Kingston NV3 4TB: bulk capacity at a budget price (2026)
The Kingston NV3 4TB pairs the line's full rated speed with its largest capacity and highest endurance rating, at a price well under most brand-name flagship drives.
Controller & Memory
Kingston builds the NV3 around a DRAM-less controller paired with QLC NAND and Host Memory Buffer instead of dedicated DRAM, in the standard M.2 2280 form factor over PCIe 4.0 x4. Reviewers have documented that Kingston ships different controller and NAND combinations under the same NV3 name depending on production batch, so exact benchmark results can vary slightly between individual drives - a known quirk of this budget line rather than a defect in any single unit.
At 4 TB, the NV3 matches the 2TB capacity's full rated speed of 6,000 MB/s reads and 5,000 MB/s writes, while endurance climbs to 1,280 TBW, the highest in the entire line, under the same 3-year warranty that covers every NV3 capacity equally. This is the largest and most storage-dense option in the range, aimed at buyers who want maximum capacity without stepping up to a pricier DRAM-equipped flagship drive from a bigger name-brand competitor.
Against DRAM-less budget rivals like the Crucial P3 Plus 4TB and Samsung 990 EVO Plus 4TB, the NV3 competes strongly on price while matching them on rated sequential speed, making it a compelling pick for large game libraries, media archives, or bulk storage pools on a tight budget without sacrificing much on paper.

NV3 Performance & Benchmarks
Kingston rates the NV3 4TB at up to 6,000 MB/s sequential reads and 5,000 MB/s sequential writes over PCIe 4.0 x4, the full rated speed of the line, matching the well-reviewed 2TB capacity. Random IOPS figures for this specific capacity aren't reliably confirmed, so treat any specific number seen elsewhere with some caution rather than as a guaranteed figure across every unit sold.

- Kingston NV3 4 TB (this drive): 6,000 MB/s read, 5,000 MB/s write
As a QLC, DRAM-less drive, the NV3 leans on an SLC write cache that's proportionally larger in absolute terms at 4TB than on smaller capacities, giving more headroom before write speed drops toward the native QLC ceiling on a very large sustained transfer. For large game libraries, media archives, and general bulk storage where capacity matters more than peak sustained write speed, the 4TB NV3 delivers strong value, though video editors moving hundreds of gigabytes in one continuous session will still notice the eventual cache exhaustion more than gamers will.

Endurance, TBW & Warranty
Kingston rates the NV3 4TB at 1,280 TBW of total write endurance, the highest in the entire NV3 line, backed by a 3-year limited warranty. At a typical 20-50 GB of writes per day, that endurance budget lasts roughly 70 to 175 years before hitting the rated limit, making endurance a complete non-issue at this capacity. The MTBF rating is 2,000,000 hours, a statistical reliability figure describing failure rates across a large population of drives rather than a promise for any individual unit.
The 3-year warranty is shorter than the 5-year terms some competitors offer, though it holds consistently across every NV3 capacity and is respectable for a budget QLC drive at this price and size.

Verdict: Is the NV3 Worth It in 2026?
The Kingston NV3 4TB suits buyers who want genuinely large capacity - a huge game library, media archive, or bulk storage pool - backed by the line's highest endurance rating and a budget-friendly price. It's a weaker choice for video editors or anyone doing constant very large sustained writes, where the QLC architecture's cache limits eventually show up regardless of capacity. Buyers who want more consistent sustained write performance at a similar capacity should consider the Samsung 990 EVO Plus 4TB. Overall, the NV3 4TB delivers bulk capacity and strong endurance that few budget rivals match at this price.
