[SOLVED] Problem transferring large amounts of data to ntfs drive

Question

I have about 150GB of files that I am trying to transfer from my home partition which is ext3 /dev/sdd2 to another partition which is ntfs mounted with ntfs-3g /dev/sde1 (both drives are internal sata). The files are sizes ranging from 200MB to 4GB. When the files start to move they transfer at a reasonable speed (10 to 60MB/s), but will randomly (usually after about 1 to 5GB transfered) slow down to about 500KB/s transfer speed. The computer becomes unusable at this point, and even if I cancel the transfer the computer will continue to be unusable (I must use alt+sysreq REISUB). I have tried transferring with dolphin, nautilus, and the mv command but they all will produce the same results. I have also tried this in dolphin as root with no change. If I leave dolphin running long enough I also get the message "the process for the file protocol died unexpectedly".
There is nothing that I can tell is wrong with the drives, I've run disk checks on both, and checked the S.M.A.R.T. readings for both disks and everything was fine.
My hardware is an intel X58 motherboard, core i7 processor, 6GB of RAM, 5 internal sata drives and 1 internal sata optical drive.
Another thing to note is that every once in a while I will get an error message at boot saying "Disabling IRQ #19".
This is driving me crazy as I have no idea why this is happening and when I search I can't find any solutions that work.
If anybody knows how to solve this or can help me diagnose the problem please help.
Thank you.

Also I've noticed that if i move / copy things with Dolphin they're substantially slower than if I use cp/mv. But cp/mv works fine for me...
Also run Dolphin from terminal to try and see what's the problem.
Hope that help at least a bit.
Could you explain why Dolphin should be slower? I'm not attacking you, I'm just asking.
Cause I thought that Dolphin is just a „little" wrapper around the cp/mv/cd/ls applications/commands.
