WESTERN DIGITAL Blue SN580 1TB M.2 NVME Gen4 Internal Solid State Drive ( SSD )

The Western Digital Blue SN580 1TB NVMe SSD (model WDS100T3B0E) is a PCIe Gen 4.0 x4 drive built for content creators, professionals, and everyday users who demand fast, reliable storage in a compact form factor. Running on the PCIe Gen4 NVMe 1.4b interface, it delivers sequential read and write speeds of up to 4,150 MB/s, making it significantly faster than Gen3 predecessors for loading large applications, editing video projects, or transferring media assets. Random read performance reaches up to 600K IOPS and random write up to 750K IOPS (4KB, QD32, T16), ensuring snappy responsiveness even during demanding multitasking sessions. Western Digital’s nCache 4.0 technology accelerates burst file copies by intelligently using a portion of the TLC NAND as a high-speed buffer, reducing latency when moving large batches of photos, 4K footage, or project files. The drive uses Western Digital TLC (Triple-Level Cell) NAND in an M.2 2280 single-sided layout (M key), making it compatible with laptops that have restricted clearance behind the M.2 slot. At just 5.5 g and 2.38 mm in height, it adds virtually no weight or bulk to any build. Power efficiency is a standout attribute for mobile users: average active power sits at just 65 mW, while PS5 sleep state drops consumption to 3.3 mW, helping to extend laptop battery life during light workloads. Operating temperatures span 0 °C to 85 °C, and the drive is rated to withstand 1,500G shock at 0.5 ms half sine. Security features include TCG Pyrite 2.01 and ATA Security Passthrough over NVMe, providing hardware-level access control. The SN580 1TB is backed by a 5-year limited warranty and carries a mean time to failure (MTTF) rating of 1.5 million hours, with a 600 TBW endurance rating. Certifications include FCC, CE, TUV, UL, RCM, KCC, BSMI, VCCI, and others for broad regional compliance.
