I go into the BIOS the storage device config list Hard Disk under SATA3 and the CD/DVD drive is listed under SATA2.
Under Storage Options the removable media boot is set to enable and the SATA Mode is set to RAID+AHCI.
I am stumped as to why i am getting such slow speeds, i did try other bechmark tools and they all listed the same speeds.
My BIOS Version is 3.91 if that makes a difference.
I am also on 3.91 bios, and before upgrading to the Samsung 950 Pro NVMe drive I had a 850 EVO Sata drive - this was performing at full speed. It is not a driver issue, since the Sata drives just use the standard Windows 10 drivers.
I would go for a full clean install of Win 10 in UEFI mode and see if that clears up the AHCI issue. The other thing you can check is the Sata cable - a bit of a long shot, but maybe try changing it for a new one where it explicitly states it supports SATA3?
Dude.......you have NVMe, i'm pretty jealous not gunna lie. But yeah this is actually a completely fresh new clean install of Windows 10 Pro using UEFI. I've reinstalled it numerous times trying to figure out why it will not function at it's normal speeds.
The cable i'm using is a SATA 6GB/s StarTech cable, which may be the issue (StarTech is junk most of the time), i'll swap it out when i get some time today.
And the drivers are actually not the generic windows drivers they are the offical Intel RSTe driver for SATA RAID is what got the drive to show and finally work this last time around.
I'll post an update here soon after i swap this junky cable out and retest.
I also have low hopes since HP's always have issues with our setups for some reason.
