LAN Speed Test version 4 (Beta 6) is now available! Click Here for details

LAN Speed Test was designed from the ground up to be a simple but powerful tool for measuring file transfer, hard drive, USB Drive, and Local Area Network (LAN) speeds (wired & wireless). It does this by building a file in memory, then transfers it both ways (without effects of windows file caching) while keeping track of the time, and then does the calculations for you. Simple concept and easy to use. You’ll find that LAN Speed Test will quickly become one of your favorite network tools!
