Final answer:
Warm is not considered a conventional Data Storage Tier; typical tiers include Hot, Cold, and Archived, which reflect varying access needs and cost efficiencies.
Step-by-step explanation:
The term Data Storage Tier refers to the stratification of data storage based on the performance, cost, and frequency of data access. Common tiers in data storage solutions include Hot, Cold, and Archived. The Hot tier is used for data that needs to be accessed frequently and quickly. Cold storage is for data that is infrequently accessed and does not need to be retrieved quickly. Archived storage is used for data that is rarely accessed and kept for long-term retention or compliance purposes. In this context, Warm is not typically considered a conventional data storage tier.
