Overview
Popular media, packages and video segments have different read patterns. SSDs are one part of the chain; networking, concurrency, caches and application processing also affect the experience.
This is a hot-storage selection guide, not a promise about specific media, IOPS, latency or available regions. Confirm configurations and performance through actual service information and testing.
Distinguish small-object and large-file workloads
Many small files can emphasize concurrency and per-read overhead, while large files need sustained transfer and interruption recovery. One sample cannot represent every application.
Images and page assets
Observe object counts, concurrent requests and the wait on cache misses.
Video segments
Check sequential reading, multiple bitrates and random access during seeking.
Packages and archives
Verify long transfers, range requests and bulk-release behavior.
Find what actually limits delivery
When networking or application processing dominates, faster disks may make little difference. Separate end-to-end timing into stages before choosing where to invest.
| Stage | Observation method |
|---|---|
| Storage reads | Representative objects under concurrent load with latency distributions |
| Transfer | Same-region and cross-region reads across sizes and devices |
| CDN caching | Hits, misses and expired-object requests separately |
| Application work | Authorization, dynamic generation and database waits |
Use appropriate retention for each data class
Popular assets and historical archives do not necessarily need the same configuration. Consider retrieval time, recovery goals and operational complexity rather than price alone.
- Keep predictable read paths and capacity headroom for hot data.
- Confirm retrieval delays, retrieval charges and acceptable waiting for infrequently used data.
- Review changing popularity so temporary hot spots do not consume premium resources indefinitely.
