# Kingston NV2 256GB -- Budget PCIe 4.0 DRAM-Less NVMe Review (2026)

The Kingston NV2 256 GB is the entry-level capacity in Kingston's budget PCIe 4.0 line, built on the Phison E21T DRAM-less controller for basic desktop and office builds.

Quick answer: The 256 GB NV2 is the absolute minimum capacity in Kingston's Gen4 budget line. Its 3,500 MB/s reads are adequate for OS boot, but the 1,300 MB/s writes and 80 TBW endurance reflect its entry-level positioning. At this capacity, the WD Blue SN580 256 GB and HP FX900 256 GB are direct competitors. Choose the cheapest option for a budget boot drive. For any workload beyond basic office use, step up to 512 GB or 1 TB.

## Specifications

| Specification | Value |
| --- | --- |
| Capacity | 256 GB |
| Interface | M.2 4.0 x 4 |
| Controller | Phison PS5021-E21 |
| Memory type | Toshiba 3D TLC |
| DRAM cache | HMB (DRAM-less) |
| Sequential read | 3500 MB/s |
| Sequential write | 1300 MB/s |
| Random read IOPS | 3000000 |
| Random write IOPS | 3000000 |
| Endurance | 80 TBW |
| MTBF | 1500000 |
| Warranty | 3 years |

## Performance

The 256 GB NV2 delivers 3,500/1,300 MB/s sequential reads and writes. The HMB architecture provides adequate random I/O for light desktop use. Under sustained writes, the small NAND pool limits SLC cache size, and the drive transitions to native speeds quickly. Gaming load times are adequate but the 256 GB capacity holds only a handful of modern titles.

## Endurance, TBW & Warranty

Kingston covers the NV2 256 GB with a three-year warranty limited by 80 TBW, equivalent to roughly 73 GB/day over three years. At office-use write rates of 5-10 GB/day this spans 22-44 years.

## Pros and Cons

**Pros:**

- 3,500 MB/s reads -- adequate for boot drive
- DRAM-less HMB design keeps price low
- Single-sided PCB -- thin-laptop compatible
- Widely available
**Cons:**

- 1,300 MB/s writes -- among the slowest Gen4 drives
- 80 TBW endurance -- lowest in the lineup
- 256 GB is minimal for modern use
- Variable hardware -- components may change between batches


## Verdict

The 256 GB NV2 is the absolute minimum capacity in Kingston's Gen4 budget line. Its 3,500 MB/s reads are adequate for OS boot, but the 1,300 MB/s writes and 80 TBW endurance reflect its entry-level positioning. At this capacity, the WD Blue SN580 256 GB and HP FX900 256 GB are direct competitors. Choose the cheapest option for a budget boot drive. For any workload beyond basic office use, step up to 512 GB or 1 TB.

## Frequently Asked Questions

### Is the 256GB NV2 good for basic PC builds?

Yes — 3,500 MB/s reads provide responsive OS boot and application launches. The 256 GB capacity is sufficient for Windows and core applications. For games or content, step up to at least 512 GB.

### What is the TBW of the 256GB NV2?

Rated for 80 TBW over three years, equivalent to roughly 73 GB/day. At office-use rates of 5-10 GB/day this lasts 22-44 years.

### Does the NV2 have DRAM?

No — the NV2 is a DRAM-less design using Host Memory Buffer (HMB), which borrows a small amount of system RAM for the flash translation layer. This keeps costs down.

### What controller does the NV2 use?

The Phison PS5021-E21T — a budget PCIe 4.0 x4 controller designed for DRAM-less drives. Note that Kingston uses variable hardware, so some NV2 batches may ship with different controllers.

### How does it compare to the WD Blue SN580 256GB?

Both are DRAM-less budget PCIe 4.0 drives. The SN580 rates at 4,150/1,500 MB/s — slightly faster on both reads and writes. At similar pricing, the SN580 edges ahead.
