A little research goes a long way regarding these drives. This one didn't list it's speed, but Verbatim is a very trustworthy brand which is why I chose it over the competition. To unlock the full capacity go to MyComputer>Right Click Flash Drive>Format>Select "File System" to NTSF and other options...
Let me say after owning about a dozen different USB Flash Drives this one is by far the best build quality I've used; It is hard, it feels like it could take a beating, and the slide out USB tip actually clicks firmly in place.
No instructions regarding Fat32/NTSF format options; Basically this card can come up as 4gigabytes without formatting it to NTSF which unlocks it's 59.7 gigabyte capacity; All flash drives advertise a bit bigger then their actual size so losing space should always be expected
