I just moved one 7gig folder from one drive to another on the same machine and it took 12 minutes! Is that normal? I also backed up the same file to and external USB drive and it took 23 minutes! Again, is this normal? Thank you very much for you comments. Did the folder contain just a few very large files, or many smaller ones.
For each file, there's some overhead time for setup of the operation. Size of drive buffers will have an effect as well. And, if you can arrange it, having the drives on diffent controller channels will improve efficiency.
The USB dirve time sounds much worse. Theoretically, USB 2. Even allowing a bit more for file copy overhead, that is still way too slow. I don't have any suggestions for that problem.
Thanks Val, I am not really worried about the internal drives because that was a one time thing, but I am a little concerned about the USB drive! Hopefully someone here can help me out.

Patrick Keenan said:. Those times aren't really out of line. Yes, large files can take time to copy. If you reduce the number of other processes running, you can make sure that the system devotes as much attention as it can to the task, but there are bottlenecks, such as the speed of USB.
Depends on the speed of the drive, how fragmented it might be, size of the files Around an hour, maybe more. Transfer rate for USB2. Join Date Jun Posts 1, Originally Posted by eolesen.

Using the formula, it should have taken 29 seconds, so your mileage can and will vary depending on the condition and speed of the drive.

Thank U everybody Alabalcho Titan. Jan 13, 13, 75, 3, Are you copying many small files, or a few large ones? I'm copying thousands of small files twice a week. I need to do this in archival purposes, as a part of a big data base of clients. All amount is about 70Gb of info. Need to speed up. In them days I Used Blu Ray rewritable disc in archival purposes and it seems to me it took me less time to burn a disc previously erased , then now throw almost the same amount of info from one HDD to another But 2 hours is killing me Mar 16, , 9, , 22, From an internal drive to a USB drive?
Yes, that WILL take a long time. The only magic is better hardware. Reactions: Garry Make it do this copy from 1AM to 3AM The problem is that I need to do it during daytime and concerning better hardware you mentioned in a link, I tried to use something like this to obtain usb 3. I think such card is not an option for my type of mobo. Nov 3, 13 2 15 0. Garry said:.

With both fast source and destination media, your times should be trimmed considerably A Also, someone more knowledgeable, is it too much of a hassle to use raid 1 or somesuch with 3 HDD's?
Raid 1 keeps two identical copies I recall. So at backup-day, take one HDD from work to home new backup copy , next morning you're in trouble at work: comes when you bring ex-backup HDD from home to be overwritten. On plus side the data is always in two places.
Disclaimer: not a clue about raid B Repeat: please do check rar or some other program that does one file but doesn't compress your backup data , I'd like to hear if it's faster - I bet it will be, since you won't be creating complex file structures to the backup-copy, just few files.
So maybe don't need to copy whole 70Gb, but only files that have changed meanwhile? Didn't really time, but was rather fast. Also, if you can keep that backup70Gb.
Used: winrar with no compression, hardware has dual-channel 2x4Gb memory, software encrypted 1Tb drive, usb3. Windows 7 in bit faster drive not encrypted alone none SSD's, well, usb drive but meh. Just bought a "slow" ssd so moving to win
