Question about SATA ports on GigaByte GA-Z68A-D3H-B3. NEED HELP!!

Ok so right off the bat, I apologize for my noobishness. I may have a pretty sweet rig but my knowledge of computer hardware is still super limited. So im putting together an xmas list and wanted to put some additional internal hard drives for my rig on my list but Im not sure how many SATA II and SATA III ports my motherboard has. My motherboard is a GigaByte GA-Z68A-D3H-B3 [...] d=3910#ov. It says in the Storage Interface section.


2 x SATA 6Gb/s connectors (SATA3_0, SATA3_1) supporting up to 2 SATA 6Gb/s devices
4 x SATA 3Gb/s connectors (SATA2_2~SATA2_5) supporting up to 4 SATA 3Gb/s devices
Support for RAID 0, RAID 1, RAID 5, and RAID 10
* When a RAID set is built across the SATA 6Gb/s and SATA 3Gb/s channels, the system performance of the RAID set may vary depending on the devices being connected.

2 x Marvell 88SE9172 chips:

2 x SATA 6Gb/s connectors (GSATA3_6, GSATA3_7) supporting up to 2 SATA 6Gb/s devices
2 x eSATA 6Gb/s connectors (including 1 eSATA/USB Combo connector) on the back panel supporting up to 2 SATA 6Gb/s devices
Support for RAID 0 and RAID 1

So does this mean that my motherboard has internal support for up to 2 SATA III's and 4 SATA II's or 4 SATA III's and 4 SATA II's?

Im just trying to figure out what my hard drive distribution needs to be like. I realize that my case only has slots for up to 6 HDD in the front HDD cage so im only really looking to have a total of 6 drives because I don't see that there would be space on the interior for any others. Anyways I just want to figure out how many different drives of each type my current set can support so I can figure out which drives to get.

Is there such thing as a SATA III to SATA II adapter cable?

Thank you in advance for your help. I hope to get some assistance on this soon so my mom can might be able to do some black Friday shopping like she wants.

  3. Ok so I did a little research and confirmed through MaximumPCS testing that there is literally no difference whatsoever between SATA 1, 2, and 3 cables, so now what I'm wondering is if plugging a SATA III drive into a SATA II port would still function correctly? I mean I would assume that since the cords themselves are identical that it would work, likely reducing the transfer rate to 3.0 gbps as is the standard for SATA II since if there is no difference in transfer rate of the cords it must be the plugs themselves that make the difference. Anyways I'm just curious if it would work because for some reason SATA III 3tb drvies are cheaper then SATA II 3tb drives so even if the transfer rate would only be 3.0gbps it would still be cheaper.

  5. They are fully backwards compatible 6GB drive works fine on 3GB port. Normal Mechanical HDD even 6GB one can not even max out the 3GB interface.
