Question How can I connect two other extra 6 GB/s data-transfer-rate supported internal HDDs to my motherboard which has only 2 SATA ports that supports 6 GBPS

My motherboard is Intel DZ68PL and has only 2 on-board SATA ports that support 6GBPS data transfer rate, but I wanna connect 4 internal HDDs that support 6 GB/s data transfer rate together (All 4 HDDs at the same time). Is there any way to do this?

Sata 6gbps is generally meant for SSDs.
For HDDs - SATA 3gbps is plenty. In fact - HDD can not saturate SATA 3gbps bandwidth.
So it doesn't really matter, if you connect a HDD to SATA 3gbps or SATA 6gbps.

If you wanted to connect more than 2 SSDs to your pc, then solution would be PCIE SATA 6gbps controller card.
Something like this:

I think this cable will do the trick if I want to connect internal HDD via USB 3.0 port! - https://www.amazon.in/Matefield-2-5Inch-3-5Inch-Drive-Adapter/dp/B07KPB8JJK?tag=googinhydr18418-21&tag=googinkenshoo-21&ascsubtag=_k_EAIaIQobChMI19bt68nH4QIV3AQqCh1PYwZcEAQYAyABEgIzK_D_BwE_k_&gclid=EAIaIQobChMI19bt68nH4QIV3AQqCh1PYwZcEAQYAyABEgIzK_D_BwE But, I wonder if this way will be nearer compared to SATA 6GBPS cable or not in performance, as USB 3.0's max speed is 5gbps! But, hopefully faster than 3GBPS SATA ports!

As you've already been told, it doesn't make a difference. You're limited by the relatively slow speed of hard disk drives. It's not going to be any faster, you're just wasting USB slots.

You could build a time machine, travel to the future, and bring back a cable that allows you to transfer data at a terabyte per second and your hard drive still won't be any faster.

USB is for connecting external drives. It's temporary connection - connect drive, copy over some files, disconnect the drive. You don't use USB for permanent HDD connection.

Use sata to connect internal drives. As told before - for connecting HDD 3gbps and 6gbps connection will be equally fast. 3gbps connection tops out at ~260MB/s. Top transfer speeds for fastest modern HDDs is ~200MB/s.

----------------------------
1.7 SATA Interfaces

The board provides six SATA connectors through the PCH, which support one device per connector:
•Two internal SATA 6.0 Gb/s connectors (blue)
•Two internal SATA 3.0 Gb/s connectors (black)

•One internal eSATA 3.0 Gb/s connector (red)
•One eSATA 3.0 Gb/s connector on the back panel for external connectivity (red)
-----------------------------

Use the two blue and the two black SATA ports. That is what they are for. Hard drives have not gotten magically faster, and the 2x SATA II (3.0Gb/s) will run them at top speed.

Salmon Trout - https://www.computerhope.com/forum/index.php?action=profile;u=71192 - suggested using a SATA III 4 Port PCI-e x1 Controller Card - I think this is the best bet!
Nonsense. A spinning HDD will not saturate a SATA II (3.0Gb/s_ connection.

You are chasing performance that cannot happen.

You have an old car (HDD) with a known top speed of 90mph. If you put that car on a race track, it will still never go faster than 90mph.
Other vehicles (SSD, NVMe) will go 150 or 200mph on that track. But your car will never ever go faster than 90mph.
