HDD
A conventional high-capacity storage device based on magnetic platters and heads. It offers low cost per unit of capacity and is commonly used for warm data tiers and object storage, where access is infrequent and predictable.
Timeline (last 90 days)
Modern data centers typically divide storage media into three tiers by access frequency and performance requirements: the hot data tier uses NVMe SSDs or memory, the warm data tier uses high-capacity HDDs or object storage, and the cold data tier uses tape or optical disc libraries.
