150 MB/sec? All it did for me, backing up 10.5 GB of small folders/files, was 1 MB/sec. And the warranty - they wouldn't send replacements unless I mailed them the bad drives first, which means I would lose my all-important backups.

I purchased this flash drive not having 100% confidence that it would live up to its spec, but I was pleasantly surprised. Although the body on the drive is flimsy in my opinion, the performance is excellent. I have tested a few flash drives using CrystalDiskMark and this showed the write performance of the SanDisk Extreme Go outperformed its younger brothers (SanDisk Ultra Dual Drive) write speed by more than 4x. The Ultra Dual writing at 35mbs and the Extreme Go writing at 144mbs. This was with the drives plugged directly into a USB 3.0 socket on the computer. If you plug it in through a hub, this will likely be considerably lower. I have mostly cheap ebay flash drives and the best write speed I got from them was 20mbs (which wasn't far off SanDisk Ultra Dual ... MoreI purchased this flash drive not having 100% confidence that it would live up to its spec, but I was pleasantly surprised.

If I could give half a star, I would have given 4.5 out 5.0, purely because of the flimsy casing, although the USB connector mechanism is very robust. This is obviously my opinion, but flimsy plastic aside, I personally would still recommend the SanDisk Extreme Go, merely for its performance.

Pluses: Powerful features on the box. Minuses: Inconsistency of theory and practice. Description: I bought SanDisk Extreme Go USB 3.1 (128 GB). The fact that the volume is always less is understandable, and the fact that it is warming is habitual. But real speed is a shock: - writing: about 30MB/s (+/-2MB) for real files from 2.0 to 5.7 Gb - reading: about 130MB/s, but somewhere after 4GB, the speed drops to about 80MB/s If it does not suit you, do not buy it. And do not look synthetic tests and other reviews!

Mechanical design OK. Fast read speed.But Sandisk forgot to tell that the write speed - up to 150MB/s - only can be achieved on platforms supporting UASP.It's an expensive flash drive, when providing USB2.0 write speeds only.Go for Lexar P30's instead.
Write speed about 110MB/s in Windows with large files which is slower (160MB/s) than the previous Extreme 3.0 series. Oddly only 50MB/s when writing to sectors during testing, maybe some cache magic going on somewhere? No SMART or temperature information unlike the PRO version. But it is cheap at least here and these issues may not be critical for most people.
Use it for the 'TimeShift' function on Smart HDTV. Works really well. The occasional jittery movement I experienced with a Corsair USB3.0 memory stick has disappeared. Maybe that's due to some minor incompatibility between the TV and the Corsair stick or perhaps it's a speed issue as the ScanDisk specification states faster read & write speeds. Too early to judge reliability.

This is by far the fastest at Sequential Writes and reads and has excellent build quality. Can run a live OS from it or move huge Gigabytes of data in seconds or couple minutes. No long waits no BS.This is a sturdy ultra fast USB 3.1 level chips etc that is what USB 3 should be. Perfect for backups and projects. Pro level video production speeds etc.
