Western Digital Black AN1500 4TB NVMe Gen3 SSD (Add In Card)

The Western Digital Black AN1500 4TB NVMe Add-In Card (AIC) is a purpose-built storage solution for desktop systems that demand both massive capacity and rapid NVMe throughput in a single expansion slot. Unlike conventional M.2 drives, the AN1500 ships as a full-length PCIe Add-In Card — a form factor that allows Western Digital to combine NVMe flash modules behind a PCIe Gen 3 x8 interface, delivering sequential read speeds of up to 6,500 MB/s as specified by the source data. With 4TB of usable storage, the AN1500 is aimed at content creators, video editors, 3D artists, and power users who work with large project files and cannot afford the latency or fragmentation that comes from juggling multiple smaller drives. The AIC form factor slots directly into a standard PCIe x8 or x16 lane on a desktop motherboard, so no M.2 slot is consumed and the drive benefits from direct-to-CPU bandwidth on platforms that support it. The Western Digital Black product line is positioned as the company's performance tier for personal computing, and the AN1500 carries the WD Black branding alongside its focus on sustained workloads.
