Microsoft has defined why its vary of Floor laptops and tablets don’t have Thunderbolt ports or detachable RAM: safety considerations. That element was revealed in a Floor engineering webinar leaked on Twitter by WalkingCat, whereby a Microsoft worker lays out all of the engineering concerned within the firm’s newest units.

“No Floor gadget has Thunderbolt. Why not? As a result of that’s a direct reminiscence entry port,” explains the Microsoft worker. “When you have a effectively ready stick that you would be able to put into the direct reminiscence entry port, then you possibly can entry the total gadget in reminiscence and all knowledge that’s saved in reminiscence. We don’t imagine, at this second, that Thunderbolt can ship the safety that’s actually wanted from the units.”

The Verge has verified that the presentation is real, and that the Microsoft worker is a Floor expertise specialist primarily based within the Netherlands that has labored on the firm for greater than 10 years. Within the hour-long presentation, it’s additionally revealed that Microsoft’s Floor units don’t have detachable RAM as a consequence of comparable safety considerations.

“Should you’d be capable to improve the reminiscence… what you possibly can simply do is freeze the reminiscence with liquid nitrogen, get the reminiscence out, after which put it in a selected reader… after which you possibly can entry all the info that was loaded into reminiscence,” explains the Microsoft worker. “That’s why on all Floor units the reminiscence is just not bodily upgradeable, due to safety. We wish to be certain the reminiscence cannot be tampered with.”

We requested Microsoft for a touch upon the presentation, however the firm says it has nothing to share about it. Different comparable business-focused laptops from Lenovo, Dell, and HP have used Thunderbolt for years, however Floor units have at all times been an outlier.

It’s shocking to listen to Microsoft blame safety for the shortage of Thunderbolt ports moderately than incompatibility with its personal Floor Connector. Microsoft’s propriety charging connector doesn’t assist Thunderbolt, and its excessive knowledge switch speeds, nevertheless it does supply the distinctiveness of information switch, energy supply, and video assist all in a single cable with magnetic positioning.
