Question on drive connectivity

I currently have UnRaid 6.10.2 up and running with 4 drives connected directly to SATA connections on the mobo.  These connections are SATA2 so I want to utilize a spare HBA I have and breakout the SAS connections into SATA3.  Can I just move my drives to those connections since there is technically no traditional RAID or do I have a risk of data loss and corruption?

Yes, the drives are identified by Unraid using their Serial Numbers. Unless the old or the new controller do not pass them through as is, you should be OK.

 

Just as a side note, SATA2 is just fine for HDDs as they cannot saturate the interface (3Gbps).

And depending on the model of HBA, it might not be great to attach SSDs to it as older controllers cannot TRIM.

Ok. Thank you for the info.
