Gigabyte GA-X99-Gaming 5 SATA connectors doubt

[Black_I_C_E]

The Gigabyte GA-X99-Gaming 5 has two sets of SATA connectors, SATA3 0~5 and sSATA3 0~3. Which should I use? I plan on a SSD (o.s.), a SSHD and a DVD. Is there any difference, apart from RAID support?

Thanks.

"With regards to the SATA port situation, Intel is enabling ten SATA ports total but only six of them for RAID. While this is an update over X79, it seems more of a fudge. One would assume that it could be a bandwidth issue, because the link between the CPU and chipset (PCH) is at 20 Gbit/s, or 2.5 GBps which would be saturated by a 5-6 disk RAID-0 array. However, it seems silly to not have RAID on four of those ports. Due to Intel’s previous flex-IO arrangement on Z97, this seems more of an integrated SATA 6 Gbps hub, splitting the bandwidth into four ports. Due to the hub it would limit throughput in RAID so it makes sense to disable it completely for those ports. Intel is telling us that this is due to two separate AHCI controllers in the chipset, with only one of the AHCI controllers enabled for RAID.
For motherboard manufacturers, this gives several options. If the chipset is using Flex-IO which we believe it is (we are still awaiting confirmation), then the amount of SATA 6 Gbps/USB 3.0/PCIe 2.0 lanes is slightly flexible similar to Z97. By providing 10 possible SATA 6 Gbps ports (6+4 of RAID/non-RAID), the motherboard manufacturer could implement a 4+4 arrangement to give more PCIe lanes, or shift around the PCIe lanes in that 4+4 to give a full six USB 3.0 ports. The truth of the matter is that there are very few users who require a six-drive RAID, and so motherboard manufacturers can target different orientations of motherboards for different user segments. The non-RAID possible ports are still fine for optical storage or hard drives with a software RAID-1 applied over the top."

So. Apart from RAID and bandwidth sharing, no difference.
I'd use the SATA3 0~5 for drives, with SSD connected to port 0.
