probabil ca sunteti curiosi de viteza unui XO cu un external HDD. un user care a primit invitatie sa foloseasca beta-ul noului update a postat niste informatii pe neogaf:

I am one of the Beta testers for the June Xbox One update that add's the ability to use up to 2 External Hard Drives. I am using a Seagate 4tb Self Powered Hard Drive. Since I was not 100% sure about using a USB powered drive, I went with a self powered drive just toe ensure no issues.

When I first updated and installed the HDD the system detected it immediately and prompted to format the drive. After doing this, I started to move games over from the internal HDD to the external. When I booted up Forza 5, now running off of my External HDD my Wife said that it seemed to load up faster. I also noticed this, but did not time it. We have 2 Xbox One's in our house and I have the same games loaded on both, so we decided to test it on one of the games that I feel has very long load times, Ryse: Son of Rome.
