USB3 key and a miniature performance in reading. Progress over the model "Hook," but not write speed of

Jai tested there about 3 months the model "Hook" PNY 32GB. After comparing the T3 key to the key "Hook" my first reaction was to métonner of the rapid progress of PNY. But, really, if I go to marketing dates by Amazon, it seems that seven years separate these two models because the Hook key was on sale in 2008 while this key T3 nest on sale since this year .

Certainly the Hook key that javais tested has a capacity of 32 GB while the T3 key I just tested has a capacity of 16 GB, but the information provided on this website we learn that dimensions and speed performance does not depend capacity, this key also has a 32 GB and 64 GB.

In short this key T3 "Attached" is two times shorter than the key "Hook" that mavait already impressed by its small size, and the read speed is more than 2 times.

More precisely:
1. The length of the key "Hook" is 46 mm and the length of this key is 23mm.
2. Performance:
First of Jai transferred 5GB of video from my PC to the T3 key. The speed décriture was 8.5 MB / s, which is far from the 20 MB / s maximum promised, and this is a little worse than the speed décriture 12.5 MB / s that javais observed with the key "Hook ".
Then i transferred the file to 5GB computer: there performance (read so) are very much better, namely about 110MB / s (under 10s for 1GB), which corresponds approximately the maximum.

Finally i compared the performance of this key to those dune key USB3 SanDisk Extreme 64GB which i recently acquired: the reading performance is the same, but the write performance is very much to the advantage of SanDisk is the order of 20 times faster. But this is not miniaturized SanDisk key.

Note: This key is called "Micro USB3," which might suggest that the micro USB connector is on Smartphones such as for example. But nen is nothing: it comes of a conventional connector USB3, no micro type. The qualifier "Micro" probably refers to the size of the key.
