Tiered storage economics Why a bigger disk is the wrong answer
Adding capacity does not stop the archive from growing; it only postpones the same problem.
At this scale cost scales with access frequency, not with volume.
Most of an archive is read a few times a year, and keeping that data on the fastest, most expensive tier buys you nothing.
Moving between tiers is not a manual job. Lifecycle policies push objects down by age and access frequency:
same data, same address, same availability —
with a materially lower retention cost.
