Review on 📦 VANSUNY USB 3.1 Flash Drive 64GB - High Speed Solid State USB Drive for Fast Data Transfer - Green 64G USB Memory Stick with Zip Drive Functionality by Matt Sirmons

I've used a lot of different flash drives and microSD cards. One of my favorite brands was SanDisk. I've had good success, relatively fast speeds, and decent prices. This drive is more expensive (although I was lucky enough to get it on sale) but absolutely doesn't compare in terms of performance. I've seen speeds in excess of 230MB/s (continuous) when transferring large files. When copying the My Documents directory (with different file sizes), speeds range from 80MB/s to 20MB/s with very short bursts (so fast you hardly notice) of only 8-10MB/s. But other drives I've had in a similar test have sometimes dropped below 1MB/s, sometimes for excruciatingly long periods of time. Your mileage may vary and I don't have the disc yet (a few weeks). So far I have not regretted it and can say a lot of good things about this drive. It seems solid and well made, but if it doesn't last as long as I think I'll try to remember to update this review. I have to mention two small points. (1) On my laptop with adjacent USB ports, the width of the drive does not allow most other devices to be connected to the adjacent USB port. This will rarely, if ever, be a problem for me, but it might be for you. (2) It's getting warm - not hot, but more than warm. Not enough to bother me, but deserves a mention. Neither of these two issues are significant enough for me to downgrade my rating.
