WDS500G1R0A-68A4W0 WD Red SA500 500GB SATA 2.5" Server SSD

High-Performance 2.5in SATA NAS/Server SSD engineered for 24x7 reliability with the WDS500G1R0A-68A4W0

The WDS500G1R0A-68A4W0 is a 500GB 2.5in internal SATA SSD designed for always-on NAS and SMB server roles where predictable latency and stable throughput matter more than peak PCIe bandwidth. Integrated TLC NAND and a SATA 6Gb/s interface make it a practical fit for server backplanes and storage bays that prioritise broad compatibility, controlled thermals, and serviceability, including hot-swap capable environments.

In architectures where CPU and memory resources are allocated to file services, virtualization, or edge applications, the WDS500G1R0A-68A4W0 supports responsive boot, metadata, and read-heavy application tiers without consuming PCIe lanes needed for GPUs, NICs, or accelerators. With sequential performance up to 560 MB/s read and 530 MB/s write and up to 95K/85K 4K IOPS, it helps reduce queue depth amplification for OS volumes and cache tiers, while endurance of 350 TBW (0.384 DWPD, 5-year basis) aligns to sustained duty cycles.

Why Choose the WDS500G1R0A-68A4W0?

The WDS500G1R0A-68A4W0 provides a balanced density-to-performance profile for NAS boot pools, mirrored OS disks, and read-optimised service volumes where operational continuity is critical. Its 2.0M hours MTTF supports enterprise reliability expectations, and the SATA form factor simplifies scaling across mixed fleets, enabling consistent deployment patterns and straightforward spares strategy.

WD engineering focuses on dependable storage behaviour for continuous operation, pairing mature controller logic with NAND management that supports stable performance under sustained uptime requirements and aligns with modern data centre serviceability and lifecycle planning.

Key Applications:

• NAS boot volumes
• Metadata and cache tiers
• Read-heavy OS and application disks
• SMB file server storage
