Seagate Skyhawk 3TB 3.5? 7200RPM SATA 64MB Cache

ImagePerfect™ firmware supports 24×7 surveillance-optimized workloads tuned to record ~90% of the time and play back video footage the remaining 10%, and supports more cameras recording at higher resolutions than traditional drives.
Workload rating of 180TB/year allows SkyHawk to perform reliably in write-intensive surveillance systems—3× the workload rating of a desktop-class drive.
NVR-ready design allows drives to maintain performance in RAID and multi-drive systems, giving customers the flexibility to grow with the booming NVR market and scale their systems when more storage is needed.
ATA streaming support sustains recordings from up to 64 HD cameras for smooth, uninterrupted footage.
Up to 10TB or over 2000 hours of HD video storage supports an increased number of cameras and helps to ensure longer data retention periods are met.
1M hours MTBF represents an improved total cost of ownership (TCO) with reduced maintenance costs.
Lower power consumption means a reduction in heat emissions, which improves reliability in surveillance solutions.
Tarnish-resistant components help protect drive from environmental elements, increasing field reliability.
