HDD HGST 4TB 3.5" SAS HUS724040ALS640-RFB

The HDD HGST 4TB 3.5" SAS HUS724040ALS640-RFB is a 3.5-inch enterprise-class hard disk drive from HITACHI (HGST) designed for server and data center environments. With 4 TB capacity, a 7200 RPM spindle speed and a 64 MB cache, the drive provides sustained throughput and low latency for mixed and sequential workloads. The SAS interface offers full-duplex data transfer, improved error recovery and enhanced data integrity features expected in enterprise storage arrays. The drive is suitable for deployment in RAID arrays, JBOD enclosures and scale-out storage systems that require robust performance under continuous operation.

Advantages

The HGST 4TB SAS drive combines high capacity with a 7200 RPM rotational speed and a 64 MB cache to support faster read/write operations compared with lower-RPM models. The SAS interface ensures greater reliability and advanced error handling compared to typical SATA drives, making it appropriate for enterprise-grade deployments. The drive is engineered for high workload rates and continuous operation, offering consistent performance and compatibility with common server RAID controllers and storage platforms.

Suitable for

• Enterprise servers and rack-mounted storage systems
• Database and virtualisation workloads
• RAID arrays and redundant storage configurations
• Backup and archival systems requiring large capacity
• Scale-out storage and NAS solutions in mixed-workload environments
