Seagate ST2000VX002 SV35 2TB Surveillance Internal Hard Drive

The Seagate ST2000VX002 SV35 Series is a 2TB internal hard drive engineered specifically for the demanding requirements of video surveillance systems. Unlike standard desktop hard drives that are optimized for a mix of random reads and writes, the SV35 uses surveillance-tuned firmware that prioritizes sustained sequential writing — the exact workload pattern generated by DVR and NVR systems recording from multiple cameras around the clock. The 64MB cache buffer helps manage data flow from concurrent video streams, reducing the chance of dropped frames or recording gaps even under heavy multi-camera loads.

Running at 5900RPM with a SATA 6Gb/s interface, the SV35 strikes a deliberate balance between performance and reliability. The lower rotational speed compared to 7200RPM drives generates less heat and vibration, which is critical in surveillance enclosures that run continuously and often house multiple drives. The standard 3.5-inch form factor ensures compatibility with the vast majority of NVR and DVR hardware on the market. Backed by Seagate's 5-year limited warranty, this drive is designed for the specific demands of always-on surveillance recording rather than general-purpose computing.
