In early 2011, Intel introduced a new peripheral device connector called “thunderbolt” in the updated Macbook Pro notebooks made by Apple. This device was formerly named “lightpeak” and was supposed to offer data transfer speeds across various devices at 10 to 100 times the speed of USB 2.0 peripheral device connector.
Intel has been working on this device since 2003 and wanted to use optical fiber cables for extremely high and secure data transfer, but the cost of designing and manufacturing optical fiber cables is still very high so they cannot be introduced in the consumer markets for connecting peripheral devices yet.
Therefore Intel used copper wires for transferring data. Thunderbolt is more advanced than USB peripheral transfer technology, and it can transfer data up to 25 times the speed of current USB2.0 technology. USB manufacturers and researchers have now created USB3.0, a third generation data transfer specification which can transfer data at 5 GBit/s, which is half the data transfer speed of “Thunderbolt”, rated at 10GBit/s.
Many technology analysts are predicting that Thunderbolt will eventually replace USB3.0 and Universal Serial Bus technology altogether in the next few years. This may or may not come to pass, since there are pros and cons in the implementation strategy of Thunderbolt.
Intel is the 800 pound Gorilla of technology and almost 85% of all processors for computers in the consumer market are made by Intel. Such a dominant market share makes it really possible for Intel to introduce thunderbolt in large enough quantities through four or five dominant computer manufacturers such as Hewlett Packard, Dell, Acer, Lenovo, and Asus to replace USB3.0 as the dominant standard in the market.
However, other analysts are not so sure and they believe USB is here to stay and might continue to evolve with higher bandwidths and greater data transfer security. This might lead to a situation where both Thunderbolt and USB continue to co-exist.
