Looking Beyond the WD_BLACK SN770 2TB Gen4 NVMe SSD? 6 Alternatives Worth a Look

How each alternative compares

WD_BLACK SN850 2TB Gen4 NVMe SSD

The WD_BLACK SN850 shares the same M.2 2280 form factor and 2TB capacity as the SN770, but it targets users seeking higher peak performance. While the SN770 tops out at 5,150 MB/s read speeds, the SN850 delivers faster sequential transfers, making it better for heavy gaming loads. It uses 3D NAND technology, which may offer different endurance characteristics compared to the SN770. You should choose this if your motherboard supports full Gen4 bandwidth and you want to minimize load times further. It lacks the built-in heatsink of premium models, so you must ensure your system has adequate airflow to maintain those higher speeds during sustained writes.

WD_BLACK SN850X 2TB NVMe SSD with Heatsink

The WD_BLACK SN850X with Heatsink offers a significant physical difference by including a built-in thermal solution. This heatsink increases the drive's height to 1 inch and length to 5 inches, which may interfere with low-profile cases or GPU clearance. Performance-wise, it exceeds the SN770’s 5,150 MB/s read speed, providing faster data access for creators and gamers. If you build a desktop where airflow is restricted or you want to simplify installation by avoiding separate thermal pads, this model is preferable. It sacrifices compactness for thermal management and higher sustained performance, making it a better fit for power users than those with tight space constraints.

Samsung 980 PRO 2TB PCIe 4.0 NVMe SSD

The Samsung 980 PRO distinguishes itself with sequential read speeds reaching 7,000 MB/s, significantly outpacing the SN770’s 5,150 MB/s. It maintains the standard M.2 2280 form factor, ensuring compatibility with most modern motherboards. However, it does not include a heatsink, requiring you to manage thermal output independently. The 980 PRO is ideal for users who prioritize maximum sequential throughput for large file transfers or high-end gaming. It offers a different controller architecture that may behave differently under heavy sustained loads compared to the SN770. If your workflow involves frequent large data movements, the Samsung drive provides a clear speed advantage over the Western Digital option.

Sandisk WD_Black SN7100 2TB Gen4 SSD

The WD_BLACK SN7100 is optimized for laptop and handheld gaming devices, focusing on efficiency alongside Gen4 performance. It shares the 2TB capacity and M.2 2280 shape with the SN770 but targets portable systems where power consumption and thermal density matter more than absolute peak speeds. It uses TLC NAND, which can offer better endurance in write-heavy scenarios compared to some QLC alternatives. If you are upgrading a laptop or a Steam Deck-style device, this drive may provide better thermal efficiency and battery life impact than the desktop-oriented SN770. It is a practical choice for mobile gaming builds where space and heat are primary concerns.

SanDisk 2TB PCIe 5.0 NVMe SSD

The SanDisk 2TB PCIe 5.0 SSD represents a generational leap with its interface, moving beyond the Gen4 standard used by the SN770. It requires a motherboard with PCIe 5.0 support to function, limiting compatibility with older systems. This drive offers extreme sequential bandwidth, far exceeding the SN770’s capabilities, making it suitable for professionals handling massive datasets or future-proofing a high-end build. It retains the standard M.2 2280 footprint, ensuring easy installation in compatible slots. However, if your current system is Gen4 only, this drive will not run at its full potential. It is the right choice only if you have the necessary hardware to support the newer interface.

Western Digital 2TB WD Green SN3000 M.2 SSD

The Western Digital WD Green SN3000 provides 2TB of storage with sequential read speeds up to 5,000 MB/s, which is slightly lower than the SN770’s 5,150 MB/s. It is positioned as a budget-friendly option for gamers who do not need top-tier write performance. The drive shares the M.2 2280 form factor, ensuring broad compatibility. It offers a practical solution for users who prioritize capacity and cost over maximum speed. If your gaming library is large but you do not engage in heavy content creation or sustained large file writes, the SN3000 is a sensible alternative. It gives up some peak performance for a more accessible price point, making it suitable for standard storage needs.
