The Western Digital Black SN7100 Gen 4 M.2 2280 NVMe SSD is built for users who want fast storage that keeps up with demanding workloads. With a 1TB capacity, it’s well-suited for storing large game libraries, high-resolution media, and professional applications without constantly juggling installs or managing limited space. Whether you’re upgrading a gaming PC, a creator workstation, or a compatible laptop, this NVMe drive is designed to deliver responsive performance and smooth multitasking.
Equipped with a PCIe Gen4 x4 interface, the SN7100 targets high sequential throughput to reduce wait times. It supports up to 7,250MB/s sequential read speeds and up to 6,900MB/s sequential write speeds, helping applications launch quickly and improving the speed of large file transfers. This makes it a strong choice for gamers who want faster level loading, and for content creators who frequently move or render large assets.
Beyond sequential speed, the SN7100 is also optimized for random performance, which is critical for real-world responsiveness. The drive is rated at up to 1,000K IOPS for reads and up to 1,400K IOPS for writes, supporting quick access to many small files. That behavior is especially beneficial in competitive gaming scenarios, where frequent asset streaming and rapid system responsiveness matter, as well as in video editing and other intensive workflows that rely on fast storage access patterns.
The SN7100 uses TLC 3D NAND technology, combining high-density storage with strong performance characteristics. It also carries a 600 TBW (Terabytes Written) endurance rating, which helps ensure the SSD can handle heavy usage over time. For added peace of mind, it comes with a 5-year limited warranty, making it a practical option for users planning a long-term system upgrade.
The drive is designed to operate efficiently across a temperature range of 0°C to 85°C, supporting stable performance under typical high-load conditions. It features a DRAM-less architecture with up to 100% improved power efficiency compared to its predecessor, which can be particularly helpful in portable systems where energy efficiency contributes to better battery life and overall system thermals.
With Western Digital’s WD_BLACK Dashboard for Windows, users can monitor drive health and activate Game Mode for peak performance. This can be useful for maintaining confidence in your storage condition and for optimizing performance during gaming sessions, especially when you want consistent responsiveness.
