Personally, I have only used it for small document files and significantly larger ones with photos and videos, up to that point. As for those, I am very satisfied with the transfer speed. The transfer is done in a breeze, even if we're talking about 250 photos, for example. I haven't found anything negative.

I bought it with a specific purpose, to use it to load additional games on the PS Classic. Although the console has a USB port, its construction is for a controller and it does not provide enough power, resulting in very slow reading and many times it does not load at all, even with a smaller capacity USB. Having tried various others, this particular one was the one that did the job.

Although I had researched its specifications in real conditions based on speed, when I finally got it, it had nothing to do with what I had seen. Its speed in writing is 0 to 10 MB/s, and I say this because for less than 1 second it goes to 10 MB/s and then drops to 0, and this is repeated, resulting in a huge delay in file transfer. At least it has good speed in Read, 21-23 MB/s. From its construction, I expected it to be more durable, and the USB port connection doesn't seem so good. To give a better picture, it takes 10 minutes to transfer a 2 GB file.
