## Long description

The Internal 3.5" SAS Hard Drive Toshiba MG04 6TB 7200 RPM 128 MB (HP Enterprise 861590-B21) is a 3.5-inch nearline enterprise-class hard disk designed for server and storage systems that require high-capacity, reliable sequential and random access. With 6 TB of usable capacity, a 7,200 RPM spindle speed and a 128 MB cache, this drive is intended for archival, database and virtualization workloads. The drive offers a high MTBF rating to support continuous operation in data center environments and a compact 3.5-inch form factor to fit standard server bays.
Advantages
The drive combines high capacity per spindle with persistent write cache technologies that help protect data during sudden power loss and contribute to improved performance and reliability. Compared with prior 4 TB models, the 6 TB design delivers better power efficiency per terabyte, reducing watts per stored data and lowering operational costs in high-density deployments. Support for SAS command sets and model options with sanitize instant cryptographic erase (SIE) provide additional data security and erase flexibility for enterprise workflows.
Suitable for
Nearline archival storage and cold data repositories
Virtualization hosts and VM storage pools
Database systems requiring reliable sequential throughput
Tape replacement or tiered storage in data centers
High-density scale-out storage enclosures

Capacity: 6000 GB (6 TB)
Rotational speed: 7200 RPM
Cache size: 128 MB
Mean time between failures (MTBF): 1,400,000 hours
Power efficiency: improved watts per terabyte versus previous 4 TB generation
Weight: 0.77 kg
Persistent write cache technology for improved data protection on power loss
How to use
Install the drive in a compatible 3.5-inch server or storage bay supporting SAS/SATA interfaces and ensure the enclosure firmware and host controller are up to date. Configure the drive within your RAID or storage pool according to your redundancy and performance requirements. For best results in enterprise environments, follow the server vendor’s drive handling and mounting procedures, and verify drive health through monitoring tools and SMART-enabled diagnostics. When replacing or upgrading drives, follow hot-swap guidelines if supported by the system to avoid service disruption.
Usage recommendations
Use this 6 TB Toshiba MG04 drive for workloads that prioritize capacity and sequential throughput. Configure appropriate data protection (RAID, replication) and take advantage of persistent write cache and SIE-capable models where fast secure erase or enhanced power-loss protection is required. Monitor temperature and vibration levels in high-density racks to maintain long-term reliability.
