Flashing to the new F6 bios cuts SSD drive write speeds in half. This is a known issue as ive seen it mentioned elsewhere on the internet. If Giga employees don't read this please someone relay it to them.I've already mailed them myself. Only flashing back to F5 fixes the issue.
I'm not 100% certain this applies only to OCZ Series 3 drives or to all SSD's.Here are pics of F5 then F6 drive tests. Notice the write speed on the F6 bios run.
