Checksum errors

I have a DS920+ with 4 drives, two 12tb and two 8tb. The 12tb are newer than the 8tb and have less hours on them. All 4 drives are in SHR

I noticed in log center that in the last month tons of my files, including Time Machine backups are throwing check sum errors.

I don’t have extra ram or cache ssd installed. Could the age of the two 8tb drives be causing this?
