Just updated to this as I was having some major issues writing - on patching games (eg Planetside 2) it would slow down the whole system and make it in-operable while patching - this seems to have increase the speed again!
edit; did a benchmark - maybe not:
Do you think it could be Diskeeper messing up the speeds? Does anyone use it?
I'm not sure how to fix it, but its a bit slow.
Just a bump from this, reinstalled Windows this morning due to GPU Driver issues.
Anyway, thought my system seemed a bit quicker from the previous issues.
That would explain it Not sure what happened/fixed it, but did a clean Formatted install and it seems ok again!
