This article covers Western Digital 250GB WD Green SN350 NVMe 内蔵SSD ソリッドステートドライブ.

Overview

The Western Digital WD Green SN350 is an entry-level NVMe SSD designed for everyday computing tasks. The 250GB variant (WDS250G2G0C) delivers sequential read speeds up to 2,400 MB/s, a noticeable jump over SATA SSDs. Its compact M.2 2280 form factor fits easily into any NVMe slot on modern laptops and desktops. This drive is ideal for users who want a simple, cost-effective upgrade from a hard drive or older SATA SSD.

Compatibility Guide

This SSD uses the PCIe 3.0 x4 interface and NVMe 1.3 protocol. It is physically compatible with any M.2 2280 slot that supports NVMe – not SATA-only M.2 slots. The drive is DRAM-less and relies on Host Memory Buffer (HMB), so it works best with Windows 8.1/10/11, macOS, and Linux. No additional power cables are needed; the M.2 slot provides both power and data.

Product Info

The WD Green SN350 series is Western Digital’s budget NVMe lineup. This 250GB model (WDS250G2G0C) was released around 2022 and comes with a 3-year limited warranty. TBW (Total Bytes Written) is rated at 40 TB, which translates to roughly 11 years of light daily use (assuming 10 GB writes per day). Pricing sits around ¥13,599, making it one of the most affordable NVMe SSDs on the market.

Best Use Cases

First, it’s perfect for users upgrading from a slow HDD or an aging SATA SSD in an older PC. Everyday tasks like web browsing, office applications, and media playback will feel noticeably snappier. Second, it works well as a secondary drive for budget builds or home servers where speed is desired but capacity is less critical. Finally, it’s a great choice for very cost-constrained PC builds where every yen matters, yet you still want modern NVMe performance. ## Alternatives
Direct competitors include the Crucial P3 Plus (500GB, PCIe 4.0) and Kingston NV2 (250GB). The P3 Plus offers faster sequential speeds and a larger capacity, but at a higher price. The NV2 is similarly priced but has inconsistent NAND quality in some batches. The WD Green SN350 stands out for its steady reliability and well-known brand reputation.

Things to Consider

The 250GB capacity fills up quickly with modern operating systems and applications; if you plan to install many games or large files, consider the 500GB or 1TB versions. As a DRAM-less SSD, random write performance can suffer under heavy multitasking or large file transfers. Also, it does not support PCIe 4.0, so it won’t take advantage of the fastest available slots. For most everyday users, however, these limitations are minor.
