Kingston NV2 512GB -- Budget PCIe 4.0 DRAM-Less NVMe Review (2026)
Quick answer
The 512 GB NV2 is the practical minimum for a budget Gen4 boot-and-gaming drive.
Read: 3500 MB/s Write: 2100 MB/s Endurance: 160 TBW Warranty: 3 years Interface: M.2 4.0 x 4
The Kingston NV2 512 GB doubles the capacity and write speed of the 256 GB variant while retaining the Phison E21T DRAM-less platform, making it a viable budget boot-and-gaming drive.
Controller & Memory
The NV2 512 GB uses the Phison PS5021-E21T controller with HMB rather than onboard DRAM cache. At 512 GB it is rated at 3,500 MB/s reads and 2,100 MB/s writes — the write speed increases thanks to greater NAND parallelism. Endurance is 160 TBW, backed by a three-year warranty. The single-sided PCB fits thin laptops.
At 512 GB, the NV2 transitions from an OS-only drive to a boot-and-light-gaming volume. The 2,100 MB/s writes are competitive with other budget Gen4 drives. The HMB architecture provides adequate random I/O for gaming and general productivity. For users who do not need high-end sustained performance, the NV2 512 GB offers a good balance of capacity and price.

NV2 Performance & Benchmarks
The 512 GB NV2 delivers 3,500/2,100 MB/s sequential reads and writes. The HMB design handles light-to-moderate sustained writes adequately. Gaming load times are competitive with any PCIe 4.0 drive. Under heavy sustained writes, the drive transitions to native NAND speeds faster than DRAM-equipped alternatives.

Verdict: Is the NV2 Worth It in 2026?
The 512 GB NV2 is the practical minimum for a budget Gen4 boot-and-gaming drive. Its 3,500/2,100 MB/s speeds are competitive with the WD Blue SN580 512 GB and HP FX900 512 GB. The 160 TBW endurance is adequate for light-to-moderate use. The DRAM-less HMB design means it is not ideal for sustained professional workloads, but for gaming, web browsing, and office productivity, it delivers a smooth experience. Choose based on which of the three is cheapest.
