Everything is said in the title of this review: Kingston this key is exceptional. The first thing that struck me is its design: a key all in blue and black, wide. Although a key does not meet premium standards of beauty First, it's always a plus, especially compared to its life. I chose the key to 64GB, 32GB insofar seemed a tad too little and, instead, the keys of 128 or 256GB would not be useful to me (for volumes, a hard drive is more significant). Consistent with other reviews here yourself, the transfer speed is a big step forward compared to my old USB keys. I have not yet tested the USB3.0 but I'm excited about these astronomical speeds, others have praised.
I also read that some users have complained of the excessive width of the key, which would prevent the use of adjacent USB ports. This is completely false. I could use that key to a good ten different computers, and I have not had a single problem.
In the end, I have no regret this purchase, especially for this price.
EDIT: After nearly a year of daily use, I had no problem with that key: always recognized (Linux / Windows / Channels Hi-Fi / Radio), always quick, always solid. Kingston HyperX is top.
