Hi all

This is a bit of an ongoing discussion on the Crucial forums, but thought if anyone could spare the time to read through and see what you think is going on.

To summarise, I've only had the drive 2 days. The drive used to be the same speed give or take to safe mode when I first installed Windows to the drive, but after some time installing Windows updates and a few applications the drive performance has dropped up to around 40% write-wise and some degration in read times.

I am running the drive on a Asus P7P55D.

Basically, I had updated to the latest Intel Rapid Storage drivers and used other drivers on the Asus website, and installed some applications and the drive was running fine - but has suddenly dropped in performance, as far as I know, without touching any more drivers related to the drive while I continued to install more apps. I'm fairly sure it's driver related if it's fine in Safe Mode?

I say it could be driver related, because in that thread I was asked whether any apps were open that could affect the drive (no), whether defrag scheduler is disabled(yes), whether it is in AHCI mode(yes). Nothing seems to point to what's going on. I even let the drive sit idle on the logoff screen all night so it could GC, with minimal improvement.

I realise this isn't going to affect me considerably in the real world, but it's just baffling why it is quite a bit slower than it is in safe mode and from when I first installed Windows with the recommended drivers.

Any ideas?
