This article covers Samsung (サムスン) 内蔵SSD 990 EVO Plus NVMe 2.0 PCIe 4.0 x 4.

Overview

The Samsung 990 EVO Plus is an internal M.2 SSD that supports NVMe 2.0 and delivers sequential read speeds up to 7,250 MB/s and write speeds up to 6,300 MB/s. It features a flexible interface compatible with both PCIe 4.0 x4 and PCIe 5.0 x2, making it a versatile storage solution for current and next-generation platforms. With a massive 4TB capacity and approximately 73% improved energy efficiency over its predecessor, this drive is ideal for gaming, content creation, and everyday computing. Samsung's proprietary controller and V-NAND technology ensure consistent performance and reliability. The drive supports hardware-based encryption, adding a layer of security for sensitive data. Whether you're loading AAA games, editing 4K video, or running virtual machines, the 990 EVO Plus offers a balanced blend of speed, capacity, and power efficiency.

Compatibility Guide

The 990 EVO Plus uses the standard M.2 2280 form factor and fits into any M.2 slot on desktops, laptops, and even the PlayStation 5 (requires PCIe 4.0). It operates at PCIe 4.0 x4 or PCIe 5.0 x2 depending on the host system's capabilities. When installed in a PCIe 5.0 slot, it negotiates a x2 link, which provides slightly less bandwidth than PCIe 4.0 x4, but real-world differences are minimal for most users. NVMe 2.0 compliance means native support across Windows 11/10, macOS, and Linux without additional drivers. For best performance, pair it with a motherboard that supports PCIe 4.0 or 5.0. The drive can also be used in PCIe 3.0 slots, but speed will be capped at around 3,500 MB/s.

Product Info

The Samsung 990 EVO Plus (model MZ-V9S4T0BW) was released in 2024 and sits in the mid-to-high-end SSD market. It comes with a 5-year limited warranty or until the TBW limit is reached. Samsung Magician software provides health monitoring and firmware updates. Market positioning emphasizes a balance of high sequential speeds, large capacity, and energy efficiency, making it a practical upgrade for users who don't need the absolute peak of PCIe 5.0 x4 but want great performance now with future compatibility.

Best Use Cases

Gamers: Experience faster load times in open-world and large AAA titles. The 4TB capacity lets you store dozens of games without worrying about space. Content Creators: Speed up video exports, 3D rendering, and batch photo editing. The high read/write throughput reduces waiting time during file transfers and project saves. * Power-conscious users: The improved energy efficiency benefits laptop battery life and helps keep desktop builds cooler and quieter.

Things to Consider

The 990 EVO Plus is DRAM-less and uses HMB (Host Memory Buffer), which performs well in most real-world scenarios but may lag behind DRAM-equipped drives under heavy random workloads. For maximum PCIe 5.0 x2 performance, you need a compatible motherboard and CPU; otherwise, the drive operates at PCIe 4.0 x4 or slower. Its TBW rating of 2,400 TB offers about 6.6 years of use at 1 TB of writes per day, but typical home users will see even longer lifespan. Competitors include the Samsung 990 Pro (with DRAM, PCIe 4.0 x4 only) and Crucial T700 (PCIe 5.0 x4). If you prioritize capacity and value over extreme random I/O, the 990 EVO Plus is an excellent choice.
