drastic speed differences on copying on hard disks

lsu420luv · 04-16-2006, 12:59 AM

I have two SATA 150 hard disks. When I copy large files from one of them at mount point Doanloads to the other at mount point Storage it is only like 8 MB/s When I copy from other folders in this drive to the other drive it goes up to almost 75 MB/s Is there a reason for this? IS it suppose to go up that high? If so why doesnt it always go up this high. The conditions are identical except for the directory it is in. Thanks

So you're saying that the copy performance is extremely poor only when you copy from a particular folder? That sounds weird. Is there anything special about that folder, like ownership, permissions, etc?

I dont think so. The Storage folder and the Downloads folder should be exactly the same. It actually just copied one from Downloads to Storage at 76 MB. It usually is like 7.6 It is very strange. Permissions could be causing the strange behavior?
The two folders are both seperate partitions, but set up exactly the same except the mount point
