Best Intel RST driver for Maximus V Gene Z77?

Level 9
Hi all,

Just replaced a tired Samsung 840 Pro SSD, with a new 860 Pro SSD. The IOPS were low on the 840, I figured mostly because the drive is 5+ years old, and has 160TB written. But after installing the 860 Pro, the IOPS are indeed better, but not to their full potential I suspect. I have yet another 840 Pro in my wifes Windows 7 system, that consistently maxes out IOPS at 90K read and about 80K write. So I don't know if this is a Windows 10 issue or not. I have verified both SSD's are plugged into the Intel controlled SATA 6Gbps ports. Both setup for optimum performance, with 10% over-provisioning. Seems ASUS has forgotten us Z77 users, they released some Beta Windows 10 drivers, but that's all. I kind of suspect the Intel rapid storage technology driver, as I had an Intel rep on the phone suggest a different driver version ( than what ASUS has listed on the mobo's download page, and throughput did go up a little. Sorry for the rambling. Appreciate any insight a fellow Maximus V Gene user running Windows 10 might have, thank you.
