Great USB stick with massive storage capacity

I have the USB flash drive with 256GB, 238GB usable are approx.
Have him get me, I have to move a lot of files.
When you move, or copy down I up to 200MB / s (SSD present in the computer)
When I plug it into your notebook directly and he is so moved about 100GB very hot, but I include a cable between them, so it is only moderately warm. Obviously because of the aluminum case of the notebook. The cap holds after about 2months "duration and deposed" still very good. What is, however, yet I noticed the copy, which is the read / write rate varies greatly. Average I 150MB / s sometimes up to + 200MB / s then only 3MB / s. Weis not whether it is on the drive or on the computer. This phenomenon occurs everywhere I have infected him. That's why there's 4 stars.
All in all highly recommended the stick when searching an external hard drive replacement.
