SDASB8Y-256G WD PC SA530 256GB SATA 2.5" Consumer SSD

High-Performance 2.5" SATA Boot SSD engineered for reliable OS volumes with the SDASB8Y-256G

The SDASB8Y-256G is a 2.5" internal SATA 6Gb/s SSD designed to stabilise server and workstation boot storage where predictable latency and consistent read behaviour matter more than write-intensive throughput. As a dedicated OS and application boot device, the SDASB8Y-256G helps isolate system I/O from data-plane workloads, improving overall platform responsiveness under virtualisation hosts, edge gateways, and general-purpose compute nodes.

Built on TLC NAND, the SDASB8Y-256G targets read-optimised caching and light write profiles, with up to 550MB/s sequential read and 525MB/s sequential write to efficiently service boot storms, patch cycles, and log-in peaks. Its SATA interface aligns with broad backplane compatibility and mixed-generation server fleets, enabling straightforward deployment into existing 2.5" bays without consuming PCIe lanes needed for accelerators, high-speed NICs, or NVMe tiers. Endurance is specified at 0.2 DWPD over 5 years and 100TBW, while 1.75M hours MTTF supports standard enterprise maintenance cycles and controlled refresh strategies.

Why Choose the SDASB8Y-256G?

The SDASB8Y-256G provides a practical density-to-reliability profile for boot and read-dominant roles, enabling consistent provisioning across racks and remote sites. By standardising on the SDASB8Y-256G, IT teams can simplify imaging, spares management, and lifecycle replacement while keeping performance predictable within the SATA envelope.

WD engineers the PC SA530 family to prioritise compatibility, validated operational behaviour, and efficient power characteristics for always-on environments. With low idle power and a proven SATA architecture, the SDASB8Y-256G aligns with data centre standards that value controlled thermals, repeatable deployment, and manageable serviceability.

Key Applications:

• Server OS and hypervisor boot volumes
• Read-heavy caching tiers
• Edge compute and branch infrastructure
• Workstation and legacy SATA bay upgrades
