I bought in "Amazon" for 2990r at the beginning of February 2023 (this is the price of their site, we do not take into account bonuses). I have a package without Chinese characters (read reviews): Made in Taiwan - I give a photo of the package on both sides. I formatted it completely in exFAT (not a quick format), then I measured the read / write speed on 2 different computers using the CrystalDiskMark 8.0.4 x64, Win10 utility. On the "old" computer of 2022, the flash drive was stuck into the side USB connector of the new DELL monitor, which itself is connected by cable to the USB_3.0 system unit port - photo. On the new one - the 2022 LENOVO system unit: [Lenovo Legion T5 26IOB6 90RT00RURS] - through a 1.0m cable [UGREEN USB_3.2_Gen1 Type-A - USB_3.2_Gen1 Type-A] to the port on the back of the USB_3.1_Gen2 system unit. The results of measurements - in the photo: correspond to the declared ones. Note: the speed immediately drops if the cable is 2.0! And further. I plugged USB_3.2_Gen1 into the upper ports on LENOVO: again, for some reason, the speed dropped to USB_2.0. By the way, I did not find any difference in read / write speeds between USB_3.0 and USB_3.1.
