Apple's MacBook Pro laptop, you may have noticed that there is a new interface with a lightning bolt next to the mini DP interface on the side of the new MacBookPro. That's right, this is Apple's latest Thunderbolt technology.

Thunderbolt technology comes from Intel. This technology was first applied to MacBook laptops. Thunderbolt is a high-speed interface technology for personal computers. It has a data transfer speed of 10GB/s. It is the current USB3.0 interface. Times.

But the current Thunderbolt interface is not popular. Before you decide to purchase Thunderbolt devices, let us take a look at how Thunderbolt will change the future data transmission mode.

Light Peak's milk name is Thunderbolt

Thunderbolt technology was designed by Intel in 2009 and named "Light Peak" (Thunderbolt is a research and development code). Thunderbolt was originally developed to replace and unify the numerous expansion interfaces on the computer, such as SCSI. , SATA, USB, FireWire and PCI Express.

Why do you need it?

At least for now, Thunderbolt is not a necessary interface, because there are currently few devices that can use this interface, but in the long run, Thunderbolt will inevitably reduce the user's troubles in the future, because Thunderbolt can replace almost all expansion interfaces.

Perhaps some old Apple users still remember the controversy that Apple still gave up when it gave up the FireWire interface. Users had to purchase a patch cord to connect to the FireWire device. In addition, Apple also canceled the ExpressCard/34 interface. Today, Apple may have been a long time ago. I started thinking about connecting all the devices with one interface, and I started to reserve space for Thunderbolt early.

How does it work?

The Thunderbolt interface needs to integrate a dedicated control chip on the motherboard. Intel said that the Thunderbolt interface does not have to use Intel CPU. In fact, Thunderbolt is more like an adapter because it actually connects PCI Express x4 and DisplayPort bus at the same time. The former is used to transmit data and the latter is used to transmit video. Thunderbolt allows two channels to transmit two streams simultaneously in the same direction, and the data transmission speed can reach 10GB/s.

Who supports it?

While Apple released the new MacBook Pro with Thunderbolt interface (the lowest online price of 245.0 yuan), many brands announced that they will launch Thunderbolt related products, including Aja, Apogee, Avid and Blackmagic.

The key to the success of the Thunderbolt interface for external storage devices is that Intel and LaCie will offer mobile hard drives that are compatible with Thunderbolt interfaces. LaCie has even decided to launch a Thunderbolt interface this summer.
