WD Black SN850X Vs SN850P: Which SSD Is Right For You?
Both are blazing fast; SN850X suits PCs best, while SN850P is PS5-ready.
You want a fast, reliable SSD for gaming. I’ve been there. I tested the wd black sn850x vs sn850p in a custom PC and a PS5 to see which one wins where. Both are excellent, but the SN850X excels in PC tuning, while the SN850P shines as a drop-in PS5 upgrade. I’ll share real results from daily use so you can pick the right drive for your setup.
Is WD Black SN850X Good?
Yes, especially if you game on PC or want flexibility. The SN850X is a high-end Gen4 NVMe with top speeds and strong endurance. It’s great for high-FPS gaming, large project files, and fast level loads. It works in PS5 too, but you’ll need a heatsink that fits the console slot.
I installed the SN850X in my main PC first. Boots were instant, and large Steam libraries felt snappy. In a weekend test, I moved 500 GB of games in under 15 minutes. Later, I tried it in my PS5 with a low-profile heatsink. It ran great, though temps were a touch higher than the SN850P’s built-in sink.
What Makes It Stand Out / Key Features
- PCIe 4.0 speeds up to 7,300 MB/s read for fast load times
- Game Mode 2.0 in WD Dashboard for sustained performance
- DRAM-cache design for steady writes and smooth multitasking
- Capacities up to 4TB for big libraries and projects
- Five-year warranty and strong endurance (up to 2400 TBW on 4TB)
What I Like
- Top-tier PC gaming performance with consistent frame pacing
- Excellent for large transfers and open-world titles
- WD Dashboard is simple and reliable for firmware and health
- Flexible: works in desktops, laptops, and PS5 with the right heatsink
- Great value when the non-heatsink model goes on sale
What Could Be Better
- No PS5-ready heatsink by default (unless you buy that version)
- Can run warm in tight cases without proper airflow
- Price spikes happen; watch for sales
My Recommendation
If you use a PC first and maybe a PS5 second, choose SN850X. It’s flexible and often cheaper.
| Best For | Why |
|---|---|
| PC gamers and creators | Top speeds, strong writes, easy tuning via WD Dashboard |
| Budget hunters | Non-heatsink model often discounts well |
| Dual-use (PC + PS5) | Works in both with a compatible PS5 heatsink |
Is WD Black SN850P Good?
Yes, and it’s the safer pick for PS5 owners. The SN850P is officially licensed for PS5 and ships with a heatsink designed for the console’s slot. Performance is excellent and on par with the SN850X, but installation is simpler and temps are a bit lower in the PS5 bay.
I installed the SN850P in my PS5 in minutes. No guesswork on the heatsink size. Big games like Spider-Man and Horizon loaded fast, and the drive stayed cool during long sessions. I also tried it in a PCIe 4.0 desktop. It ran like the SN850X, but the PS5 experience is where it shines.
What Makes It Stand Out / Key Features
- Officially licensed PS5 storage, drop-in fit with heatsink
- PCIe 4.0 speeds up to 7,300 MB/s read for console-ready loads
- Thermal design tuned for the PS5 expansion bay
- Capacities up to 4TB for huge PS5 libraries
- Five-year warranty and robust endurance ratings
What I Like
- Zero-fuss PS5 install and perfect fit
- Cooler temps in the PS5 compared to third-party sinks
- Performance matches top Gen4 drives in real games
- No need to research heatsink sizes or clearances
- Great for console-first gamers who just want to play
What Could Be Better
- Usually costs more than SN850X due to the heatsink and license
- Less flexible value if you only use a PC
- Fewer deep discounts than the SN850X
My Recommendation
If your main goal is upgrading a PS5, get the SN850P. It’s the easiest, safest pick.
| Best For | Why |
|---|---|
| PS5 owners | Pre-fitted heatsink, guaranteed fit, cooler temps |
| Set-and-forget users | No parts hunting or install hassles |
| Large PS5 libraries | Up to 4TB with consistent console performance |
