A 911 media store confuses volume sharing rules with disk performance tiers. How should the admin separate those concepts?
Select an answer to reveal the explanation.
Short Explanation
Access mode is the sharing rule—who can open the filing cabinet at once. StorageClass is which cabinet you bought—SSD, cheap HDD, encrypted vault. Mixing them up is like thinking “ReadWriteOnce” means “turbo disk.” Different knobs, different jobs.
Full Explanation
Access modes (RWO, ROX, RWX, and related) constrain concurrent mount and sharing semantics. StorageClasses select provisioners and parameters such as disk type, IOPS, or zone behavior. They are complementary, not synonyms; kube-proxy does not equate them, and RWO does not imply the highest performance class.
