Are you looking for a Windows PC that has the fastest external data transfer speed in home computing? Orginally desgined by Intel and Apple Computer for their computers, the Thunderbolt technology has been licensed to a few companies, including Acer, for one of its higher-end laptops. Thunderbolt's speed is 10 Gbps; to understand just how fast this is, you can download a full-length HD movie in under 30 seconds. Yep, that's pretty quick.
Thunderbolt vs USB
To put it in perspective to other data transfer technologies, USB version 3.0 is 5 Gbps, so Thunderbolt is twice as fast, although replacing copper with fiber-optic wiring in the interface cables will significantly add to the speed.
Acer Aspire and Lenovo ThinkPad Ege
The Acer Aspire S5 laptop is selling with the Thunderbolt port for about $1300. The Aspire is ultra-thin and light, at 2.6 lbs, and all of the ports are contained behind a motorized door. Other PC makers on the Thunderbolt bandwagon include the Lenovo ThinkPad Edge laptop, and Asus has added it to a few of their laptops as well. The issue right now is that only a handful of companies make peripherals that are compatible with the Thunderbolt standard, although many believe it will be a different story by the end of 2012. Time will tell.
