Summary: This drive has great performance. The form factor is a little awkward because of the length, and on rare occasions, certain computers were not able to read from the drive. The cap has no way to permanently attach to the body, so would be just a matter of time before it gets lost. I just took it off and stored it, and in the meantime use the drive with the connector uncovered. Because of the above reasons, I give it 4 stars.
Summary: Capacity calculates as 63.23 GB formatted as FAT32. I gave it 2 stars because the transfer rates vary wildly. Using Blackmagic Disk Speed Test set to 1 GB file size, it will vary wildly anywhere from 15 MB/s to 86 MB/s writing and 3 MB/s to 120 MB/s reading. I bought this to run my Windows 7 VMware file off of (to save space on my small Macbook Air SSD) but it's unusable because of the speed problems.
Summary: This usb is very poor quality, The cap is useless, does not clip in secure, guarantee you'll lose it. Also the metal usb shroud was bent on mine. The usb is also very long so i sometimes could not plug it it in tight situations. And the biggest reason why i had to return it was that after a week the usb transfer speed became very low and unusable.
