The stick doesn't look like the description shows, it's not polished but rather matt. Sequential and random read/write speeds are too low for 2020, more like USB 2.0 flash drives. Writing a large file is quite slow and has a lot of speed drops and pauses. All this is clearly visible in the attached screenshots. The only plus is that the flash drive does not heat up, which is not surprising at such low speeds. I would not recommend that. Instead, it's best to add some cash and look out for well-known brands. I personally bought this flash drive just out of curiosity and for my collection.
