SanDisk 1TB SSD PCIe 4.0 NVMe

The WD_BLACK SN850X is a top-tier Gen4 SSD with 7,300 MB/s reads and excellent random performance. It's not the cheapest option, but 17,000+ reviews at 4.8 stars say it's worth it. Buy it if you want a fast, reliable gaming drive without any drama.

The SN850X is fast. Really fast. 7,300 MB/s sequential reads put it in the 86th percentile for speed, which translates to near-instant level loads and snappy texture streaming. Random performance is where it really shines though, 800K read IOPS and 1.1M write IOPS land it in the 93rd percentile. That's the stuff that makes Windows feel responsive and keeps open-world games from hitching. The TLC NAND and DRAM cache combo means sustained writes don't fall off a cliff either. One owner benchmarked 7,133 MB/s reads in performance mode, which is basically hitting the spec sheet. The 600 TBW endurance rating is solid for a 1TB drive, though not class-leading.

The Samsung 990 PRO is the obvious rival here, and it's a close fight. The 990 PRO edges out the SN850X in some synthetic benchmarks, but in real-world gaming you'd be hard pressed to tell them apart. The Crucial T500 is another strong Gen4 option that often undercuts both on price. The Kingston Fury Renegade matches the SN850X's speed but runs hotter without a heatsink. The Micron T710 and Lexar NM1090 PRO are newer entries that push Gen4 limits further, but they don't have the same track record. The SN850X's real advantage is that it's been around long enough to prove itself, 17,000 reviews don't lie.

Pricing is all over the place depending on where you shop. In the US you're looking at $230 to $247, which is reasonable for this level of performance. But in Europe the spread is wild, EUR 212 to EUR 300 across four listings. That's an EUR 88 gap for the exact same drive. If you're in the EU, shop around before you click buy. The Canadian spread is even worse at CAD 288 to CAD 380. Our database puts affordability at the 43rd percentile, so it's not a budget pick. But for the speed and reliability you're getting, the lower end of those price ranges feels fair.

The WD_BLACK SN850X is one of those drives that just gets out of the way and lets your games load. We're looking at 7,300 MB/s reads and 6,300 MB/s writes on paper, and real-world benchmarks from owners back that up. It's a Gen4 drive that still hangs with the best of them, even as Gen5 stuff starts trickling out. The optional heatsink version is a nice touch if your motherboard doesn't have its own M.2 cooling.

Our database puts this thing in the 95th percentile for social proof and 94th for features. That's not marketing fluff, that's 17,000+ reviews averaging 4.8 stars. People genuinely like this drive. The 1TB capacity is middle of the pack these days, but for a boot drive plus a few big games, it's plenty.

If you're on a tight budget, look elsewhere. The SN850X sits in the 43rd percentile for affordability, and there are cheaper Gen4 drives that get you 90% of the performance for less money. If you need massive capacity in a single drive, the 1TB version won't cut it either. And if you're planning to use this in a portable enclosure, our data shows portable performance is a weak spot at 21.8/100, so you'd be better off with something designed for that use case.

If you're building a gaming PC or upgrading an existing one, the SN850X is an easy recommendation. It's fast enough that you won't be thinking about your storage, which is exactly what you want. The 1TB version makes sense as a boot drive paired with a bigger secondary drive for your game library. The heatsink version is worth the small premium if your board lacks M.2 cooling. This is a drive that just works, and works fast.
