Quick: Yes! In usb3 I have write speeds of 111MB / s and 192MB / s read! It's fast, very fast!
Without hood: USB retractable, sliding with an effect "Darret notch" which seems solid.
Not too big: Perfect, she goes perfectly well not only deep into my Macbook Pro Retina, but also in width, no associated ports (Thunderbolt, Jack, SD Card) is blocked!
Not too expensive: the 32GB, with all these points positive to 35, it's great!
In short, highly recommended!
