What You're Getting

The WD_Black SN8100 is a PCIe Gen 5.0x4 NVMe M.2 2280 SSD built on Sandisk's latest TLC 3D CBA NAND technology. Key specs include:

Sequential read speeds up to 14,900MB/s and write speeds up to 14,000MB/s on the 2TB-4TB models. Random performance exceeds 2,300,000 IOPS on the same capacity tiers.

Power efficiency is a standout feature the drive averages 7.5W or under, delivering over 100% more power efficiency than Sandisk's PCIe Gen 4 drives. Endurance is rated up to 4,800 TBW on the 8TB model, and the drive supports capacities up to 8TB. The Sandisk Dashboard software (Windows only) lets you monitor drive health and performance, and Acronis True Image for Sandisk is included for data migration.

Who This Is For

This is for anyone building or upgrading a high-end PC with a PCIe 5.0-compatible motherboard. Content creators working with large video files, AI model training datasets, or massive game libraries will see the most benefit from the 4TB capacity and blistering sequential speeds.

If your workflow involves moving multi-gigabyte files regularly, this drive cuts transfer times dramatically. Gamers moving from PCIe 4.0 will notice faster level loads, though the real-world gaming difference between Gen 4 and Gen 5 SSDs is still narrowing by the month.

Final Verdict

The $669.99 price sits $108 below the 30-day average and $300 below the 90-day average, making this a well-timed buy if you need 4TB of Gen 5 storage now. PCIe 5.0 drives in this capacity class rarely see cuts this deep outside of major sales windows.

If your build supports Gen 5 and you need the capacity. This is the price to act on.
