Summary: I love this small drive, no complains at all. Recommend.
Pros: I've been using this flash stick for about a month now, but had the same model with 8 GB capacity before. The speed is descent, I got around 8 Mb/s in average. Good design so you won't lost the small cap. It also looks premium.
Summary: Test performed once by Parkdale 2.94 free test software, on a USB3 port. Non-scientific (only done once). Seq. Write Speed: 18.3 MByte/sec Random QD32 765.7 kByte/sec, 191.4 IOPS, 5.22 ms Seq.
Pros: Speed appears fast
Cons: Cap is not attached to the device to prevent it's loss. There is not a ring on the device which would allow attachment to a key ring or badge holder type rope.
