First, I have USB 2.0 drives (not USB 3.0). It could be an issue with the Vine program (I should have gotten 16GB USB 3.0 drives, but I have 32GB USB 2.0 drives instead). Judging by the reviews, some people use USB 2.0 and others 3.0. Also, I really like these drives. I like different colors. There is a slot for attaching a key ring. The plastic cover slides to cover and protect the metal USB connector (no cap can be lost), but does not cover the end, so lint and debris can still get into the port. There's no indication of capacity (32GB) on the outside, which can be handy. I am giving 5 stars though because the multi colored 5 pack is great at such a low price for a flash drive. The writing speed (copying a 1GB file TO the flash drive) is 6MB/s and the reading speed (copying FROM the flash drive) is 24MB/s. Thus, it takes less than 3 minutes to back up a 1GB file and about 45 seconds to read it. I'm okay with that as I don't worry too much about speed when using it.
