Summary: Lots of reviewers seem to indicate that it's a really fast drive, that is not entirely true. The write speeds are abysmal before 64K. After that it picks up, but for me it only got to about 70-100 MB/s (in ATTO) for the writes and all over the place for the reads between about 130-160 MB/s.
Pros: It isn't dead
Cons: slllloooooooowwwwwww writes up until 64K speeds were all over the place in ATTO
Summary: There is firmware bug on this USB thumb drive. When Windows hibernates and wakes up, it does not see this drive. I have never had that problem on the (Kingston HyperX 3.0) 64GB version as far as I remember. Other than that, the drive is great with very good capacity.
Summary: Solid construction. Great looking. Good use of rubber for grip. Love the blue color. Oh, did I mention that it was fast? It's the fastest USB 3 flash drive that I own and it is FAST! The only thing I wish it had is some sort of a lanyard or attachment for the cap.
Summary: don't believe me, go to a manufacturer's website. they often will explain how they measure capacity.
Pros: mfr's define a kilobyte as 1,000 bytes so they give capacity as 10 to the x power (industry standard). thus 1GB is 10 to the 9th power or 1,000,000,000 bytes the computer defines a kilobyte as 1,024 bytes. so they give capacity as 2 to the x power. thus 1GB is 2 to the 30th power or 1,073,741,824...
