The WD Blue SN5100 500GB arrives in M.2 2280 form factor, fitting standard NVMe slots with single-sided PCB design and weighing approximately 7 g. This PCIe Gen4 x4 drive delivers sequential read speeds up to 5,600 MB/s and sequential write speeds up to 4,000 MB/s, making it a capable option for storage architects and IT procurement teams evaluating next-generation NVMe solutions.

Built by Western Digital under the WD Blue SN5100 series, the drive uses 3D NAND TLC flash memory paired with HMB (Host Memory Buffer) architecture for DRAM-less performance. The WDS500G5B0E part number provides 500 GB of capacity and operates across a 0°C to 70°C temperature range, with idle power consumption of approximately 50 mW and active read power at approximately 6.5 W. The NVMe protocol interface ensures compatibility with modern enterprise platforms requiring high-speed storage expansion without legacy baggage.

Enterprise Application Scenarios

• High-throughput data center refresh projects where PCIe Gen4 sequential performance directly improves boot times and application launch responsiveness
• Virtualized workloads benefiting from the 5,600 MB/s read capability to reduce VM provisioning windows and snapshot recovery latency
• Edge computing deployments requiring low idle power consumption of approximately 50 mW to minimize thermal output in space-constrained cabinets
• Mixed-workload storage arrays where 4,000 MB/s sequential write speed and DRAM-less design reduce overall system cost-per-TB without sacrificing throughput
• Compact server configurations leveraging the 80 mm x 22 mm x 2.38 mm dimensions to maximize density in single-socket or dual-socket appliances

Western Digital backs this drive with established enterprise support channels.
