01 / 07WD Black SN7100 4TB NVMe PCIe Gen 4 M.2 2280 Internal SSD
The WD Black SN7100 4TB delivers sequential reads of up to 7,250 MB/s and writes of up to 6,900 MB/s over a PCIe Gen 4 x4 interface in the M.2 2280 form factor, making it the highest-capacity PCIe 4.0 drive in the SN7100 lineup. Designed for Elite and HEDT workstation builds requiring mass NVMe storage — game libraries, video production scratch volumes, and RAW photo archives — without compromising on random I/O performance (1,400K IOPS write). Compatible with AMD AM5, Intel LGA 1851, and sTR5 (Threadripper) platforms. Backed by a 5-year manufacturer warranty from Western Digital.
Features
- 7,250 MB/s Sequential Read — PCIe Gen 4 x4 bandwidth saturates the interface, enabling near-instant game load times, fast video project imports, and rapid OS boot even under heavy multitasking.
- 4TB Capacity for Elite Builds — Store 100+ AAA games, extensive RAW photo libraries, or multiple 4K/8K video projects on a single M.2 slot, freeing SATA bays or secondary M.2 slots for additional drives.
- 1,400K Random Write IOPS — High random I/O performance keeps the drive responsive during simultaneous OS operations, game streaming, and background tasks — critical in Threadripper HEDT builds running multiple parallel workloads.
- PCIe Gen 4 x4 — Broad Platform Support — Compatible with AMD AM5 (Ryzen 9000/7000), Intel LGA 1851 (Core Ultra 200S), and AMD sTR5 (Threadripper 7000) platforms without adapters or firmware patches.
- M.2 2280 Form Factor — Fits all standard M.2 slots; no additional bracket needed. Works in both ATX motherboards and compact ITX builds.
- 5-Year Warranty — Full Western Digital 5-year manufacturer warranty provides long-term peace of mind for primary storage in workstation and gaming systems.
