Can anyone explain this?

My 240GB WD hard drive (striped RAID X2 WD 120GB) has halved in benchmark performance on Dr Hardware if you look at the date of the last benchmark test (red collumn is current).

What could of caused this? I defragged it last night.

Any help is appreciated,

Ta.

Try another disk benchmark first to make sure it's not just that program (never used -- or heard of -- "Dr. Hardware").

Onboard RAID, or an add-in card? Did you change any drivers? *Something* obviously changed...

Try this .sysanalyser.

Onboard RAID. Not sure if any drivers are changed, though i have installed the latest nVidia stuff and that has RAID manager. Might have changed the original drivers?

Would drivers really reduce the performance that much? And if so, what to do?

Pic of RAID setup. I think i've changed the RAID drivers/setup.

Try System Restore to an earlier date before you made that change.

Hmmm, it seems it may be months ago and system restore only goes back a month. Does anyone know how to restore its raid config and would this be risky?

Does anyone know how to re-setup RAID so i can get my read and write speeds back?

First question. How many drives do you have? My read says one drive - striped in RAID. Why? With 1 drive, unless it is required in order to access a SATA drive, RAID 0 brings nothing to the party.

If it is just one drive - then why not just disable the RAID 0 and access the drive as a single master drive?

I have two striped.

I just want to understand how their performance has gone down drastically that they are level with standard hard drives. Not sure how i disable RAID 0 and would it be risky accesing the drive as a single master?
