WDS400T2R0A
High-Performance 2.5-inch SATA NAS SSD for Always-On Storage Tiers with the WDS400T2R0A
The WDS400T2R0A is a 4TB internal WD Red NAS SATA SSD engineered for predictable I/O behavior in multi-drive NAS chassis, where storage consistency and continuous service matter more than peak burst performance. In a typical SMB platform, CPU and memory resources are allocated to file services, snapshots, and lightweight virtualization, so the WDS400T2R0A focuses on low-latency access paths and steady throughput for cache tiers or all-flash volumes without demanding PCIe lane budget.
Using TLC NAND and a 2.5-inch SATA interface, the WDS400T2R0A integrates cleanly into existing backplanes and RAID sets while preserving expansion capacity for NICs and HBAs. The architecture supports sequential transfer rates up to 560MB/s read and 520MB/s write, with strong 4K random performance for metadata-heavy shares and VM datastore activity. With 0.3 DWPD for 5 years and 2,500TBW, the WDS400T2R0A aligns to moderate write intensity, balancing endurance with capacity density for edge and departmental deployments.
Why Choose the WDS400T2R0A?
The WDS400T2R0A provides an enterprise-relevant density-to-performance profile for SATA-based NAS fleets, enabling consistent service levels across mixed workloads while keeping operational risk low. Designed for 24/7 operation in multi-drive environments, the WDS400T2R0A supports scalable rollout strategies where standardization, predictable behavior, and lifecycle planning are primary deployment drivers.
WD engineers the Red NAS SSD line with a reliability-first approach, emphasizing continuous operation, validated compatibility expectations for NAS duty cycles, and alignment with modern data centre practices around capacity planning, RAID resiliency, and serviceability. With 2.0M hours MTBF and low power draw, the WDS400T2R0A helps control thermal and energy envelopes in dense storage nodes.
Key Applications:
- NAS SSD cache tier
- All-flash NAS volumes
- SMB shared file services
- VM datastore for edge deployments
