This article covers Samsung (サムスン) 内蔵SSD 990 Evo Plus NVMe M.2 PCIe 4.0 x 4.

Overview

The Samsung 990 Evo Plus MZ-V9S1T0BW is a high-performance NVMe M.2 internal SSD from Samsung. It delivers sequential read speeds of up to 7,150MB/s and supports both PCIe 4.0 x4 and PCIe 5.0 x2 interfaces, offering flexibility for modern systems. With a 1TB capacity, it is ideal for reducing game load times and accelerating file transfers. The Intelligent Turbo Write 2.0 technology enhances write performance, making it suitable for creative workloads and everyday computing. Positioned in the mid-high range, it offers excellent value for its price.

Compatibility Guide

This SSD uses the M.2 2280 form factor and fits into any standard M.2 slot on desktops and laptops. It operates over PCIe 4.0 x4 or PCIe 5.0 x2, and is backward compatible with PCIe 3.0 slots (with reduced speed). No additional power cables are required; power is supplied through the M.2 slot. It works with Windows, macOS, and Linux, and can be managed using Samsung Magician software.

Product Info

Released in 2024, the Samsung 990 Evo Plus is a relatively new addition to Samsung's SSD lineup. The 1TB model is priced around ¥48,000, offering a balanced mix of performance and affordability. It comes with a 5-year warranty (or until TBW is reached). Available through major retailers and online stores, including and Samsung's official website. It occupies the mid-high tier in the market, standing out for its PCIe 5.0 support at a competitive price point.

Best Use Cases

Gamers: Ideal for reducing load times in modern games, especially those utilizing DirectStorage technology. Creators: Excellent for video editing, 3D rendering, and other tasks involving large file transfers, thanks to its high read speed. * System Upgraders: A great choice for users upgrading from SATA SSDs or HDDs, providing a noticeable boost in system responsiveness. Recommended for those with PCIe 4.0 motherboards.

Things to Consider

This SSD uses HMB (Host Memory Buffer) instead of a dedicated DRAM cache, which may lead to performance drops under sustained heavy write workloads compared to DRAM-equipped models. When connected via PCIe 5.0 x2, the bandwidth is equivalent to PCIe 4.0 x4, so users seeking full PCIe 5.0 bandwidth should consider alternative drives. The TBW rating is 600TB, which is sufficient for typical use but may be a concern for heavy writers. It is not recommended for server or enterprise environments.
