I was getting 30-50MB/s initially, but after about the third large transfer speeds are below 10MB/s, sometimes in the KB/s range. No point in a 128GB USB 3.0 Flash Drive when transfer speeds are below USB 2.0 specficiations.

Beside changing the setting to NTFS so I can upload large file nto the flash drive, this product does the job. The price is reasonable and I love the looks. Although, I didn't expect it to be that small so gripping it while inserting it into the PC was a bit challenging. Overall, highly recommended.

Good value for the money for this pen drive. But is slow. I can only get 10 MB/s average transfer rates from the PC to the flash drive over an USB 3.0 port. Also I gets really, really hot as it transfers data from PC to th flash drive.

It is working, but with a questionable speed, and running extremely hot so I use three coins on the top for heat exchange, basically it fills like you can cook eggs on the drive.

I've been waiting til prices came down a bit to purchase a 256GB flash drive, and as you can get some decent 3.0/3.1 drives from reputable companies, I found this one from one of my most trusted brands, Sandisk.
