Trusted. Efficient. Versatile.
For everything Enterprise storage, there's Exos E—the safest and most powerful way to traverse the datasphere and harness its full potential. Always on and always working, the Exos E series of hard drives is loaded with advanced options for optimal performance, reliability, security and user-definable storage management. Built on generations of industry-defining innovation, Exos E is designed to work and perform consistently in enterprise-class workloads.
The Datasphere's Only 2.5-Inch Nearline Hard Drive
The Seagate Exos™ 15E900 enterprise hard drive is the world's fastest hard drive, with capacities up to 900GB in a 2.5-inch form factor, and is intended for traditional data centers where density, power consumption and data integrity are paramount.
Seagate Exos™ 15E900 series delivers faster time-to-data and is intended for use in data centers where density, power consumption and data integrity are paramount especially during peak demand workloads.*
- Up to 100% faster random write performance** with Enhanced Caching that accelerates OLTP, VDI, web server and database applications.
- Simplify data center integration with Fast Format™ models which can be addressed as 512 emulation and re-serviced to 4K native formats.
- Seagate Secure™ capabilities ensure authentic and trusted products from a secure supply chain, available with hardware-based encryption (SED), Instant Secure Erase (ISE), TAA compliance and FIPS 140-2
- High-performance, mission-critical enterprise servers requiring 24×7 availability
- Highly reliable blade, pedestal, rack and tower servers
- Transaction-based applications, like OLTP, databases, HPC and Big Data analytics
- Power- and space-constrained data centers
- Compliance and data security initiatives

Performance You Need With the Affordability You Demand
Exos 15E900 hard drives accelerate I/O operations and complete more transactions faster—even during peak demand. The 900GB model Exos 15E900 was the first to store 50% more mission-critical data than any other 15K hard drive. 1 By providing higher capacities at lower cost than high-performance alternatives, Exos 15E900 drives help optimize TCO. They deliver more predictable performance (up to 27% more sustained data rate than previous generation 1 ) while helping to protect data from corruption due to unexpected power loss.
Unrivaled Versatility Is Key
The Exos 15E900 supports all drive formats, including 512 native and a single Fast Format TM model for advanced formats (4Kn and 512e) that simplifies drive management. Industry-leading read caching with TurboBoost technology for optimum response times is perfect for OLTP applications. The Advanced Write Caching feature utilizes enhanced algorithms for the industry’s highest mission-critical storage workload performance efficiencies. The Exos 15E900 uses traditional NAND and advanced algorithms to promote hot data and meet performance requirements (up to 2.6× improvements over last generation1). By enabling high density with power efficiency, Exos 15E900 drives are ideal for space- and power-constrained enterprise data centers. Widely accepted, proven sixth-generation technology provides reliable access to demanding high-performance applications.
Industry-Leading Data Security Features
Seagate Secure TM models provide hardware-based security to help protect data-atrest. With Instant Secure Erase, drive retirement is safe, fast and cost-efficient. Seagate Secure models meet the NIST 800-88 media sanitization specification and support the Trusted Computer Group (TCG) standard.2
