HDWR51GUZSVA Toshiba X300 Performance 16TB SATA 512 MB 3.5" Server HDD

High-Capacity 3.5in Enterprise SATA CMR HDD for 24/7 Bulk Storage with the HDWR51GUZSVA

The HDWR51GUZSVA is a 16TB 3.5in internal enterprise hard drive designed for high-density capacity expansion in SMB and enterprise servers, as well as DAS/NAS platforms with standard SATA drive bays. Built on a 7200 RPM mechanical platform with a 512MB cache, the HDWR51GUZSVA sustains predictable throughput for large sequential datasets while maintaining stable latency characteristics under continuous service conditions.

Using CMR recording and a 512e sector format, the HDWR51GUZSVA is optimized for RAID and ZFS-style storage stacks where consistent write behavior and rebuild predictability matter. The SATA interface supports broad interoperability across backplanes and host bus adapters, enabling scalable expansion without consuming PCIe lanes needed for compute, networking, or NVMe tiers. A helium-filled design reduces friction and heat, supporting dense multi-bay deployments in data center chassis and storage enclosures, while aligning with always-on bulk storage, backup targets, and content libraries.

Why Choose the HDWR51GUZSVA?

The HDWR51GUZSVA delivers a pragmatic density-to-cost profile for capacity-first architectures that still require 24/7 reliability and controlled operational behavior. For IT teams balancing storage growth, serviceability, and predictable array performance, the HDWR51GUZSVA integrates cleanly into existing SATA ecosystems and scales linearly across multi-drive RAID groups and tiered storage designs.

Toshiba engineers this class of enterprise-capable HDDs with a focus on sustained operation, mechanical stability, and tight manufacturing controls aligned with modern server and storage qualification processes. With a stated 0.6M hours MTTF/MTBF target, the platform supports long-lived deployments where uptime, rebuild resilience, and fleet consistency are key requirements.

Key Applications:

• RAID bulk capacity in rack servers
• DAS/NAS expansion in 3.5in SATA bays
• Backup repositories and archive tiers
• Media and content libraries
• General-purpose file storage
