F@32

I had a shot at the 9260 on my Asus CHIV, it didn't work as my boot drive was configured for RAID and and as soon as I installed the 9260 it just wouldn't let me select my boot drive again.
All that was left was the 9260 and I can't reconfigure the drives right now.

Will give it a go at some later point in time.

The performance you saw might just be a result of mixing drives, sometimes it works OK but not all of the time.
After all the X25 and the SF are different beasts.
