Users who want the fastest 1TB to 4TB PCIe 4.0 SSD that won’t break the bank, will want the WD Black SN7100, which is still available under that name but will be sold as the SanDisk Optimux GX 7100 going forward. (SanDisk was acquired, then recently divested by WD.) We were wowed by the 2TB version’s first-place finish among host memory buffer (HMB/DRAM-less) SSDs in our benchmarks.Read G
With Gen 5 drives like the Samsung 9100 Pro SSD out in the market, we're at a point where we're reaching the pinnacle of what Gen 4 drives can achieve, and the SN7100 isn't necessarily trying to reach the peak of the mountain with its 7,084.27 and 6858.23 MB/s average read and write speeds.Read

For most users, I'd recommend the WD BLACK SN7100 . It consistently outperforms the Samsung in real-world applications and runs remarkably cool while doing so.

While it's not one of the fastest SSDs on the market in 2026, it's worth mentioning if you are still on a Gen4 system (or as a budget option ), as it's surprisingly close to the Samsung 990 PRO in real workloads. What the SN7100 also does well is run cool, draw minimal power, and cost less than the Samsung.Read R
Still, sustained rights over longer sessions did generate noticeable heat. Nothing catastrophic, but you'll definitely want good air flow or a thermal pad for long-term stability in tight cases. Let's talk pros. Top tier sequential read and write speeds put it comfortably in the upper echelon of Gen 4 drives.Watch T
Another reason is that you have the Black SN7100 with TLC flash at a very good price. We gave that drive a 3/5 because its performance was frankly last-gen, but in lieu of the price trends that came after – with QLC flash especially being less competitive – you could put it above the P310 and Blue SN5100.Read R
However, while the drive performed admirably in all these areas, the price tag may make some gamers think twice, especially when compared to other similar options in the market.Watch T
It's no secret that it isn't the fastest or cheapest drive in its class, but it's highly efficient. Part of the reason we initially critiqued it was due to the lack of a 4TB option, but that has since changed.Read T
The main drawbacks are the absence of DRAM and a bundled heat sink, which could matter to those with specific performance needs or less than ideal cooling setups. Still, for gamers and everyday users looking for strong performance at a fair price point, the WD Black SN7100 offers impressive speed, reliability, and value.Watch P
However, it's worth noting that while the speeds are impressive, they're not the absolute fastest in the Gen 4 category. Some competitors like the Samsung 980 Pro or Sabrant Rocket 4 Plus offer slightly higher peak performance, but for most users, the difference will be negligible in practical use.Watch
