Review on Vansuny 128GB Metal Waterproof USB 3.0 Flash Drive - Ultra High Speed Memory Stick for PC, Tablets, Mac, Laptop - Portable Thumb Drive by Sabrina Guarino

The Vansuny 128GB is a high-speed USB 3.0 flash drive that works out of the box with Windows and MacOS. a glass of water to ensure the "waterproof" claims are correct and it still works the same as before. As I have seen many complaints that storage media does not have the capacity specified by the media capacity as specified by the manufacturers and the Windows operating system. Media manufacturers measure capacity in decimals (1GB = 1000MB / 128GB = 128,000MB). The Windows operating system uses a binary system to measure disk space (1 GB = 1024 MB / 128 GB = 117,000 MB). For this reason, your flash drive, hard disk or SD card may have less capacity than manufacturers specify . In this case, manufacturers and operating systems such as MacOS and Linux use the correct measure (giga prefix = 1000). When I receive USB sticks or SD cards, I fill them up to 98-99.5% of their capacity with data and read the files to make sure they aren't fake and that my data is safe. This means that 128 GB of capacity is available, or 117 GB under Windows. The Vansuny 128GB flash drive is described as "read speed up to 70Mbps, write speed up to 20Mbps", but it was able to achieve a read speed of 159MB/s and a write speed of 143MB/s. It took 33 minutes: 40 seconds to fill a USB drive with large 117GB video files at an average write speed of 57.92MB/s. This speed doubles when writing smaller files. The Vansuny 128GB Flash Drive is stylish, affordable and delivers USB 3.0 speeds.
