I actualy came accross a setting in my device manager called write cache buffer flushing. When you disable Write Cache Buffer Flushing, this allows application software to blaze ahead after writing data to disk without waiting for the physical write to complete.

I have enabled it rebooted my machine and will post in a few hours how things are going with it.

Now this i won't be a soloution but will deffinetly help write allot more data simultaneously. What should help until i find a SSD/SAS to dedicate my money to.
