I'm trying to determine what is the maximum supported SATA version on my laptop. My laptop has: one mSATA SSD, one HD, one Optical Drive.
Using HwInfo, I see:
- Bus\Intel Panther Point-M PCH - SATA AHCI Controller: [SATA Host Controller] Interface Speed Supported: Gen3 6.0 Gbps
So It seems that I have a SATA III controller; but then:
[SATA Port#0] (this should be the HD) Port Status: Device Present, Phy communication established Current Interface Speed: Gen2 3.0 Gbps [SATA Port#1] (this should be the SSD) Port Status: Device Present, Phy communication established Current Interface Speed: Gen3 6.0 Gbps [SATA Port#2] (this should be the Optical Drive) Port Status: Device Present, Phy communication established Current Interface Speed: Gen1 1.5 Gbps
So it seems that the HD has a SATA II. In fact under drives the HD shows as:
[General Information] Drive Controller: Serial ATA 3Gb/s @ 3Gb/s Drive Model: WDC WD10JPVT-75A1YT0 Drive Capacity: 953,869 MBytes (1000 GB) Drive Capacity [MB]: 953869 Media Rotation Rate: 5400 RPM ATA Major Version Supported: ATA/ATAPI-5, ATA/ATAPI-6, ATA/ATAPI-7, ATA8-ACS ATA Transport Version Supported: SATA 3.0
So what's the truth? My best guess is that the laptop has a unique SATA III controller, and the SSD is SATA III so maximum speed, the HD is SATA II so lower speed, the Optical Drive is SATA I so lowest speed.
If I replace the HD with a new SATA III SSD, will it perform as at SATA III or SATA II speed?
