A $1200 discount that's hard to ignore.

WD_Black SN8100 NVMe SSD - PCIe 5.0x4 drops to $789.99 - save $1200. That's a 60% cut on a 4TB PCIe Gen 5 drive that hits read speeds up to 14,900MB/s, making it one of the biggest SSD discounts we have tracked this year. The 4TB model typically hovers around $1071 on its 90-day average and $1082 over the last 30 days, so this price sits well below both.

Get This Price

For just $789.99, down from its list price of $1989.99, this 4TB drive costs roughly $280 less than its 180-day average of $840.90. That kind of gap on a flagship Gen 5 SSD that only launched in recent months signals a genuine price reset, not a routine sale.

What You're Getting

The WD_Black SN8100 is a PCIe 5.0x4 NVMe M.2 2280 SSD built around TLC 3D CBA NAND technology. Sequential reads reach up to 14,900MB/s, writes hit up to 14,000MB/s on the 2TB and 4TB models, and random performance tops 2,300,000 IOPS.

Power efficiency is a standout -- the drive averages under 7.5W operating power, delivering over 100% more efficiency than WD's own PCIe Gen 4 drives. Endurance on the 4TB model is rated at 4,800 TBW, and the included Sandisk Dashboard (Windows) lets you monitor health and migrate data via Acronis True Image.

Who This Is For

This is for anyone building a high-end workstation or gaming rig who needs PCIe 5.0 storage without paying the early-adopter tax. Video editors moving 8K footage, AI developers loading large models, and gamers who want future-proofed load times will see immediate benefit.

If you are still on PCIe 4.0 and don't plan to upgrade your motherboard within the next year, a cheaper Gen 4 drive makes more sense.

Final Verdict

The 4TB SN8100 at $789.99 undercuts the typical Gen 5 cost-per-gigabyte by a wide margin. If you need the bandwidth and have a compatible PCIe 5.0 slot. This is the price to lock in.
