Pros: Small size - fits anywhere speed is fine - both read & write

Cons: All Plastic

Overall Review: For what I wanted this is perfect. I put a bunch of music on it and plugged it into my car. Its small size will keep it out of the way. I will not be moving it from multiple devices often so it works for me. It is all plastic - so it is not super durable. If you are planning on plugging and un-plugging often I would get a different device.

Pros: -Cheapest USB 3.1 (10G) drive for this size on the market

Cons: -Flimsy plastic that started to crack after less than 6 months -Frequently requires plugging and unplugging, sometimes multiple times, in order to be recognized by a device -Transfer speeds vary wildly. Doing a write from my laptop to the drive using a USB 3.0 (5G) port, speeds cap at ~50MB/s and can be as low as 10MB/s. Even cutting in half by not using a 10G port, that's far from the advertised speeds. -Reading high bitrate 4K x265 files (~40Mbps video, so 5MB/s in bytes) from the drive onto my Xbox One X frequently causes stuttering and dropped frames that I don't get from the same video played off internal or external HDDs.

Overall Review: It wasn't a giant waste of money, thankfully, but I definitely regret this purchase. I had an old PNY drive that was 128GB, but was pretty slow since it was USB 2.0. I expected a massive improvement over that drive which I didn't get here. I've had good experiences with Sandisk microSD cards in the past, but I don't think I'll bother with their USB drives again in the future. Whatever brand you go with, I would recommend getting something a little more expensive (and probably a little less tiny -- this thing is impractically small, and that's probably part of why it's so fragile).
