not sure if this would help me, as i have the ahci version of the drive. i'll have to do some more research. but thanks for the link.
Hi all, first post here it’s an amazing Forum with great participants and a very informative one.
You can try the latest IRST 13.6.0.1002 driver, or an old one, the IRST 13.2.4.1000, used by Anandtech’s review of this drive: http://www.anandtech.com/show/8979/s...12-gb-review/2
Both drivers (available in Intel Download Center) should give SM 951 much better performance than native Microsoft drivers, as it’s usual with almost all AHCI drives, after all the AHCI technical standard was developed by Intel.
Just my two cents...
Cheers
SATA (AHCI) will not be a dead end for quite a while. SATA disks will continue to be more cost effective than flash or phase change storage, which is what NVMe is for. You cant plug a SATA or SAS hard disk drive into NVMe. Saying AHCI is dead because of NVMe is better is silly as they are apples to oranges.
Now SAS may replace SATA, but SAS drives are generally more expensive than SATA. SATA drives are compatible with SAS, but that requires the SATA protocol gets tunneled through SAS (STP), and the drive still appears as SATA/AHCI to the OS.
I can confirm that this problem exists in Windows 10. I have an Asus X99 Deluxe mobo with the SM951 AHCI. Under Windows 7 i was able to get 2200MB/s read. Now i am not able to get over 1550MB/s. I have tried the ssd in the M2 slot and on the hyper-card. Makes no difference. Installed IRST_V14_5_0_1081_WHQL. Makes also no difference.
