SV35 series hard drives now leverage extremely small tracks, measuring a mere 75 nanometers in width, while delivering reliable read-write functionality, even in higher-vibration environments. Seagate Acu Trac servo technology makes this nano-sized track pitch possible, providing accurate read-write data capability with fast 7200-RPM performance.SV35 series drives are tuned & tested for the rigors of a video surveillance workload, which is characterized by high write frequency in an always-on environment. In addition, specific features allow integrators to fine-tune the storage solution to optimize & manage power, monitor & manage temperature, or even characterize reads & writes for data or video payloads.
