24x7 workloads can leverage up to 8 TB with drives designed for DVR and NVR systems. SkyHawk video drives are equipped with enhanced ImagePerfect™ and SkyHawk Health Management to help you sail through your toughest challenges.
Key Advantages
ImagePerfect™ firmware is designed to ensure seamless video footage capture in 24x7 surveillance workloads1 that record video from 64 HD cameras.
SkyHawk Health Management actively helps protect your surveillance storage by focusing on prevention, intervention, and recovery options. Included is RAID RapidRebuild™, which provides 3x faster volume rebuilds over traditional RAID rebuilds.
RV sensors built in allow drives to maintain performance in multi-bay systems, giving customers the flexibility to scale their systems when more storage is needed.
ATA streaming support enables recordings from up to 64 HD cameras for smooth, uninterrupted footage.
1M hours MTBF, 3-year limited warranty2 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.
1 SkyHawk surveillance drives are designed for always-on workloads of 180TB/year. For higher transaction workloads, see Seagate’s enterprise-class drive offerings.
2 Seagate does not recommend operating at sustained extreme temperatures. Operating at higher temperatures will reduce useful life of the products.
