Hi, I bought the USB stick as a replacement for my 8 GB USB flash drive a cheap manufacturer. My old stick came only on a mere 300 kb / s, with the Lexar it comes after all, with fleets 6-7 MB vorran to a USB 2.0 port. This speed he keeps the whole transmission time. He unfolds the full power to a USB 3.0 port. Only today I have come to enjoy the 30 MB / s when I transfer data over a USB 3.0 port! Superclass gigabyte folder are transferred within moments! The fuel gauge I use rarely, who needs it will certainly know to appreciate. The door I like that you do not lose it Dissolved, but a "flipping" as it can be found in the other models, there is not. Thus, the USB flash drive is not unnecessarily large in the open state. Full buy recommendation!
