You misunderstood, sorry about that, my bad. I meant under 'install it in the DVD drive' slot' that I plug out the DVD driver from the MB's 2nd SATA slot and put it into the 3rd slot . Then I plug the new HDD into the second SATA slot where the DVD driver was. So the final result would be:
From:
SATA slot 1( yellow SATA6G): 1st HDD
SATA slot 2( yellow SATA6G): DVD driver
To:
SATA slot 1( yellow SATA6G): 1st HDD
SATA slot 2( yellow SATA6G): 2nd HDD
SATA slot 3( dark brown SATA3G): DVD driver
So I assume I need to arrange the letters in disk management, right?
It makes some difference.
6gb refers to the transfer rate from the device buffer to the motherboard.
Hard drive performance is primarily determined by the mechanical performance of the HDD.
But most new HDD devices will have the ability to transfer data to/from the cache at 6gb.
I would simply move the dvd connection to sata 3, and plug in the hdd into sata 2.
It should not matter what drive leters you get from this procedure.
If it does, you can rename then in windows.
I might add that today, with SSD prices getting better, I would look to using a SSD, particularly for windows.
A 6gb connection for a ssd is definitely faster since there is no mechanical delay.
Instead of adding a second HDD, why not buy a 1tb Samsung 870 QVO to replace your C drive?
It will cost about $100. If one tb can cover the used portion of your C drive and then some,
Use the samsung ssd migration app to move your C drive to the ssd.
Here is a link to the app and instructions:
Download various software related to your product, including Samsung Magician, designed for use with Samsung's memory products, and find related information.

Believe me, a ssd will be the best performance upgrade you can make.
