Seagate SkyHawk vs WD Purple: Which Surveillance HDD is Better for Your Needs?

When choosing a hard drive for surveillance systems, two names dominate the market: Seagate SkyHawk and WD Purple. Both are designed for 24/7 operation, but they cater to slightly different needs in video storage. As we enter Q4 2025, let’s examine how these drives compare in today’s evolving surveillance landscape.
