check the snips i'm adding as well. looks to me like all drives are running in IDE. i don't know what AHCI is or why its better for an SSD. would that help speed up my SSD?
Sata 3 GB/s or Sata II would slow it down some as the m4 is a Sata 3 device.
AHCI or Advanced Host Controller Interface adds a few features like Native command queuing (optimizes read/write which gives a little more performance, less wear on the drive - but it's not really a 'night vs day' performance increase. It also allows for hot swapping (unplugging the drive while the PC is on. Not much use if you don't swap drives much
Bottom line, it would improve performance a little. How much you'd notice is questionable.
But between it being IDE and on a Sata II controller, that's why your score is lower than others.

How do you determine whether the setting should be IDE or AHCI under these "mixed" circumstances?
If you installed the OS while in IDE mode, changing it to AHCI would indeed cause boot failures. You have to 'prep' the system first before changing the BIOS setting. Basically you have to change a few settings in the registry and then change the BIOS.
Are any of your devices IDE? ie Connected with the old flat ribbon cable? If so, you wont be able to switch over to AHCI because those devices need IDE to be seen. Your Optical drive for example.
But since it looks like all your devices are sata 2 at minimum, where did you notice the missing devices if you couldn't boot into the OS?
