Hard drive Seagate AI Skyhawk 4TB 3.5" SATA 6Gb/s - ST4000VX016

Seagate AI Skyhawk 4TB is a 3.5" hard drive designed specifically for video surveillance systems. It combines a high capacity of 4TB with a SATA3 6 Gb/s interface to handle continuous recording from multiple cameras. As a surveillance series drive, it is optimized for constant operation and sequential recording, rather than typical desktop workloads. The added 256 MB cache helps for smoother recording and playback of video streams.

What you get is a stable foundation for DVR and NVR systems that operate 24/7. The 4TB capacity gives you space for long-term archiving of recordings, allowing you to maintain history from a large number of cameras with appropriate resolution and compression settings. The SATA3 6 Gb/s interface provides sufficient bandwidth for simultaneous recording and video playback without overwhelming the system. With 256 MB cache, the drive better swallowscontinuous video streams, reducing the risk of stuttering during recording or playback. The form factor 3.5" means easy installation in most recorders, NVR boxes, and standard PC cases.

• Capacity 4TB – enough space for a long archive of video surveillance from multiple cameras and continuous recording.
• Type: Surveillance – designed for constant 24/7 recording, as used in DVR and NVR systems.
• Interface SATA3 6 Gb/s – wide compatibility with modern motherboards and recorders and good bandwidth for multiple video streams simultaneously.
• Form factor 3.5" – standard size for desktops and recorders, making integration into existing systems easier.
• 256 MB cache – smoother continuous recording and faster access to frequently used data.
• Weight 490 g and dimensions 101.6 x 147 x 20.2 mm – compact solution that fits in typical video surveillance chassis.
• 36 months warranty – additional peace of mind for a device that will run non-stop.

It is suitable for home and small business video surveillance systems, DVR/NVR solutions, and PC-based recorders, where the main scenario is continuous recording. It can also be used as mass storage in a desktop computer, but its true strength lies in surveillance workloads, not as a primary drive for gaming or heavy applications.

The combination of 4TB capacity, surveillance-oriented design, and SATA3 6 Gb/s interface makes this Seagate Skyhawk a solid choice if you want a reliable drive for 24/7 video recording. The most meaningful aspect here is the balance between volume, cache, and specialization for surveillance scenarios.
