WESTERN DIGITAL Blue SN550 500GB M.2 NVME Gen 3 Solid State Drive ( SSD )

The Western Digital Blue SN550 is a 500 GB M.2 2280 internal solid-state drive designed to bring NVMe performance to mainstream desktops and laptops. It connects via a PCIe Gen 3 interface, delivering sequential read speeds of up to 2,400 MB/s and sequential write speeds of up to 1,750 MB/s — a substantial leap over traditional SATA-based SSDs, which typically top out well below 600 MB/s. Western Digital engineered the SN550 with its own in-house controller and firmware, paired with 3D NAND flash memory. This combination is intended to deliver consistent, optimised performance across everyday workloads including productivity applications, content creation, casual gaming, and large file transfers. The drive operates within a maximum power envelope of 3.5 W, making it well-suited for compact and thin-and-light systems where thermal and power budgets are limited. The slimline M.2 2280 form factor (80 mm × 22 mm × 2.38 mm; listed dimensions 3.15" × 0.87" × 0.09") means installation is tool-friendly in virtually any system with an M.2 slot supporting PCIe NVMe. The drive ships without a heatsink, so users should verify motherboard or chassis clearance before purchasing a separate thermal solution. Western Digital bundles its Dashboard software, which provides real-time health monitoring, firmware update notifications, and drive status at a glance — useful for tracking the long-term condition of the SSD.
