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.
