The storage demand is likely to skyrocket exponentially due to the emergence of seedance2. GPT-3.5 brought about the text era, but the real video era is ushered in by seedance2. With just a few prompts, the storage consumed by video AI will reach hundreds of megabytes, and as the duration of AI video production increases, this size will grow even larger. The derived storage demand this time will be many times that of the original text. After all, there are indeed many people addicted to watching videos now, from infants to elderly people globally, no one can escape; they may not love reading books or news, but they absolutely love scrolling through short videos. Based on this, new investment demands will arise. The types of storage required for video AI will definitely differ from those for text AI. Gemini provides a record of the current storage architecture used by Douyin and YouTube. Currently, video storage is not a single medium but a complex multi-tiered hot and cold storage architecture (Tiered Storage Architecture). A. Architecture Components 1. Ultra-Hot Tier: Used to handle instantaneous traffic bursts (like videos just released by top influencers). • Type: NVMe SSD clusters + memory-level caching (Redis/Memcached). • Core Metrics: **IOPS (Input/Output Operations Per Second)** and extremely low latency. 2. Warm Tier: Used to store videos that are actively watched daily. • Type: High-performance enterprise-grade HDDs or large-capacity QLC SSDs. • Core Metrics: Balancing throughput and cost. 3. Cold/Archive Tier: Used to store long-tail videos from years ago that are hardly viewed. • Type: High-density helium HDDs or even physically isolated tape drives. • Core Metrics: Total Cost of Ownership (TCO) per TB. B. Pain Points: I/O Wall and Storage Islands In traditional architectures, storage is "static." But the AI video era (SeenDance 2) requires storage to transform from a "warehouse" to a "production line," which directly leads to the collapse of storage logic. From the current state and challenges of video company storage, three future development directions can be extended. Three Future Development Directions for Video AI Storage...
