Obviously this can’t hold up forever, but Windows can use up all remaining free memory as a temporary buffer to store most, if not all of the the file that is being read in memory. So instead of waiting for the previous chunk to finish getting written, and then reading the next chunk, a new chunk can be read while the previous one is still being written. With this transfer algorithm, each byte of the file is gets processed only two times: one read, one write.īut in addition, Windows uses memory (as does the drive itself) to cache some data. Write the chunk to the destination drive.Read a chunk of data from the source drive into memory.This is the general procedure for copying a file with Windows Explorer: Two words: verification and cache Technical Explanation Over gigabit connection, Teracopy does 31MB/s, but Windows 8 does it at ~109MB per second? What exactly is causing this? And can I enable such speeds via Teracopy? I really dig the extra features that Teracopy has, will surely miss them now :D I then stumbled upon this little piece of info after which I turned off Teracopy and copied the same file through Windows 8's regular copier.
So just for the sake of doing it, I iPerf'd both the systems and guess what that showed - around 875mbps on both systems!
Although satisfied with the 30-34 MB/s that Teracopy was showing (that was a proper step-up for me from 10 MB/s), I still was curious about this massive difference in the advertised and real-world speed.Ģ hours of Google had me believing that there were other factors that resulted in less speed, SMB being one. TeraCopy is free for non-commercial use only.I got my brain-melting first taste of Gigabit networking today, between my 2011 MacMini and Windows 8 Pro desktop connected via Cat.5e to Linksys WRT320N(sporting dd-WRT).Īfter making sure that the line speed on both systems showed 1Gbps, I proceeded to copying a 2.4GB MP4 from the Mini to the Win 8 desktop (SMB sharing). Note: Advanced file list management functions are not available. If you want to speed up your copying or if you regularly transfer large amounts of data and have to stop the process to perform some other disk-intensive task, this program may be just what you need.
One of the most common complaints about newer versions of Windows is the slow copying speed, especially when transferring lots of files over the network. TeraCopy is a free utility designed to copy/move files faster and more secure. TeraCopy 2.3 Download for Windows 10, 8, 7
