Microsoft explains why Surface has not been equipped with Thunderbolt interface
The speed of Microsoft adding Type-C interface to the Surface product line is relatively slow compared to other manufacturers, and when the Surface product line finally has a product that adds Type-C interface, this product does not support Thunderbolt. Thunderbolt technology (compared to ordinary transfer protocols is faster and can also be connected to hardware such as graphics cards), which undoubtedly disappointed some Surface fans.
Recently, Microsoft explained this in a security-related report, and explained in general why the Surface product line has not been equipped with a Type-C interface that supports Thunderbolt technology, and why the devices of the Surface product line can’t upgrade RAM.
The first is the description of Thunderbolt technology. Microsoft said that because Thunderbolt technology uses DMA (direct memory access) technology, hackers can directly read and write devices through the Thunderbolt interface without hacking the operating system and processor. This will undoubtedly allow some hackers to directly read any data in your device’s memory (such as Bitlocker keys and other encryption keys) by cracking the device, and even say that malware bypass the lock screen.
For the same reason, Microsoft also soldered the memory of all Surface product line devices to the motherboard, because if you don’t solder the memory to the motherboard, hackers can use liquid nitrogen to save the memory data. Attackers use an external memory reader to obtain important data such as encryption keys.
Although these security-related examples cited by Microsoft are actually present, in fact, most ordinary users do not care about this, and if a hacker wants to hack a computer, he certainly will not only have these two methods.
