Slow Write Speed Asus M4A89GTD SB850 Force 3 120

Wondering if anyone has any ideas how I can get the write speed up to par.

 

My reads are generally good above 400 in any config.

 

My writes never break 100... usually sit around 98-99.

 

What I have tried so far:

 

updated cables to the 6GB cables included with my motherboard.

 

tried disabling USB3

 

tried disabling C1E

 

tried using the default windows 7 AHCI drivers

 

tried using the amd catalyst AHCI drivers (1.2.0.164)

 

the motherboard is a Asus M4A89GTD PRO/USB3 which has a SB850 Chipset

running 6 xSATA 6.0 Gb/s ports

 

the SSD is a corsair force series 3 120GB (firmware 1.3.3)

 

Windows 7 pro 64bit was installed in AHCI mode cleanly onto the force3.

 

Anyone have any ideas?

 

Thanks for your time

 

 

EDIT: well... after browsing around on the forum here I noticed the suggestion to try ATTO, I had been using passmark's performance test 7.0 (since I use their data often to find the fastest drives on sale ;) ) and the ATTO shows me hitting some high write speeds... while the passmark always shows the write stuck at 98-100.

 

They claim the test is a "sequential write"... running an ATTO shows smaller files sizes slower but the write's really kick into gear at the 8KB filesize.

 

So I guess I am not really having an issue at all with the drive, but instead with the test.

 

Any suggestions as to what ATTO config I should try to verify it is indeed working at peak performance?

Just posting since I have now done a compare of the two drivers in hopes this worthless thread is of use to someone in the future :)
