Very Low Write Speeds Samsung 128GB 840 Pro

post #1 of 5
Thread Starter 
After searching online for hours now I have given up. As you can see in the pics the write speeds are super low. This drive is less than a year old with 80+gb free. I have used Seans guide and did exactly as stated. The drive is connected to the sata 6Gb/s (sata 3) with AHCI on. Trim in enabled and checked. Tried using Samsung's Magician OS Optimization and the difference between there's and Seans was the page file size and hibernation being on which ate up another 30+gb so I went back to what I had. There was no difference in speeds. I am running on the older firmware only because of what I have read from people after updating and to be honest I don't think it would make that much of a difference and it's suppose to help with read speeds in which mine are fine. I disabled C1E in the bios to see if that did anything, nothing. My system specs are below . I don't know what to do, any suggestions.

Go to Control Panel,Device manager,Disc drives and then right mouse click for properties of SSD drive.There you will see "Policies",click on that and then enable "Enable write cache on the device"

Do this ^

& also check the Turn off windows write-cache buffer.

Make sure both boxes are checked & try again.

Thank the lord, thanks a million guys. Something so simple as not having one box checked. It was the "Turn off windows write-cache buffer" as I already had the first one checked. Reps to the both of you.
Thank You

No problem.. I had the same issue when I did my reformat. For some reason with X79's (Maybe not all) it doesn't check that 2nd box.
