I tried in vain to look for a solution, to give you an example: Iíve got a RAID5 array with 3 x 1TB hard drives and a lone Raptor 150GB for the OS. If I played back a 1080p trailer off Appleís site stored to my hard drive using Quicktime Alternative the video would start to skip massively if at the same time I copied a large file from the RAID5 array to my Raptor disk, or extracted a file using WinRAR in the same manner.
Of course this is not the only problem, just an easy way to reproduce it. When I extracted large files I noticed that the Task Manager did not report memory being used under its graph, however the counter for available memory under ĎPhysical Memoryí would go down a whole lot, using as much as 4GB of RAM when copying files at least that large!
