WDS400T3B0A WD Blue SA510 4TB SATA 2.5" Server SSD

High-Density 2.5in SATA Internal SSD for OS and Data Volumes with the WDS400T3B0A

The WDS400T3B0A is a 4TB 2.5in, 7mm internal SSD engineered for SATA 6Gb/s platforms where predictable latency, simplified serviceability, and broad server/workstation compatibility are required. In mixed CPU environments, it provides a stable boot and application tier for Windows or Linux deployments, while keeping storage integration straightforward through standard SATA backplanes and cabling.

Built on 3D TLC NAND, the WDS400T3B0A targets read-optimised and light write-duty profiles, balancing capacity with controlled endurance characteristics for sustained enterprise operation. With sequential performance up to 560MB/s read and 520MB/s write, it fits well behind PCIe expansion tiers as a cost-effective OS volume, staging disk, or general-purpose SSD refresh in systems without NVMe bays. Random performance up to 90K/87K IOPS (4K) supports responsive application launches, VDI-like user profiles, and metadata-heavy tasks when properly queued and aligned.

Why Choose the WDS400T3B0A?

The WDS400T3B0A delivers a practical density-to-performance profile for SATA estates that need consistent boot behavior, simplified spare management, and scalable rollouts across desktops, workstations, and small servers. With 600TBW endurance, 2.25M hours MTBF, and a 5-year duty model, the WDS400T3B0A supports reliable fleet standardisation where write intensity is controlled and monitoring is enforced.

WD designs the WDS400T3B0A with a focus on predictable operation, validated firmware behavior, and compliance with common 2.5in storage form-factor standards, enabling straightforward qualification in existing data centre and edge stacks.

Key Applications:

• Workstation boot and application volumes
• Desktop and small server SATA SSD replacement
• Read-optimised departmental file and project storage
• VDI user profiles and light-content repositories
