This article covers WD 内蔵SSD M.2-2280.

Overview

Western Digital's WD Black SN750 series is designed for gamers and creative professionals who demand fast storage. The model WDS500G2X0C is a 500GB NVMe SSD using the PCIe Gen3 x4 interface, delivering sequential read speeds up to 3,400 MB/s and sequential write speeds up to 2,500 MB/s. With random read performance of 410,000 IOPS and random write of 330,000 IOPS, this drive significantly reduces boot times and application load times. Positioned as a mid-to-high-end gaming SSD, the SN750 comes with a 5-year warranty and includes a DRAM cache for consistent performance under sustained writes. It slots into the M.2 2280 form factor and is compatible with most modern motherboards that have a PCIe Gen3 or higher M.2 slot.

Compatibility Guide

The SN750 uses the M.2 2280 form factor and the NVMe 1.3 protocol. It requires a PCIe Gen3 x4 or higher M.2 slot on the motherboard. It is backward compatible with PCIe Gen2 slots but will operate at reduced speeds. Before purchase, verify that your motherboard supports NVMe (not just SATA) on the M.2 slot. Form factor: M.2 2280 (80mm length) Interface: PCIe Gen3 x4, NVMe 1.3 Supported OS: Windows 10/11, macOS, Linux (after formatting) Note: Will not work in M.2 slots that are SATA-only. Check your motherboard manual.

Product Info

The WD Black SN750 500GB (WDS500G2X0C) was released in 2019 and remains a solid choice for Gen3 builds. It uses 3D TLC NAND flash with a proprietary in-house controller and a DRAM cache. The drive is rated for 300 TBW (Total Bytes Written) and comes with a 5-year limited warranty. Pricing has dropped over time, and the 500GB model is now available for around $50–60 USD or ¥23,000 JPY in Japan. Capacity: 500GB Interface: NVMe PCIe Gen3 x4 Sequential Read: 3,400 MB/s Sequential Write: 2,500 MB/s Random Read: 410,000 IOPS Random Write: 330,000 IOPS NAND: 3D TLC DRAM Cache: Yes Endurance: 300 TBW (approx. 0.82 years assuming 1TB/day write) Warranty: 5 years

Best Use Cases

  1. Primary Gaming Drive User profile: Gamers who want fast load times for OS and frequently played titles. The SN750 excels at random reads, reducing stutter and level loading. Why it fits: High random IOPS and DRAM cache ensure smooth gameplay even during texture streaming. The 500GB capacity holds a few AAA games alongside the OS. Who should avoid: Users with large game libraries (over 1TB) should consider the 1TB version or a larger SSD. 2. Creative Work Drive User profile: Photographers and light video editors working with RAW files and 1080p/4K projects. The 3,400 MB/s read speed speeds up previews and exports. Why it fits: Fast sequential reads handle large image batches well. The 500GB capacity is sufficient for active projects. Who should avoid: Heavy 4K/8K video editors or 3D renderers need more capacity and Gen4 speed. 3. Laptop or Secondary PC Upgrade User profile: Users upgrading an older laptop or building a secondary PC. The SN750's low power draw and moderate heat make it suitable for cramped spaces. Why it fits: Gen3 SSD is power-efficient, extending battery life. Easy drop-in replacement for existing M.2 drives. * Who should avoid: Laptops with only M.2 SATA support cannot use this drive. Check compatibility first.

Things to Consider

The SN750 is a PCIe Gen3 drive. If you plan to upgrade to a Gen4 platform in the future, the drive will still work but cannot reach Gen4 speeds. Consider a Gen4 SSD if you want future-proofing. 500GB fills up quickly. After installing Windows and a few large games, you may have limited free space. Monitor your usage and consider the 1TB variant if you have a larger library. Competitors like the Samsung 970 EVO Plus and Crucial P5 offer similar performance. The WD bundle includes the SSD Dashboard utility and Acronis True Image cloning software, which can be a deciding factor. Performance numbers are theoretical maximums; real-world speeds depend on system configuration and workload. ## FAQ
Q: Can I use this SSD in a PlayStation 5? A: No. The PS5 requires a Gen4 NVMe SSD with a heatsink. This drive is Gen3 and lacks a heatsink, so it is not compatible with PS5. Q: What happens if my motherboard's M.2 slot is Gen3 x2 instead of x4? A: The drive will operate at Gen3 x2 speed, capping sequential reads around 2,000 MB/s. It will still be much faster than SATA, but you won't get the full advertised speed. Q: How long will the 300 TBW endurance last? A: For typical daily use (writing 10-20GB per day), the drive could last over 15 years. The 5-year warranty covers defects, and the TBW rating is a guideline for warranty coverage, not a hard failure limit.
