Kingston NV3 4TB PCIe 4.0 x4 NVMe M.2 2280

The Kingston NV3 SNV3S/4000G packs 4TB into a single-sided M.2 2280 with 6000 MB/s reads, landing in the 93rd percentile for capacity. But the 14th percentile affordability ranking means you're paying a premium for a DRAM-less drive with average random performance. Shop the price spread carefully, $579 is the best US deal and CAD 810 at Memory Express is the Canadian sweet spot.

Sequential reads at 6000 MB/s put this drive in the 78th percentile for speed. That's well above average, but it's not the absolute best right now. Drives like the Samsung 9100 PRO and WD Black SN850X push past 7000 MB/s, so the NV3 gives up a bit of headroom. The 5000 MB/s write speed is respectable, though the DRAM-less controller means you'll see dips during large sustained transfers. One reviewer compared it to a Samsung 980 Pro and saw dramatically slower transfer times in an external enclosure, though that's not a perfect apples-to-apples test.

Random performance sits at the 62nd percentile, which is about average. For everyday tasks like booting Windows, loading games, and moving files around, you won't notice much difference. But if you're doing heavy video editing or database work, the lack of DRAM and mid-pack random scores will show up. The single-sided M.2 2280 design is a plus for thin laptops and console installs, and the 2,000,000 hour MTBF is a nice reliability number on paper.

Against the Samsung 9100 PRO, the NV3 gives up a lot of speed. The 9100 PRO is one of the fastest PCIe 4.0 drives we've tested, while the NV3 sits in the 78th percentile for speed. The WD Black SN850X also beats it on both sequential and random performance, and it includes DRAM. The Crucial T500 is a closer match on price but still edges ahead on random performance. Where the NV3 wins is capacity per dollar at the 4TB tier, but even that is undercut by the Seagate FireCuda 530R in some markets. If you're buying for a laptop or console, the single-sided design is a genuine advantage over double-sided competitors like the Lexar NM1090 PRO.

This is where the NV3 gets tricky. The affordability ranking is 14th percentile, which means you're paying a premium for the Kingston name and the 4TB capacity. US prices range from $579 to $660 across four listings, a spread of $81. That's a meaningful gap, and the cheapest option at $579 is the one to hunt for. In Canada, the spread is even wider at CAD 810 to CAD 990, a CAD 180 difference. Memory Express has the best Canadian price at CAD 810. For a DRAM-less drive with mid-pack random performance, the price per gigabyte is hard to justify when faster drives with DRAM are available in the same range.

The Kingston NV3 SNV3S/4000G is a 4TB M.2 2280 PCIe 4.0 drive that hits 6000 MB/s read and 5000 MB/s write. That capacity lands in the 93rd percentile of our database, which is the real story here. You're getting a huge slab of storage in a single-sided stick that fits laptops, desktops, and even a PS5 without much fuss. The endurance rating of 1280 TBW is solid, middle of the pack, and the 3-year warranty is fine but not generous.

But the affordability ranking is rough. It sits in the 14th percentile, meaning this drive is priced near the bottom of the value barrel compared to other 4TB PCIe 4.0 options. The speed is strong but not chart-topping, and the DRAM-less design means sustained writes can dip. If you need capacity first and speed second, this works. If you want the fastest 4TB drive for the money, keep reading.

Skip this drive if you're doing heavy sustained writes or workstation workloads. The DRAM-less design and 62nd percentile random performance mean large file transfers and database operations will feel sluggish compared to DRAM-equipped alternatives. Also skip it if you're price-sensitive, the 14th percentile affordability ranking means you're paying more for less performance than the WD Black SN850X or Crucial T500 offer. And if you need a drive for portable use, the 22/100 portable score is a clear signal to look elsewhere.

The Kingston NV3 SNV3S/4000G is a capacity play first and a performance play second. The 4TB size in a single-sided M.2 2280 is genuinely useful, and the 6000 MB/s read speed is nothing to sneeze at. But the 14th percentile affordability ranking stings, especially when faster DRAM-equipped drives are available for similar money. If you need maximum storage in a thin laptop or console and you find it at the low end of the price range, it's a reasonable buy. Otherwise, the WD Black SN850X or Crucial T500 will give you better all-around performance for your dollar.
