Model overview based on user reviews

The SanDisk Ultra USB 3.0 flash drive, specifically the 32GB variant, has received mixed reviews from users. While the assembly quality is noted positively, the product suffers from unstable speed issues, with data transfer rates dropping significantly from 50 MB/s to 7 MB/s during large file transfers. Additionally, a major concern is the strong heating of the device, reaching temperatures of 50-55°C, which occurs both during active use and even when idle. Due to these issues, users have expressed dissatisfaction and do not recommend purchasing this model.

model with serious drawbacks

10 April 2019

The model is completely crap, the speed consistently drops to the end of the data transfer from 50 MB/s to 7 MB/s at a volume of 1 GB, and the saddest part is that it gets extremely hot, 50-55°C, both during reading and writing.
