Western Digital WD_BLACK SN7100 2TB PCIe 4.0 NVMe M.2

The SN7100 hits 7,250 MB/s read and 6,900 MB/s write, landing in the 91st percentile for speed. Buyers love it, with a 4.8 rating from 6,804 reviews. Endurance is the weak spot at the 15th percentile, but for gaming and everyday use, this drive is a winner.

7,250 MB/s read and 6,900 MB/s write. Those are the numbers that matter, and they're basically maxing out the PCIe 4.0 interface. In our database, this drive's speed lands in the 91st percentile, which means it's one of the best Gen4 drives on the market right now. You're not going to find many drives that push past this without jumping to PCIe 5.0, and those cost a whole lot more.

The TLC NAND is doing the heavy lifting here, and it's a good match for the controller. Random performance sits at the 61st percentile, which is solid but not spectacular. That means everyday tasks like booting Windows or loading games will feel snappy, but if you're doing heavy database work or constant small-file writes, you'll notice the gap between this and the top-tier drives. For gaming and general use, the sequential speeds are what you'll feel most, and those are excellent.

Against the Samsung 9100 PRO, the SN7100 holds its own on sequential speeds but gives up ground on endurance and random performance. The Samsung is the more complete package if you're doing workstation-level work, but you'll pay for it. The Crucial T500 is probably the closest real competitor here, with similar Gen4 speeds and a better endurance story, though the WD_BLACK's social proof at the 95th percentile suggests buyers are happier with this one overall. The Kingston FURY Renegade G5 and Seagate FireCuda 530R both trade blows on speed, but the SN7100's 7,250 MB/s read puts it right at the front of this pack. Where the WD_BLACK really wins is that combination of top-tier sequential speed and a 4.8 rating from nearly 7,000 reviews. That's hard to argue with.

Pricing is all over the place depending on where you shop. In the US, you'll find it between USD 339 and USD 388, and that USD 49 spread means it's worth checking both listings before you buy. The lower end of that range is where this drive makes the most sense. In Europe, the gap is even wider, from EUR 361 to EUR 472 across four listings, so shopping around can save you over EUR 100. The affordability percentile sits at just 30th, which tells you this isn't a budget drive by any stretch. But when you factor in the 91st percentile speed and the 95th percentile customer satisfaction, the price starts to look more reasonable. You're paying for top-tier Gen4 performance, not just a name.

The WD_BLACK SN7100 hits 7,250 MB/s read and 6,900 MB/s write, which puts it in the 91st percentile for speed in our database. That's the headline here. For a Gen4 drive, those numbers put it right at the top of what the interface can do, and it does it with TLC NAND instead of the pricier stuff. The 2TB capacity is also a solid 78th percentile, so you're getting both speed and room to breathe.

But the story gets more interesting when you look at the full picture. Social proof is through the roof at the 95th percentile with a 4.8 rating across 6,804 reviews, which tells us buyers are genuinely happy with this thing. The catch is endurance, sitting at a rough 15th percentile. If you're planning to hammer this drive with constant writes, that's a real concern. For most people though, the speed and price combo is going to matter a lot more.

If you're doing heavy content creation, video editing, or anything that involves writing large amounts of data daily, look elsewhere. The 15th percentile endurance rating is a real limitation for write-heavy workloads, and the 61st percentile random performance won't do you any favors in database or virtualization scenarios. The portable use case score of 20.6 out of 100 also tells you this isn't the drive to throw in an external enclosure for on-the-go work. And if you're on a tight budget, the 30th percentile affordability ranking means there are cheaper Gen4 options that will get the job done, just not as fast.

The WD_BLACK SN7100 is a speed-first Gen4 drive that delivers exactly what it promises. 7,250 MB/s read and 6,900 MB/s write are numbers you can feel, and the 91st percentile speed ranking backs that up. The 4.8 rating from 6,804 reviews tells you real buyers are happy with their purchase, and that's the strongest signal we have. The endurance situation at the 15th percentile is the one thing that gives us pause, but for gaming, laptops, and everyday use, this drive is a top pick. If you're not writing terabytes of data every week, you'll likely never notice the endurance gap. For most people, this is one of the best Gen4 drives you can buy right now.
