Cheap key to 16GB USB3. Reading, constant, is approximately 94 MB / s, which is not bad. However, she collapses in writing small files. I had taken to install the system in a NAS, but as soon as I install programs or written on the key weakness is felt (this is the case of many such models that have time significant latency - poor quality of caches). I therefore recommended rather for the exchange of large files where she wrote an average of 30 MB / s almost gigabyte, and around 20 MB / s then.
