I was looking for ways to boost the speed at which files copy from drive to drive. In my search, I found an excellent free option called TeraCopy. It has a very nice feature list and a pro-version of TeraCopy can be tested for 30 days before committing to 14.95 (in euro, about 2o usd).
- Copy files faster. TeraCopy uses dynamically adjusted buffers to reduce seek times. Asynchronous copy speeds up file transfer between two physical hard drives.
- Pause and resume file transfers. Pause copy process at any time to free up system resources and continue with a single click.
- Error recovery. In case of copy error, TeraCopy will try several times and in the worse case just skips the file, not terminating the entire transfer.
- Interactive file list. TeraCopy shows failed file transfers and lets you fix the problem and recopy only problem files.
- Shell integration. TeraCopy can completely replace Explorer copy and move functions, allowing you work with files as usual.
- Full Unicode support.
To find out if I really was getting any speed boost though, I decided to do some tests with TeraCopy and Windows Explorer Copy. I’ve always known that copy on Windows Vista was to say the least, slow.
My tests were pretty simple, nothing scientific here either. The results aren’t comprehensive enough to merit a definitive answer. I think you should try TeraCopy regardless. TC means TeraCopy and WC means Windows Copy, times are in minutes:seconds format.
My first test was moving a Fedora 10 ISO, about 3.89 GB, from one drive letter to another drive letter on a physical drive. In this test, my average time for TC was 2:36 while for WC, the time was 3:12. TC was 24% faster on average than WC.
The second test was moving the same Fedora ISO but it was being copied to a different physical drive. The average time for TC was 1:17 while for WC it was 1:23. Tiny difference being 5%.
The third test was moving 1.5GB of music files from one drive letter to a different drive letter on the same physical drive. The average time for TC was 1:05 and for WC the time was 1:11. Not much of a difference here, only 6% at most.
Finally the final test was moving the same music files to a different physical drive. This took TC only 36 seconds while it took WC 46 seconds. That’s a small difference, only 15%.
So in the end, it appear that TeraCopy is just slightly faster, maybe just 12% faster than Windows Copy. Is that enough to keep it around? I think so.
