Enterprise Performance 15K HDD

Performance You Need, Versatility You Want, Affordability You Demand

  • Accelerates I/O operations and completes more transactions faster — even during peak demand
  • At 900 GB, stores 50% more mission-critical data than any other 15K HDD
  • Optimizes TCO with higher capacity at lower cost than high-performance alternatives
  • Delivers more predictable performance (up to 27% SDR over previous generation ) while helping to protect data from corruption due to unexpected power loss
  • Supports all drive formats including 512 native and a single Fast Format™ model for advanced formats (4Kn and 512e) that simplifies HDD management
  • Industry-leading read caching with TurboBoost™ technology for optimum response times — perfect for OLTP applications
  • Advanced Write Caching feature utilizing enhanced algorithms for the industry’s highest mission-critical storage workload performance efficiencies
  • Uses traditional NAND and advanced algorithms to promote hot data and achieve performance improvement (up to 2.6× improvements over last generation )
  • Enables high density with power efficiency due to lower power and cooling requirements — ideal for space - and power-constrained enterprise data centers
  • Widely accepted, proven sixth-generation technology for reliable access to demanding high performance applications.

Best-Fit Applications

  • 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


This drive is compatible with laptops that accept 2.5" x 15mm SFF SAS drives.
