Very fast even on usb 3.0. Results of usb 3.0 sequential speed test was a consistant 265 read/ 196 write. Could not test usb 3.1 as i do not have that function on my pc. Very impressed so far, as i have been pinched with my older sandisk extreme pro usb 3.0 128gb. Highly recommended product.

Very fast speeds and with a nice meaty storage. However this device is majorly flawed due to issues that develop over time with the retractable USB port. It works well until it doesn't. I got 6 months of periodic use until it just stopped working. Never damaged or ill treated and I have read other reviews echoing this same flaw.

Generally good enough and I'll have to use it for a longer time to be able to say its reliability. However a couple of negative things I've already noticed are 1. Its edge of key ring end is too shape to handle comfortably. 2. It gets very warm (heated) only after a few minutes of using it. I think it's similar speed to USB 3.0, not as fast as described.

Very fast, very large capacity - one minor problem (perhaps not so minor - hot to the touch) is that it heats up within a minute or two of use. I bought it to back up a surface pro system but now wonder how hot it will get if I leave it running for 15-20 minutes!

Simply great. Large files are transferred so quickly. Have been using them for a few years now and wouldn't go for anything else.
