NEC Express5800 HDD 4TB 7200RPM SAS 12Gbps 3.5-inch

The NEC Express5800 4TB 7200RPM SAS 12Gbps 3.5-inch HDD is an enterprise nearline hard drive designed for high-capacity storage tiers within the Express5800 server family and iStorage M700/M5 hybrid configurations. Operating at 7200RPM with a 256MB cache buffer, the drive provides a balance of sequential throughput performance suitable for backup-to-disk targets, archive storage, and large-capacity NAS/NFS tiers that do not require SSD-class random I/O performance.

The dual-port SAS 12Gbps interface provides full path redundancy in enterprise RAID configurations, and the drive's vibration compensation technology (Rotational Vibration Safeguard) ensures stable operation in multi-drive chassis environments where mechanical vibration from neighboring drives can degrade performance and reliability. NEC validates these drives with its own RAID controller firmware to ensure that error recovery timings are configured correctly to prevent RAID rebuild failures during drive recovery operations.

With a 2.5 million hour MTBF rating and enterprise-class workload rating of 550TB/year, these drives are built for continuous 24/7 operation in demanding data center environments. They are commonly deployed in iStorage M700 expansion shelves as the NL-SAS capacity tier in automated tiering configurations, providing cost-effective bulk storage below SSD tiers managed by iStorage's auto-tiering engine.

Ideal for

• Backup-to-disk target (NAS or DAS tier)
• iStorage M700 NL-SAS capacity tier for auto-tiering
• Cold data archive and long-term retention storage
• Large-capacity file server in Express5800/R110j-1
• Media asset storage for video production environments
• Log archive and compliance data retention
