Overview
The Samsung 990 EVO Plus 4TB M.2 NVMe SSD (model MZ-V9S4T0BW) delivers a substantial leap in storage capacity and bandwidth for client PCs, creative workstations, and gaming rigs that demand fast, reliable internal storage. Fitting the standard M.2 2280 form factor, it slots cleanly into most modern desktops and laptops with an available M.2 slot. The drive supports a dual-interface design — PCIe 4.0 x4 or PCIe 5.0 x2 — both operating under the NVMe 2.0 protocol. This flexibility means the 990 EVO Plus can take advantage of next-generation PCIe 5.0 lanes where available while remaining fully backward compatible with the widely adopted PCIe 4.0 platform. A nickel-coated controller is central to the drive's efficiency story: Samsung states this design achieves 73% higher MB/s-per-Watt compared to the previous generation, allowing the drive to sustain performance with less heat and reduced power draw — a meaningful advantage for laptop users concerned about battery life and thermal throttling. Data protection and long-term reliability are backed by a 5-year limited warranty and a 2,400 TBW (terabytes written) endurance rating — a generous figure for a 4TB consumer NVMe drive. Samsung Magician software accompanies the drive, providing tools for performance optimisation, health monitoring, secure data migration, and firmware updates. Verified Specifications: - Model: MZ-V9S4T0BW - Series: 990 EVO Plus - Capacity: 4TB - Form Factor: M.2 2280 - Interface: PCIe 4.0 x4 / PCIe 5.0 x2, NVMe 2.0 - Sequential Read: Up to 7,250 MB/s - Sequential Write: Up to 6,300 MB/s - Endurance (TBW): 2,400 TB - Warranty: 5-year limited - Dimensions (W x H x D): Max 80.15 x 22.15 x 2.38 mm - Weight: Max 9.0 g - Application: Client PCs The 990 EVO Plus is compatible with systems running Intel 10th Gen, 11th Gen, and newer platforms. It is suited to users upgrading from SATA SSDs or previous-generation NVMe drives who want meaningfully higher throughput without stepping up to a full PCIe 5.0 x4 flagship drive
