WD_BLACK SN8100 Gen 5 SSD Hits $700 for 4TB, 14,900MB/s Read Speeds

The WD_BLACK SN8100 brings PCIe NVMe Gen 5 speeds to the mainstream market, offering a significant jump in data throughput for users who need fast storage. This drive matters because it delivers near-peak generation 5 performance in a standard 2280 form factor that fits most modern desktops and laptops. We can now buy this high-speed storage without needing a specialized expansion card or a massive chassis.

Mainstream Gen 5 storage arrives with 14,900MB/s speeds and 7.5W power draw

WD_BLACK built the SN8100 around TLC 3D CBA NAND to handle the heavy lifting of next-generation data transfer. The controller and memory work together to push sequential read speeds up to 14,900MB/s and write speeds to 14,000MB/s. These numbers make the drive one of the fastest consumer storage options available right now for large file transfers.

Specifications

• Interface: PCIe NVMe Gen 5
• Sequential Read Speed: 14,900MB/s
• Sequential Write Speed: 14,000MB/s
• Random IOPS: 2.3 million
• Endurance (TBW): 2,400TBW

Power efficiency remains a key focus for this generation of SSDs, and WD_BLACK claims the SN8100 uses 100 percent greater power efficiency compared to PCIe NVMe Gen 4 drives. The 4TB model draws just 7.5W during operation, which helps keep system temperatures and power bills in check. The drive also offers a 2.3 million IOPS rating for random access tasks, ensuring snappy performance for operating systems and applications.
