Do You Actually Need a Driver? (Important Distinction) Before downloading anything, understand this:

Windows 10 & 11 (up-to-date): No additional driver is required for basic operation. Microsoft includes a generic USB Mass Storage driver (USBSTOR.SYS) that works. However, without the specific Realtek driver, you may lose UASP (USB Attached SCSI Protocol), which reduces speed and TRIM support. macOS: Typically works out of the box, but using an older OS may require a kernel extension (kext). Linux: Built-in NVMe and USB storage drivers work seamlessly. Older Windows (7/8/8.1): You must download and install the official driver.

Bottom line: For best performance, especially UASP and proper ejection, you should download the official Realtek driver even on Windows 11. The RTL9210B-CG is a highly popular, high-performance USB
