Although the transfer speeds are not very swift but they are entirely satisfactory. Either way the bulk does not seem to me to be, if you opt for this key is above all for its size.
And it is true it really is tiny! A counselor so for all mobile devices at large as an MP3 car radio, a music player, a netbook ... She is so small that it can be better worth leaving the device in order for the transport of avoid loss!
The big unknown is the longevity. So far so good, I will edit this comment if a failure occurs.
Meanwhile if you want a USB key "itty bitty" this model is an excellent choice.
