Adding 2nd Cache Drive Parity?

[gadget069]

Doing some poking around it seems that adding a second cache drive does not give you pairty but a raid 1 config? I was looking at having some redundancy for the cache drive, the primary cache drive was not new (Samsung Evo 860 ssd).

 

The second cache drive I added (EVO 850) also kicked out a crc error count. I'm assuming I dont want to use this drive anymore with it already having issues. Is there a particular process to remove the bad(?) cache drive I added? I have a new one coming today.

 

Thanks

Correct.

This is usually a bad SATA cable, replace it and see if the errors don't keep increasing.

The errors have not increased since the initial install. I do have different cables to try. I had picked up some CableCreation sata cables from Amazon. No issues with the other 4 I've used in this system

 

I still think I may replace this drive just in case. Nothing special to do when replacing this drive? It is not the primary chache drive.

 

Thanks
