Xtra-PC really works?

[MojangYang]

So I saw this advertisement on YouTube about a small USB device called “Xtra-PC”

So my question is: Does it actually work as advertised? I’m somewhat doubtful about that.

and it it actually works, HOW DOES IT WORK?

 

After reading the article, I discovered that this “device” is actually a USB flash drive with a special OS on it, and I was right because when i searched it up on eBay, i saw one that looked just like the Sandisk Cruzer Blade.

 

What the ad said didn’t really make sense. If you are booting from the USB, you are using it’s os. But then why does it work with existing os of your HDD?

 

I don’t understand why a cheap software on a regular cheap flash drive can speed up your pc’s performance.
