Slow NAS file transfers on Windows 11 often trace back to local network and protocol issues rather than internet bandwidth, since an online speed test measures only the connection to your ISP, not the path to your storage box. This tag gathers discussion of diagnosing SMB performance, using Robocopy for large folder copies, and identifying 2.5GbE bottlenecks that can drag Windows File Explorer transfers down to a crawl. It suits readers troubleshooting sluggish copies between a Windows PC and a Network Attached Storage device who want practical ways to isolate whether the limit sits in the link, the protocol, or the drive itself.
