Product Overview
The WD_BLACK SN850X is an internal solid-state drive designed for high-performance storage in compatible computers and gaming systems. This configuration provides 1TB of storage and uses an M.2 2280 form factor with a PCI Express Gen 4 x4 NVMe interface. Manufacturer part number WDS100T2X0E identifies the 1TB version represented by this product configuration.
The drive is designed to provide substantially faster storage access than conventional mechanical hard drives and earlier SATA-based solid-state drives when installed in a compatible PCIe system. Documented sequential read performance reaches up to approximately 7,300 megabytes per second under supported conditions. Actual performance varies with motherboard capabilities, workload, operating temperature, firmware, available PCIe lanes, system configuration, and remaining storage capacity. The bare-drive configuration does not include an integrated heatsink. Systems with limited airflow or sustained high storage workloads may require additional thermal management according to the computer or motherboard manufacturer’s recommendations.
