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

The Kingston NV3 4TB packs a 93rd percentile capacity into a single-sided M.2 2280 stick, which is rare and genuinely useful for laptops. Sequential speeds of 6000 MB/s read and 5000 MB/s write are well above average at 77th percentile. But affordability is a brutal 15th percentile, and the DRAM-less design keeps random performance at just 61st percentile.

The sequential numbers are respectable: 6000 MB/s read and 5000 MB/s write. That's 77th percentile for speed, which translates to well above average but not leading the pack. For context, the WD Black SN850X and Samsung 9100 PRO both push higher sequential reads, so if you're chasing benchmark bragging rights, this isn't your drive. The DRAM-less controller is the main reason random performance lands at 61st percentile, which is about average. You'll notice it in heavy multitasking or sustained small-file operations, but for game loads and large file transfers, the NV3 holds its own.

One customer reported a file transfer taking over an hour compared to three minutes on a Samsung 980 Pro, but that was before an RMA replacement, and the updated review says the new drive works great with very fast transfers. We'd chalk that up to a defective unit rather than a design flaw. The single-sided M.2 2280 form factor is a genuine advantage for laptops and thin devices where double-sided drives simply won't fit.

Against the WD Black SN850X, the NV3 gives up meaningful sequential speed and random performance. The SN850X has a DRAM cache and pushes higher reads, making it the better pick for enthusiasts. The Samsung 9100 PRO is in a different league entirely, with PCIe 5.0 speeds that embarrass this drive, though you'll pay accordingly. The Crucial T500 splits the difference, offering better random performance at a similar price point. Where the NV3 wins is capacity per dollar in a single-sided form factor. The Seagate FireCuda 530R and SanDisk WD_BLACK both offer 4TB options, but they're double-sided and often pricier. If your laptop can only take single-sided M.2 drives, the NV3's 4TB capacity at 93rd percentile becomes a genuine differentiator.

Value is where this drive stumbles. Affordability sits at 15th percentile, which is one of the worst showings in our database for this category. US pricing spans USD 579 to USD 660 across four listings, a USD 81 spread that's worth shopping around for. Newegg currently has the lowest US price at USD 579. Canadian buyers face an even wider gap, with prices ranging from CAD 810 to CAD 990, a CAD 180 difference. Memory Express has the best CAD deal at CAD 810. You're paying for the 4TB capacity and single-sided design, not raw speed, so make sure you actually need that much storage in a compact form factor before pulling the trigger.

The Kingston NV3 4TB lands in our database with a 93rd percentile capacity ranking, which is the headline here. You're getting 4TB of TLC NAND in a single-sided M.2 2280 stick, and that's a big deal for laptops and cramped builds. The 6000 MB/s read and 5000 MB/s write numbers put it at 77th percentile for speed, which is solid but not chart-topping for PCIe 4.0. The 1280 TBW endurance rating also sits at 77th percentile, so the drive should hold up for years of heavy use.

But here's the catch: affordability is at 15th percentile. That's rough. You're paying a premium for the 4TB capacity in a compact form factor, and the DRAM-less design means you're not getting the absolute best random performance either. Random sits at 61st percentile, which is fine for everyday use but not what you'd pick for heavy sustained workloads. The 4.7-star rating from 98 reviews suggests most buyers are happy, though a few horror stories about slow transfers and shipping scams are worth knowing about.

Skip this drive if you're building a high-end desktop where raw speed matters more than capacity. The 61st percentile random performance and 77th percentile sequential speed won't impress anyone coming from a WD Black SN850X or Samsung 9100 PRO. The 15th percentile affordability also makes this a poor value if you don't specifically need 4TB in a single-sided form factor. And if you're planning to use it in a portable enclosure, the 22.1 out of 100 portable score is a clear warning sign that this drive isn't optimized for that use case.

The Kingston NV3 4TB is a niche winner. If you need maximum capacity in a single-sided M.2 2280 drive for a laptop or compact build, the 93rd percentile capacity ranking makes this one of the best options available. The 1280 TBW endurance and 5-year warranty provide real peace of mind. But the 15th percentile affordability stings, and the DRAM-less design means you're not getting top-tier random performance. At USD 579 from Newegg, it's a reasonable deal for the right use case. Just don't buy it expecting to beat a WD Black SN850X or Samsung 9100 PRO in benchmarks.
