WESTERN DIGITAL Blue SN5100 1TB M.2 NVMe Gen4 Solid State Drive ( SSD )

The Western Digital Blue SN5100 1TB NVMe SSD (model WDS100T5B0E) is a compact M.2 2280 internal solid state drive built on PCIe Gen 4.0 x4 technology. It is designed for mainstream desktops, laptops, and creative workstations where fast, reliable storage is a priority. With sequential read speeds of up to 7,100 MB/s and sequential write speeds of up to 6,700 MB/s, the SN5100 is positioned for demanding workloads such as editing large media files, loading game assets, and accelerating AI-assisted applications. Random read performance reaches 1,000K IOPS and random write performance reaches 1,300K IOPS, contributing to snappy system responsiveness during multitasking. The drive is built using SanDisk 3D CBA NAND technology, Western Digital's next-generation flash architecture. It also incorporates SanDisk nCache 4.0 caching technology, which helps maintain higher sustained write speeds when copying large files or project folders. At 5.7 grams and with dimensions of 3.15 × 0.87 × 0.09 inches, the SN5100 fits the standard M.2 2280 slot found in most modern motherboards and slim laptops. The drive ships without a heatsink, so compatibility with heatsink-equipped slots should be confirmed before installation. Endurance is rated at 600 TBW (terabytes written), which is suitable for a full workday of intensive read/write activity over several years. Operating temperature range is 0°C to 85°C (32°F to 185°F), with non-operating storage rated 40°F to 185°F. Western Digital includes a 5-year limited warranty with the SN5100, and buyers can download the SanDisk Dashboard for drive health monitoring and firmware updates. Acronis True Image for SanDisk is available as a free data migration tool.
