Hello and Merry Christmas!

I managed to figure out some info but I still have no clue about all this.

I installed Windows 10 on an SSD with old mobo MSI P55A Fuzion that has 6 Sata 2 and 2 Sata 3 on Marvell controller. (The Marvell is reported, even by MSI forums, that it is does not exceed 3Gb/s).

I still wanted to test the Marvell controller in case it was working as advertised on box (6 Gb/s)

In main Bios > Integrated Peripherals > SATA 6Gb/s Controller Mode I changed it from IDE to AHCI (Options are IDE/AHCI/ and maybe Disabled not sure)
also in same page On-Chip ATA Devices > RAID mode I changed IDE to AHCI (Options are RAID/IDE/AHCI)

After installing windows, In boot I see the Disk described as 5Gb/s but Marvell Bios it says:

Marvell Info:

PCIe speed rate: 2.5 Gbps
Configure SATA as: AHCI mode

Disk Info:
Type: SATA PD
Feature support: NCQ 6GB 48bits
Current Speed: 6G

In Windows SSD appear as SCSI

in Main Bios (not Marvell) SSD appeared somewhere as IDE I think

Crystal Disk 7 results:



I have many questions, please answer whatever you can :sweatsmile:

1.What do you think of benchmark?

2. Is it normal that SSD show as SCSI instead of AHCI in windows?

3. If I want to test Intel controller instead of Marvell:
A. Do I have to reinstall windows?
B. What settings I have to change in Bios?

4. What is the relation between "SATA 6Gb/s Controller Mode" setting and "RAID mode" setting under "On-Chip ATA devices", I mean the 6Gb/s is only found in the On-Chip? I mean the first settings imply talking about Marvell, right? what is the difference between these two? when should I use each of them?

Regards!

2. No.

3.A. No
3.B. None

4. RAID mode would refer to being able to setup a RAID array controlled by the motherboard.
In the case of this particular motherboard, Marvell is technically SATA III, but actually slower.
The built in chipset SATA controller is SATA II.
