The USM8GLX is a good USB stick. His writing speed is Windows 7 about 5.5 MB / s with a 1 GB large file. This is only half as fast as the maximum specified maximum value, therefore a half star deduction. The reading rate is good 25MB / s. The design of the USB stick is quite appealing, the housing is made of plastic. In the price range a little higher quality Matrial could be used for this also a half star deduction. For plastic processing is very good. The gold-colored USB port can be one click mechanism in the housing sink, a great idea. The read and write access is indicated by an orange-colored highly visible LED on the "Click" end which expresses looks stylish. So who needs a fast USB stick, we will enable to spend a few euros more and get the Sony Micro Vault Click Excellence 8GB, especially as the warranty is 5 years.
