Samsung 990 EVO Plus 4TB M.2 NVMe SSD (PCIe 5.0 x2 / 4.0 x4, OEM Fresh Unit)

The Samsung 990 EVO Plus 4TB is a high-capacity M.2 NVMe solid-state drive designed to meet the demands of power users, creative professionals, and anyone who needs large-scale fast storage in a compact form factor. Housed in the universally compatible M.2 2280 form factor, this drive slots directly into modern desktop motherboards, laptops, and mini-PC builds that support M.2 NVMe slots. One of the standout characteristics of the 990 EVO Plus is its dual-interface PCIe support: the drive operates over PCIe 5.0 x2 or PCIe 4.0 x4, giving it flexibility across both current-generation and recent-previous-generation platforms. This means users upgrading to new PCIe 5.0 motherboards benefit from the additional bandwidth headroom, while those on mature PCIe 4.0 systems enjoy full x4 lane utilisation without any compatibility issues. The drive employs Host Memory Buffer (HMB) technology in place of a dedicated onboard DRAM cache. HMB borrows a small portion of the system's main memory to manage mapping tables and frequently accessed data, keeping the bill-of-materials lean while maintaining responsive random-read performance for everyday workloads including operating system boot, application launch, and file access. This listing is an OEM Fresh Unit, meaning the drive ships without retail packaging but is a genuine, new, unused Samsung 990 EVO Plus — not refurbished or pulled from another system. Such OEM units are commonly sourced from system-integrator channels and are an economical route to authentic Samsung storage.
