WESTERN DIGITAL Blue SN5100 500GB M.2 NVMe Gen4 Solid State Drive ( SSD )

The Western Digital Blue SN5100 500GB is an internal M.2 2280 NVMe solid-state drive built on the PCIe Gen 4.0 interface. Designed for creators, students, and professionals who need a responsive everyday drive, it delivers sequential read speeds of up to 6,600 MB/s and sequential write speeds of up to 5,600 MB/s — a meaningful step up in throughput compared to PCIe Gen 3 alternatives. Storage capacity sits at 500 GB, making this drive a practical choice for operating-system installs, creative project libraries, and application caches. The drive is built using SanDisk 3D CBA NAND flash technology, Western Digital’s next-generation layered NAND architecture that aims to balance performance density and endurance. Complementing the NAND is SanDisk nCache 4.0, a dynamic caching layer that accelerates burst writes when transferring large files or project folders. The drive ships with a product code of WDS500G5B0E and carries a rated Total Bytes Written (TBW) endurance figure of 300 TBW, giving buyers a concrete measure of long-term write durability. Western Digital backs the SN5100 with a 5-year limited warranty, which provides recourse in the event of premature drive failure. Two complementary software utilities are available as free downloads: Acronis True Image for SanDisk, which supports data migration from an existing drive to the SN5100, and the SanDisk Dashboard, which enables health monitoring and firmware update checks. The M.2 2280 form factor (22 mm wide, 80 mm long) is compatible with the vast majority of modern laptops and desktop motherboards that include an M-key slot. No heatsink is included in the box, so buyers with thermals-sensitive systems may wish to verify case airflow or add an aftermarket heatsink.
