![]() That doesn't mean you cannot benefit from using something other than xcopy however. Also the Robocopy option /NP (No Progress) saves you 0 time. This is by no means an exhaustive test, but just throwing a quick real world scenario at some of the more popular tools in this genre shows that your pretty safe sticking with either xcopy or Robocopy (from a performance standpoint only). fastcopy.exe /auto_close G:\folder1 /to=I:\folder2) TeraCopy.exe Copy G:\folder1\ I:\folder2\)įastcopy 60 secs (ex. fastcopy.exe /auto_close G:\folder1 /to=I:\folder2)įiles/directoies: 1,087,180,800 bytes (1.01 GB), 27 files/8 directories copied to external USB disk.

After a couple of passes here are the averages from the tools I played with:įile: 732,909,568 bytes (698 MB), 1 ISO file copied to different directory on the same internal disk. PowerShell was used to capture the start and stop times. No special setup was done (make up your own mind if that invalidates/validates the test), only to input the command into a batch file to execute. All copies were performed between a internal 7200 RPM Sata II disk and an external USB 2.0 drive or on the same internal drive itself where indicated. I ran through a couple of tests on a Windows Vista 64-bit SP2 box to do some comparisons. Essentially, you can consider single large files and multiple smaller files to be two separate types of copy operations depending on your hardware.From a performance standpoint only, xcopy or robocopy will give you similar results. The same thing applies when considering multiple-file operations. Copying a single large file can be a simple matter or a complicated one, depending on whether the file is in contiguous area or split up and written in the gaps on a fairly full drive. The numbers were all over the place, so lets take a look at why they might be the way they are.įirst and foremost, since we are using mechanical drives and not solid-state storage, seek times and the like come into effect. Your mileage may vary, of course, as there are quite a few variables at play here. Our test wasn’t anywhere near scientific, but we did our best to make sure we could rule out interference while still trying to emulate some real-world use. On the other hand, when copying a large amount of smaller files, TeraCopy seems to have the edge. It seems that copying large individual files works best using Windows 7’s copying ability, at least if speed is what counts. I did my best for you readers, and ultimately it came down to the copying programs themselves. This minimized the influence of pre-caching before hitting the Start button on each. I've tried using FastCopy to copy data from shared folder on Synology NAS RS-812+ to my my hard disk with 'ACL' checked but it seems. I also configured TeraCopy and SuperCopier to be the default copiers, and I clocked from the time I hit Ctrl+V. A clean reboot ensured near-optimal performance for each task. Copying the files in order the same way each time discounted any advantage one program would have had over another by way of caching. External A was a 2 TB internal drive in an enclosure, and external C was a 750 GB store-bought drive. All of the drives I ran this test on were 7200 RPM hard drives and had a cache of 8 MB. Why did I decide to do that? Well, there are quite a few factors to this test, including hard drive speeds. Within this type of infrastructure, administrators can make more detailed and precise access permission configurations. The 24 GB folder was a portion of my music collection, mostly. Windows ACL is the 13 different types of file permissions designed by Microsoft for NTFS file systems which can be applied to specific users and groups. The 4.4GB file I used was my Wii disc backup of Donkey Kong Country Returns. The external drives were ejected and the system was rebooted between testing each program. This was done in order for each of the copying methods. And lastly, copied that folder from my internal drive to external C. Then, I copied a 24 GB folder (3300 files, with an average size of about 8 MB) from external A to my internal drive, B. FastCopy will start copying files along with their ACL privilege settings from the Windows server to the shared folder on your Synology NAS. Then, I copied that file to another external hard drive, C. First, I copied a file of 4.4 GB from one external hard drive, A, to my internal one, B. In order to test fairly, I ran four distinct copy actions with each program and with the default Windows 7 copy function.
