This article covers WD 内蔵 SSD M.2 2280.

Overview

The WD BLACK SN750 NVMe 250GB is a well-established NVMe SSD from Western Digital, designed for gamers and performance enthusiasts. It uses the M.2 2280 form factor and PCIe Gen3 x4 interface, delivering sequential read speeds up to 3,100 MB/s and write speeds up to 1,600 MB/s. With a compact 250GB capacity, it serves as an excellent boot drive or secondary storage for frequently used applications. Positioned in the entry-to-mid-range market, it offers a strong balance of performance and affordability.

Compatibility Guide

This SSD fits any M.2 slot that supports PCIe Gen3 x4 NVMe. It is compatible with most motherboards from Intel 6th-gen and AMD AM4 onward. However, older boards may lack NVMe boot support, so check your BIOS version. It is also verified to work with PlayStation 4 as an internal storage upgrade, but it is not compatible with PS5 (which requires Gen4). The single-sided M.2 2280 design ensures compatibility with most laptops and desktops.

Product Info

The WD BLACK SN750 NVMe 250GB (model WDS250G3X0C) launched in 2019 and remains widely available. It typically retails around ¥23,000 on Japan. The drive uses a WD-proprietary controller, 3D TLC NAND, and a DRAM cache for consistent performance. It comes with a 5-year warranty and supports the WD SSD Dashboard utility for monitoring and firmware updates. Market positioning is entry-to-mid-range, ideal for budget-conscious builders seeking NVMe speed.

Best Use Cases

First, it's perfect for users building a budget gaming PC who want NVMe speeds without overspending. The 250GB capacity is enough for the OS and a few key games. Second, it's a great upgrade for laptops with an M.2 slot, offering a noticeable speed boost over SATA SSDs. Third, PS4 owners can use it to reduce load times significantly, as it's officially verified for PS4 compatibility. For each scenario, the SN750's reliable performance and 5-year warranty provide peace of mind. ## Alternatives
Direct competitors include the Samsung 970 EVO Plus 250GB and Crucial P5 250GB. The Samsung offers slightly higher sequential reads (3,500 MB/s) but at a higher price. The Crucial P5 excels in random performance, while the WD BLACK SN750 stands out with its gaming-optimized firmware and robust warranty. Note that the SN750 lacks a built-in heatsink, so you may need to use your motherboard's M.2 heatsink or purchase one separately.

Things to Consider

The 250GB capacity can fill up quickly if you install many large games or media files; consider the 500GB or 1TB versions if you need more space. Since it's PCIe Gen3, you won't get Gen4 speeds even on a Gen4 motherboard, but for gaming and everyday use, Gen3 is still very capable. The price is higher than DRAM-less SSDs, but the DRAM cache ensures consistent performance under heavy workloads. Also, it's not compatible with PS5, so console gamers should look for a Gen4 drive instead.
