# Crucial P2 250GB NVMe SSD Review (2026)

The Crucial P2 250 GB is an entry-level PCIe 3.0 NVMe SSD with a DRAM-less HMB design, but buyers should be aware of a silent QLC NAND swap that degraded performance in later revisions.

Quick answer: The Crucial P2 250 GB is difficult to recommend due to the silent QLC NAND swap that degraded performance under the same product name and part number. Buyers who receive the original TLC revision get an adequate budget boot drive; those who receive the QLC revision get substantially worse performance with no way to tell the difference before purchase. The WD Blue SN550 or Kingston NV2 are safer choices in the budget NVMe segment with more consistent quality control.

## Specifications

## Performance

On the original TLC revision, the Crucial P2 250 GB is rated for up to 2,100 MB/s sequential reads and 1,150 MB/s sequential writes over PCIe 3.0 x4, with 170,000 random read IOPS and 260,000 random write IOPS. These numbers are modest for a PCIe 3.0 NVMe drive and trail the WD Blue SN550.

The E13T controller's firmware is optimized for write performance, which comes at the expense of read latency. Independent reviewers found the P2's read responsiveness lagged behind even some SATA SSDs in game load tests. The Dynamic Write Acceleration SLC cache is small on the 250 GB model, and once it fills, writes drop to native TLC (or QLC) speed.

The QLC NAND swap is the critical concern. Tom's Hardware updated their review to "do not recommend" after discovering the change. The QLC revision's sustained write speed drops to approximately 40 MB/s and read speeds roughly halve compared to the TLC version.

## Endurance, TBW & Warranty

Crucial rates the 250 GB P2 for 150 TBW of write endurance under a five-year limited warranty. The drive includes RAID ECC and Phison's fourth-generation LDPC error correction with multiple adaptation levels. Power loss immunity is integrated. The endurance rating applies to both TLC and QLC revisions, though the QLC version will likely hit its endurance ceiling sooner due to higher write amplification.

## Pros and Cons

**Pros:**

- Low entry price for NVMe storage
- Single-sided M.2 2280 fits laptops
- Five-year warranty
- Integrated power loss immunity
**Cons:**

- Silent QLC NAND swap severely degrades performance
- QLC revision writes as slow as 40 MB/s sustained
- Cannot tell TLC vs QLC revision before purchase
- Read latency trails even SATA SSDs in some tests
- Small SLC cache on 250 GB
- DRAM-less HMB design


## Verdict

The Crucial P2 250 GB is difficult to recommend due to the silent QLC NAND swap that degraded performance under the same product name and part number. Buyers who receive the original TLC revision get an adequate budget boot drive; those who receive the QLC revision get substantially worse performance with no way to tell the difference before purchase. The WD Blue SN550 or Kingston NV2 are safer choices in the budget NVMe segment with more consistent quality control.

## Frequently Asked Questions

### Is the Crucial P2 250GB good for gaming?

Marginally. On the original TLC revision, the P2 250 GB delivers adequate boot drive performance. On the QLC revision, game load times are worse than many SATA SSDs. Because buyers cannot determine which revision they will receive, the P2 250 GB is a risky choice for gaming. The WD Blue SN550 offers more consistent performance at a similar price.

### What is the QLC NAND swap issue with the Crucial P2?

Crucial silently replaced the TLC NAND flash in the P2 with QLC NAND without changing the product name, model number, or issuing an announcement. Tom's Hardware found the QLC revision performs significantly worse: sustained writes drop to approximately 40 MB/s (slower than most hard drives), read speeds are roughly halved, and overall performance is well below what reviews of the original TLC version showed. The updated review carries a \"do not recommend\" verdict.

### Does the Crucial P2 have a DRAM cache?

No. The P2 uses Phison's E13T DRAM-less controller with NVMe Host Memory Buffer (HMB), borrowing a small amount of system RAM for flash translation layer tables. The HMB implementation is optimized for write performance, which means read latency suffers -- the controller prioritizes write readiness over read responsiveness.

### What is the TBW endurance of the Crucial P2 250GB?

The 250 GB P2 is rated for 150 TBW (terabytes written) under a five-year limited warranty, regardless of whether it uses TLC or QLC NAND. The QLC revision may exhaust this endurance faster due to higher write amplification from the less durable NAND cells.

### What is a better alternative to the Crucial P2?

The WD Blue SN550 is a safer budget NVMe choice with consistent performance and no known silent hardware revisions. The Kingston NV2 also competes in this segment, though it too has seen hardware changes between revisions. For slightly more budget, the Samsung 970 EVO Plus offers DRAM-equipped performance with no QLC concerns.
