I had one of those sticks 2-3 years in operation. He recently broke down, that's probably normal for this life (there really were a lot of read and write operations). That's not so tragic, I have the data backed up on a regular basis. From the speed of read / write nothing to complain about gabs. Property me so then again such a concern. During the first use he still worked without any problems. I have the stick then logged ornungsgemäß after filling, and plug in the next time he was no longer even recognized. Messages: installation failed, error code 10 - Device could not be started. At three other computers the same problems. Therefore only kanns lie on the stick. And now I can not even take the warranty, because I can no longer delete the (sensitive) data. So stick to the ton, and 30 write off! (4 + 0) star / 2 = 2 stars
