My dealer offers two types of hard drives with roughly the same capacity:
-
Brand new CMR drive: 16TB for $598
-
Refurbished SMR drive: 14TB for $110
I plan to store important data on the CMR drive, and surveillance footage on the SMR drive. The footage will only be kept for 90 days. If the SMR drive fails, I’ll just re-record the footage. It’s best to put both types of drives in the same server to save on electricity costs.
“I plan to use 4 SMR drives. The attached picture shows the chassis.”
