
in a Thunderbolt monitor, it will instead function as a display interface.
Other PC manufacturers, including Sony, are expected to adopt Thunderbolt later
this year and into early 2012.
