Seagate Video SV35.5 Hard Drives
The SV35.5 Series drives are the only hard drives designed and optimised solely for video surveillance, with perpendicular recording technology and a 7,200 RPM spindle motor for maximum speed and multi drive SDVR performance, the SV35.5 Series drives are optimised for recording of multiple, simultaneous standard or high resolution video streams and designed for 24x7 operation and high write duty cycles. The SV35.5 Series has a full range of capacities, including 1 TB, 500 GB and 250 GB and the SATA interface enables increased video data rates of 6-Gb/ or 3-Gb/s. With low power consumption and reduced heat generation make the Seagate SV35.5 ideal for Video surveillance digital video recorders (SDVR), Video surveillance network digital video recorders (SNVR) and Direct and network attached JBOD video surveillance storage.
  Key Advantages
- The industry’s only surveillance-optimized hard drive platform with up to a 1TB capacity options.
- A hard drive series tested and tuned for high write-cycle workloads typical in video surveillance storage systems.
- 24×7 operational capabilities while maintaining high MTBF of 1M hours.
- Performance driven by a 7200-RPM base platform, with up to 32MB DDR2 DRAM and optimized write caching surveillance algorithms.
- 1TB-per-disk technology takes your surveillance storage further with lower cost/GB to support HD resolutions, enhanced performance and best-in-class support.
- Seagate AcuTrac servo technology provides accurate read-write operation even in challenging operating environments.
- 2A current-limited startup to support the use of embedded system power supplies.
- Spin control features enable power-on in standby mode or drive spin-down to conserve power and improve reliability during archival periods.
  Best-Fit Applications
- NVR
- Embedded SDVR
- Hybrid SDVR
- PC-based SDVR
