Designed for always-on, always-accessible 24×7 performance. Access data on your NAS any time, remotely or on site.
1M hours MTBF, 3-year limited warranty represents an improved total cost of ownership (TCO) over desktop drives with reduced maintenance costs.

Scale, Accelerate and Secure Your Mission Critical Data

- Scale capacity quickly within budget by using the industry’s highest capacity hard drive (2.4 TB) for mission critical applications
- A little flash goes a long way. Deliver reduced wait times and prevent applications from slowing down during peak usage.
- Deploy and repurpose storage quickly and anticipate future needs with the built-in advanced format capabilities of FastFormat™
- Upgrade capacity and performance with drop-in upgrades to existing server and storage solutions
- Prevent loss of sensitive data and help to ensure compliance with security policies while protecting data-at-rest

Meet Your Data Growth Needs

Building high-performance servers that can consistently and reliably manage the increasing demands of faster time-to-data is a challenge. And doing so economically can seem daunting — until now! Follow leading Enterprise IT Pros by selecting the Enterprise Performance 10K HDD, the only 24×7 HDD with the perfect combination of high capacity and cost-effective high performance. With capacities from 600 GB to 2.4 TB, the 2.5-inch footprint enables IT managers to optimise data centre space while keeping pace with data growth.

Delivering Consistently High Performance During Peak Demand

When it comes to delivering uncompromising performance and value, it’s tough to beat the legendary ninth-generation mission critical drive — the highest 10K performer on the market. The Seagate® Enhanced Caching feature accelerates read and write I/O operations, preventing applications from slowing down under peak usage conditions while speeding up revenue-producing transactions. The right amount of embedded flash allows advanced algorithms to promote hot data in order to achieve unprecedented read performance improvements.

Maximise Storage Investments for the Long Haul

Architecting storage infrastructure that easily adapts to rapidly changing workloads is only one part of the solution. The advanced format model can be addressed as 512 emulation or re-serviced as 4K native when your systems are ready — a true lifesaver in maximising your investment and responding quickly to the changing needs of your data centre. Plus Seagate Secure® encryption technology helps prevent sensitive data from being leaked or corrupted while helping to ensure compliance with security policies.1 Implementing Instant Secure Erase (ISE) allows you to quickly remove all data from the drive for repurposing or drive disposal. Features like PowerChoice™ and RAID Rebuild™ enable IT organisations to tailor efficiencies to their specific needs.

SkyHawk™ leverages Seagate's extensive experience in designing drives purpose-built for surveillance applications. ImagePerfect™ firmware is designed to ensure seamless video footage capture in 24×7 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.2 Included is RAID RapidRebuild™, which provides 3× faster volume rebuilds over traditional RAID rebuilds. Unparalleled data protection with included 3-year Rescue Data Recovery Services plan, helping protect important video data with Seagate's in-house data recovery services. 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. 1 M hours MTBF, 3-year limited warranty 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.
