Summary: Ordered this drive in June 2013 and have loved it since then. Blazing fast speeds (I can copy large files quickly and lots of small files quickly, sorry no actual numbers). I really enjoy this drive.
Summary: Haven't done any speed tests on it but its fast, -- very fast, and hasn't given me any issues. I use it to transfer files from my MAC laptop to my PC and also to play videos and music on my media setup. Works like a charm every time.
Summary: These flash drives were obviously designed for USB 3. Transfer speeds are exceptional. Benchmark tool actually showed better performance than the system's 7200rpm SATA 3 hard disk. It doesn't make sense to buy a huge flash drive if it takes hours and hours to move data to or from it.
