I just added a new nvme ssd to my single cache unraid. So now I have a raid 1 cache pool.

 

The main cache age is almost 3 years old and its endurance remaining is 61%. The new cache or cache 2 is a brand new mirror drive.

Swapping my cache 2 to be a main cache would make any difference? I'm afraid my old main cache will corrupt much sooner than the cache 2.

What is the safest way to swap these 2 cache drive, if I have to? Do I have to swap physical slots too? The main cache is plugged to the onboard nvme slot. The new cache is on the pcie 4x 3.0 to m2 card adapter.

 

Thanks

Nope, in a mirror they are both used the same.

Thanks.
