It has a read speed of 130 mBps so unless your video is encoded at more than 1 Gbps it shouldn't be any issues. The heat dissipation though is non existent because of the small size which is why I returned it. I was afraid it might burn the usb port on my laptop
I had the white version of this for my Ultrabook and the temps on ti were ridiculous. I ended up returning it and replacing it with a Samsung ultra fit drive that runs much cooler.
Warm you up.
