WDS400T3B0A-00C7K0 WD Blue SA510 4TB SATA 2.5" Server SSD

High-Density 2.5in SATA Enterprise SSD for OS and Capacity Expansion with the WDS400T3B0A-00C7K0

The WDS400T3B0A-00C7K0 is a 4TB 2.5in SATA 6Gb/s internal SSD designed to modernise storage tiers in desktops, workstations, and entry servers where CPU and memory upgrades are constrained but storage latency and responsiveness remain critical. It aligns well with general compute platforms that rely on conventional SATA backplanes, delivering predictable throughput for boot volumes, application stacks, and large working sets without requiring PCIe lane budget or NVMe-capable bays.

Within a system architecture, the WDS400T3B0A-00C7K0 complements DDR4/DDR5 memory hierarchies by moving hot datasets and frequently accessed binaries from HDD to flash, reducing wait states and improving service time under mixed queue depths. Its SATA interface supports broad controller compatibility, while performance up to 560 MB/s read and 520 MB/s write and up to 90K/87K 4K IOPS targets read-mostly and light write patterns. With 600 TBW endurance and 2.25M hours MTBF, the WDS400T3B0A-00C7K0 is suited to stable duty cycles rather than heavy write-intensive logging.

Why Choose the WDS400T3B0A-00C7K0?

The WDS400T3B0A-00C7K0 delivers a pragmatic density-to-performance profile for fleets standardised on SATA, enabling straightforward drop-in upgrades with minimal revalidation. It supports scalable deployment logic for boot consolidation, bulk flash tiers, and workstation refresh projects where power efficiency and predictable reliability are required at volume.

WD engineers the SA510 series with a focus on controller and firmware stability, consistent compatibility across common SATA implementations, and operational reliability metrics aligned with modern data centre and enterprise client standards.

Key Applications:

• OS and application boot volumes
• Workstation and desktop storage refresh
• Read-mostly analytics staging
• Virtualisation host boot and utility tiers
• Content libraries and project repositories
