Firstly, this is my initial review without much testing. I find this usb drive very quick, my previous usb drive was usb 3 but it was a long time (several years) since i bought it so it is a significant upgrade for myself. I wanted fast transfers for lots of small files and this seems to do quite well. I like the metal casing of this usb drive, it feels well built. Only time will tell how good the sliding mechanism will last but it feels ok. I still find the price a little high for what i am getting but then again it is one of Sandisk's higher end usb drives and all of my Sandisk products have always been very reliable.

I copy things to my flash drive when I need to transfer data from one computer to another. I also use it to back up my most important data. This is in addition to my normal backup. Thus, I need as high speed as possible. The Sandisk Extreme Pro USB 3.1 satisfies my requirements in this regard. With lifetime warranty, it should be fairly safe for backup. I have used it for a month without any problems, and it is just as fast as it was on the first day.

I needed a fast stick to quickly transfer large 4K movies onto, and this thing is fast. I have a few 64Gb Sandisk Extreme's, and they are pretty quick, in most cases, but this is faster & of course bigger. And I'm only using USB 3.0, so it might even be faster on 3.1. Nice

Only had this for a couple of weeks but if you're frustrated by how long it takes to load large files onto slow USB1/2 or 'run of the mill' USB3 stick this is the one to get. It's as fast as most external HDD's. Into a genuine USB3 hub a 4GB file takes under 10 seconds depending on the host computer's CPU duty at the time. This is what alls USB3 memory stick should be! Highly recommended.

Fastest thumb drive I have used. Brilliant for large 4k video files. It is about four times faster then my TDK silver drives and I thought they were fast until now. The drive is physically a little larger but this is not an issue for me.
