Western Digital Ultrastar 7K6 4TB 12Gb/s SAS Hard Drive with 7200 RPM, 256 MB Buffer, 512e Format, and 5-Year Warranty for Data Center, Server, and Enterprise Storage Deployments
The Western Digital Ultrastar 7K6 HUS726T4TALS204 (0B35919) is a 4TB enterprise SAS hard drive that delivers 12Gb/s SAS interface speed, 7200 RPM spindle performance, and 256 MB buffer in a standard 3.5-inch form factor for data center and server storage applications. The Ultrastar 7K6 is designed as a drop-in capacity tier for traditional storage and server workloads where lower-capacity drives provide the most economical cost per bay while still delivering the random and sequential performance that enterprise applications require, with 12% faster performance than the prior-generation Ultrastar 7K6000.
The 512e disk format provides sector-level compatibility with modern operating systems and storage controllers, while the 12Gb/s SAS interface provides dual-port connectivity for multipath I/O and high-availability storage architectures. At 1.58 lb in a standard 3.5-inch chassis, the Ultrastar 7K6 installs in any server or storage enclosure that accepts standard LFF drives. Western Digital backs the Ultrastar 7K6 with a 5-year limited warranty and REACH/RoHS 2 environmental compliance for enterprise procurement requirements.
Where the WD Ultrastar 7K6 4TB Fits
- Data center block and file storage tiers where the 4TB capacity provides economical cost per bay for workloads that do not require maximum density, the 12Gb/s SAS interface supports dual-port multipath I/O for high-availability controller configurations, and the 7200 RPM spindle with 256 MB buffer handles mixed read/write enterprise workloads with consistent latency
- Server boot and application storage where the 4TB capacity provides sufficient space for operating systems, application binaries, and local working data, the SAS interface delivers reliable enterprise-grade connectivity with error recovery and command queuing, and the 512e format provides native compatibility with modern server operating systems including Linux
- Distributed and scalable computing architectures where lower-capacity drives address architecture limitations in systems that benefit from more spindles per unit of storage, the 3.5-inch form factor fits standard server and JBOD enclosures, and the 5-year warranty with enterprise-rated reliability reduces replacement frequency in large drive fleets
