Product overview

The Western Digital WD_BLACK SN7100 1TB is a high-performance NVMe SSD designed for gaming PCs, laptops, and handheld consoles. Built on the proprietary Polaris 3 controller and Kioxia 218-layer TLC 3D NAND, it delivers sequential read speeds of 7,250 MB/s and write speeds of 6,900 MB/s, representing a 35% performance improvement over the previous SN770 generation. The drive features 1,000K random read IOPS and 1,400K random write IOPS with 600 TBW endurance rating. Its single-sided M.2 2280 form factor (80mm × 22mm × 2.38mm, 5.8g) makes it ideal for space-constrained devices. The DRAM-less architecture uses Host Memory Buffer technology for efficiency. Operating temperature range is 0–85°C, with backward compatibility across PCIe Gen2/Gen3/Gen4 interfaces. Windows 10+ compatible with 5-year limited warranty.

Frequently asked questions

What are the performance specifications for the WD_BLACK SN7100 1TB?

The 1TB model delivers 7,250 MB/s sequential read and 6,900 MB/s sequential write speeds. Random performance reaches 1,000K IOPS for reads and 1,400K IOPS for writes. These specifications represent a 35% performance improvement over the previous WD_BLACK SN770 generation, making it suitable for gaming and AI workloads.

Is this drive compatible with older systems?

Yes. The WD_BLACK SN7100 is backward compatible with PCIe Gen2, Gen3, and Gen4 interfaces across all lane configurations (x1, x2, x4). It supports Windows 10 and later operating systems, enabling deployment across legacy and modern platforms without compatibility concerns.

What is the endurance rating and warranty?

The 1TB model is rated for 600 TBW (Terabytes Written) endurance, supporting 3–5 years of intensive use. Western Digital provides a 5-year limited warranty covering manufacturing defects and hardware failures, ensuring long-term reliability for enterprise and consumer deployments.

Why is the single-sided design important?

The single-sided M.2 2280 layout (80mm × 22mm × 2.38mm, 5.8g) eliminates dual-sided thermal management requirements, enabling integration into thin laptops and handheld gaming consoles. This design reduces manufacturing complexity and cooling costs while maintaining full performance.

What makes this drive suitable for gaming?

The 7,250 MB/s read speed dramatically reduces game loading times. The 1,400K random write IOPS supports rapid asset streaming and shader compilation. 100% improved power efficiency extends battery life in portable gaming devices, while the 35% performance boost handles next-generation game requirements.

Does this drive require a separate DRAM cache?

No. The WD_BLACK SN7100 uses a DRAM-less architecture with Host Memory Buffer (HMB) technology, which allocates system RAM as cache. This reduces manufacturing costs and power consumption while maintaining performance, making it ideal for cost-sensitive bulk procurement.

What are the operating temperature specifications?

Operating temperature range is 0–85°C, with storage capability from -40–85°C. This wide temperature tolerance supports global deployment across diverse climates and data center environments without thermal throttling concerns.
