Pros: 1. Amazing speed: Read: 365.26 MB/S, Write: 308.48 MB/S. 2. Metallic appearance, durable. Cons: 1. Price is high. 2. Overheat, even though you just plug in the computer. 3.Overall size is bigger than other USB 3.0 flash drive.

I have purchased a few of the SanDisk Extreme Pro 128GB USB 3.1 Flash Drives now, and have been VERY happy with them! Fast speed makes large data transfers happen quickly. High quality case seems to be very durable. I have been a fan of SanDisk USB Flash Drives for years now, and wouldn't even consider anything else! A bit pricey, but you definitely get what you pay for with these drives!

Pros: SSD Performance in a thumb/flash/USB drive, awesome design, USB 3.1, excellent build quality Cons: none Other Thoughts: the Thumb Drive does get very warm under mid/heavy use but it's normal for this kind of USB Drive so don't worry about it ATTO V3.05 Benchmark scores USB 3.0: 425 MB/s Read, 394 MB/s Write USB 3.1: 432 MB/s Read, 396 MB/s Write I don't see much big difference between using USB 3.0 and 3.1 on my ASUS Z170 Hero by switching USB Ports, also it will run just fine on USB 3.0

This is my third 'professional' line SanDisk flash drive and I have to say that I am impressed with the performance. Even though it is a USB 3.1 drive, it operates optimally in a USB 3.0 port. Just take precaution when handling this drive after copying large amounts of files as the drive itself gets VERY WARM to the tough and requires for you to let it sit for a minute or two post useage before safely removing from the USB port. Pick one up when it's on sale and you won't be disappointed.

Great product that is easy to use and very reliable. Just plug it in and use it. Great capacity and fast speed. Impressive speed and capacity.
