    i bought this flash drive to use with my macbook pro, 128gb is quite a lot of memory especially since ive used it to store a ton of movies and photos on it, it has very fast read/write speeds so i have no complaints, the design is very nice and compact as well. Would totally recommend to anyone who needs some extra space for saving media and/or backing up their pictures and music
