WD Black SN7100 1 TB (WDS100T4X0E)

The WD Black SN7100 is a line of internal solid-state drives in M.2 2280 form factor for NVMe-equipped systems, designed for gaming PCs, laptops, and portable gaming devices. The WD Black SN7100 series uses a PCIe 4.0 x4 interface, Western Digital TLC 3D NAND memory, and a DRAM-less architecture, with capacities ranging from 500 GB to 1 TB, 2 TB, and 4 TB. The WD Black SN7100 offers different speed ratings depending on capacity: the 500 GB model delivers up to 6800 MB/s read and up to 5800 MB/s write speeds, the 1 TB and 2 TB versions achieve up to 7250 MB/s read and up to 6900 MB/s write speeds, while the 4 TB model reaches up to 7000 MB/s read and up to 6700 MB/s write speeds. Random operation performance also varies by capacity: up to 760K/1200K IOPS for 500 GB, up to 1000K/1400K IOPS for 1 TB and 2 TB, and up to 900K/1350K IOPS for 4 TB. Write endurance across the series ranges from 300 TBW for 500 GB, 600 TBW for 1 TB, 1200 TBW for 2 TB, and 2400 TBW for 4 TB, which is important for sustained use under intensive workloads. The WD Black SN7100 is also compatible with lower PCIe modes, operates in a temperature range of 0–85 °C, and measures 80×22×2.38 mm with a weight of approximately 5.8 g, making it suitable for upgrading modern compact systems where high throughput, moderate power consumption, and a choice of capacities within a single product family are priorities.
