ROG Z890 Maximus Hero, question about SlimSAS port and additional Sata drives.

[JBBlack]

Hello all, I have a quick question about using the SlimSAS port with a  𝐒𝐥𝐢𝐦𝐒𝐀𝐒 4X to 4*SATA，𝐒𝐅𝐅-𝟖𝟔𝟓𝟒 38pin to 4x𝐒𝐀𝐓𝐀(7pin) Cable, 100CM cable connector.

 I have never used SlimSAS before, so I have no idea how it works, what it's actually for, but I am assuming, after doing some searching, that it can be used just to add additional SATA/Storage drives to a system.

 I want to add just 2 backup drives to what I have already, but all my SATA ports are being used and I have 3 M.2's going in slots _1 _2 and _5.

So, question, I don't see any conflicts in the user's manual, but are there any limitations or downsides to using the SlimSAS for additional Sata storage?

thanks
