The only true thing is prices are 30 during the promo for 64GB really worth not more given the competition. Because if not an extra key. about 82Mo / s drive and only 10MB / s write a low-end wrench made. My Corsair 32GB traveler is 2 times better write 20MB / s and 75MB / s read. And Verbatim V3 max 64GB 175MB / s read and 80MB / s write (lifetime warranty)
Basically these 3 keys 64GB is in the same price range ...
