Manufacturer description

The SSK Portable SSD 500GB is built for fast transfers and on-the-go video capture. It runs over USB 3.2 Gen2x2 at 20Gbps and reaches read and write speeds of up to 2000MB/s, so large photo libraries and 4K footage move in seconds instead of minutes. The external SSD uses 3D NAND with an SLC cache. It sets aside 25% of the available capacity as a high-speed buffer to hold burst transfers at full 20Gbps speed. S.M.A.R.T. monitoring lets you check drive health, and TRIM support keeps write speeds steady over time. Two cables come in the box: a 20Gbps USB-C cable for Gen2x2 hosts and a 10Gbps…

Why does Windows show only 465GB instead of 500GB?
