Cctv Hard Disk
Overview
Product sourcing insights & recommendations
The market for CCTV hard disks is evolving rapidly, with a shift toward AI-integrated storage and high-capacity units (24TB+) to support 4K/8K resolution video. The global market is projected to reach $15.55 billion by 2031, driven by a 7.3% CAGR. Surveillance-grade drives remain critical due to their ability to handle 24/7 write-heavy workloads (90-95% write) and manage rotational vibration in multi-drive systems, features standard desktop drives lack.
Key players like Western Digital (Purple/Purple Pro) and Seagate (SkyHawk/SkyHawk AI) are leading with firmware-optimized technologies such as AllFrame AI and ImagePerfect AI, which prevent frame loss during simultaneous recording and AI metadata analysis. Wholesale pricing currently ranges from ~$46 for 4TB units to ~$600 for high-end 10TB models, depending on volume and AI capabilities.
Detailed findings on market trends, technical differentiators, and product evaluations are included in the report below.
