[M] Toshiba 16GB TransMemory U401 USB 2.0 Flash Drive Review
 

While the Transmemory U401 has a more professional look and durable aluminum body, we were not too happy about its overall performance, especially the one involving writes. The product is falling behind the U201 and the low performance even for an USB 2.0 drive makes it unpleasant even when transferring a lot of small files.
