Great flash drive. It's expensive, but if you need to move large files frequently, this is the flash drive you should buy. Read and write speeds cannot be adjusted. Many flash drives have excellent read speeds, but this one has both. Lifetime guarantee? Who gives a lifetime guarantee now? This is my second device and both still work. One of them is online most of the day and two years later is still working. The ONLY downside is the thickness of the flash drive. I don't mind the size considering the performance. BUT I have a thin laptop (ultrabook). The flash drive bends a little on the table. Over time I see damage to the USB port. This is only an issue on thin laptops. Likewise, it's difficult to use the closest USB port next to a flash drive. You can't go wrong with this flash drive.
