This article covers Western Digital ウエスタンデジタル 内蔵SSD 2TB WD Black SN750 ゲーム向け M.2-2280 NVMe WDS200T3X0C-EC 【国内正規代理店品】.

Overview

Western Digital's WD Black series has long been a go-to choice for gamers and creative professionals seeking high-performance storage. The WD Black SN750 2TB (model WDS200T3X0C-EC) is an NVMe M.2-2280 internal SSD that packs 2TB of capacity onto a compact board, making it ideal for builds where space is at a premium. With sequential read speeds of up to 3,470MB/s over a PCIe Gen3.0 x4 interface, this drive significantly reduces game load times and accelerates large file transfers. It also supports WD's Gaming Mode, which keeps the drive running at peak performance under sustained workloads. Positioned as a mid-to-high-end NVMe SSD, the SN750 offers a strong balance of speed, capacity, and reliability at a competitive price point. While PCIe Gen4 drives have since emerged, the SN750 remains a solid choice for Gen3 platforms where cost-effectiveness matters.

Compatibility Guide

The WD Black SN750 uses the M.2-2280 form factor and requires an NVMe-compatible M.2 slot on your motherboard. It works seamlessly with modern platforms including Intel LGA1200/1700/1851 and AMD AM4/AM5. However, older motherboards may have M.2 slots that only support SATA mode, so check your manual before purchasing. If your motherboard includes a built-in heatsink for the M.2 slot, ensure there is enough clearance for the SSD's single-sided PCB design. The drive itself does not come with a heatsink, but it can be used with aftermarket coolers if needed.

Product Info

Released in 2019, the WD Black SN750 2TB is still widely available through major retailers. Pricing typically falls around the ¥50,000 mark, offering good value for a 2TB NVMe SSD. Western Digital backs it with a 5-year limited warranty. The drive uses 3D TLC NAND flash memory and features a DRAM cache for consistent random read/write performance. Sequential read speeds reach 3,470MB/s, while write speeds hit 3,000MB/s on the 2TB variant. These figures are more than adequate for everyday gaming, video editing, and general productivity.

Best Use Cases

Gamers building a high-capacity gaming rig will appreciate the 2TB capacity, which allows installing dozens of modern AAA titles without worrying about storage space. The NVMe speed ensures fast level loading and smooth texture streaming. Creative professionals working with large media files—such as 4K video footage, RAW photos, or complex project files—will benefit from the drive's fast sequential writes and ample capacity. It serves well as a primary working drive for editing software. Users looking to upgrade from a traditional HDD to an SSD for their system drive will find the SN750 a reliable and fast option. Boot times, application launches, and overall system responsiveness improve dramatically.

Things to Consider

The SN750 is a PCIe Gen3 drive, so if you install it in a Gen4-capable motherboard, it will operate at Gen3 speeds. For users who demand the absolute fastest sequential throughput, a Gen4 SSD like the WD Black SN850X would be a better fit. At 2TB, the price is relatively high. If your storage needs are modest, the 1TB variant offers a more budget-friendly entry point. Also, the SN750 is now a few years old; newer models like the SN770 and SN850X offer improved random performance and power efficiency. If your budget allows, consider those alternatives. Finally, ensure your motherboard has a free M.2 slot that supports NVMe. Some older boards may only have one such slot, which could be occupied by another drive.
