The SN850P Just Became the Least-Bad SSD Buy

Woot has knocked the WD Black SN850P down to $189.99 for 1TB, $299.99 for 2TB, and $549.99 for 4TB, according to Tom's Hardware. In normal times I would not get excited about a PCIe 4.0 gaming SSD deal in 2026, but these are not normal times: NAND pricing has stopped behaving like gravity exists, and the cheap 4TB upgrade path is quietly disappearing.

This Is Really an SN850X in a PlayStation Jacket

The important bit: the SN850P is basically the WD Black SN850X with official PlayStation 5 licensing and a heatsink. That means PCIe 4.0 x4, WD's in-house controller, DRAM cache, 112-layer BiCS5 TLC NAND, and rated sequential performance up to 7,300 MB/s reads and 6,600 MB/s writes. It is not exotic Gen 5 silicon, but it is fast enough for real gaming workloads, DirectStorage-style read bursts, PS5 expansion duty, and desktop scratch-space use without requiring a tiny fan screaming under your GPU.

4TB Is the One That Matters

WD Black SN850P Woot Pricing by Capacity

The 1TB model has the biggest advertised discount, but the 4TB drive is the one data hoarders should care about. At $549.99, it works out to about $137.50 per TB, versus $150 per TB for the 2TB and $190 per TB for the 1TB. Capacity is the only SSD spec you cannot firmware-update later, and modern game installs, camera dumps, local AI models, and VM images eat NAND like raccoons in a server room.

Endurance Is Boring Until It Saves You

WD rates the SN850X/SN850P family at 600TBW per TB of capacity, so the 4TB model lands at 2,400TBW with a five-year warranty. That is a sensible endurance curve for TLC NAND and far healthier than the increasingly common high-capacity QLC tradeoff. Still, do not confuse endurance with invincibility: controller death, firmware bugs, filesystem corruption, theft, fire, and human stupidity are all faster than wear leveling. No RAID is a substitute for backups.

Why This Deal Feels Like a Warning

Tom's Hardware notes that storage prices are holding or rising, and that is the real story. AI infrastructure is absorbing memory and NAND supply, OEMs are fighting for allocation, and consumer SSD pricing is no longer drifting downward by default. If you need a PS5 or PC upgrade, especially at 4TB, this kind of TLC-with-DRAM drive is exactly the tier I would buy before settling for a mystery-controller bargain bin special.

WD Black SN850P Cost per Terabyte

Data Hoarder Verdict

I would still keep a proper 3-2-1 backup plan before trusting any single M.2 stick with irreplaceable data, but as a hot game library, workstation scratch disk, or PS5 expansion drive, the SN850P deal is unusually practical. The heatsink is useful, the performance is proven, the endurance rating is honest, and the 4TB pricing is the least offensive number on the page. In 2026 SSD shopping, that counts as a win.
