2 Samsung 840 Pros RAID 0 w/ EXTREMELY low write speed but normal read....

I've had these SSD's for about 6 months now. When I first installed them I was getting perfect readings. With the Write speed about 900 MB/s or so. I have done NOTHING to the SSD's since then. This is what my write speed is now.





My specs:

Windows 7
Asus Maximus IV Extreme-Z
i7 2600k
GTX 680's SLI
2x Samsung 840 Pro's in Raid 0

In case it is asked, the SSD's are correctly installed in the proper Intel ports on the motherboard.

What could be causing this? I have no idea :(

  1. Do you have write back cache enabled in the IRST control panel?
  2. Redeemer, I don't think I do. How do I go about enabling that?


    EDIT: I'm in the IRST control panel and it is enabled. Is that good?
  3. Downloading that driver now.

    as SSDs get full they slow down. clean it out and see what happens.
