# Crucial P2 500GB NVMe SSD Review (2026)

The Crucial P2 500 GB is a budget DRAM-less NVMe SSD that was originally competent, but a silent QLC NAND swap under the same model number means buyers may receive a drastically slower drive than reviews describe.

Quick answer: The Crucial P2 500 GB cannot be recommended due to the silent QLC NAND swap. Even the original TLC revision was mediocre compared to the WD Blue SN550, with lower write speeds and read responsiveness. The QLC revision is substantially worse, with hard-drive-level sustained writes. For budget NVMe storage, the WD Blue SN550 offers more consistent performance, better-documented specs, and no history of silent hardware changes.

## Performance

On the original TLC revision, the 500 GB P2 is rated for up to 2,300 MB/s sequential reads and 940 MB/s sequential writes over PCIe 3.0 x4, with 95,000 random read IOPS and 215,000 random write IOPS. The read IOPS are notably low -- lower than the 250 GB model's 170K -- and the write speed of 940 MB/s is below the 250 GB model's 1,150 MB/s.

The E13T controller's firmware prioritizes write latency over read responsiveness, which hurts performance in read-heavy workloads like game loading. The small Dynamic Write Acceleration SLC cache fills quickly on the 500 GB model, and direct-to-TLC writes are slow.

The QLC revision changes the picture entirely. Sustained writes drop to 40 MB/s, read speeds halve in real-world tests, and overall performance is four times slower than the TLC version in file transfer tests. Tom's Hardware issued a "do not recommend" verdict for the P2 after the QLC swap was discovered.

## Endurance, TBW & Warranty

Crucial rates the 500 GB P2 for 300 TBW of write endurance under a five-year limited warranty. The drive includes RAID ECC and Phison fourth-generation LDPC error correction with multiple adaptation levels. Integrated power loss immunity provides some protection against data corruption during unexpected shutdowns. The endurance rating applies to both TLC and QLC revisions.

## Pros and Cons

**Pros:**

- Low price for NVMe storage
- 300 TBW endurance on the TLC revision
- Single-sided M.2 2280
- Five-year warranty
- Integrated power loss immunity
**Cons:**

- Silent QLC NAND swap ruins performance
- QLC revision: 40 MB/s sustained writes
- Cannot distinguish TLC from QLC at purchase
- 940 MB/s writes (TLC) below the 250GB model
- Very low 95K random read IOPS
- Read latency worse than SATA SSDs in some tests


## Verdict

The Crucial P2 500 GB cannot be recommended due to the silent QLC NAND swap. Even the original TLC revision was mediocre compared to the WD Blue SN550, with lower write speeds and read responsiveness. The QLC revision is substantially worse, with hard-drive-level sustained writes. For budget NVMe storage, the WD Blue SN550 offers more consistent performance, better-documented specs, and no history of silent hardware changes.

## Frequently Asked Questions

### Is the Crucial P2 500GB good for gaming?

Not recommended. On the original TLC revision, the P2 500 GB is an adequate budget drive, but game load times trail even some SATA SSDs due to poor read latency optimization. On the QLC revision (which is what most buyers will receive now), performance is significantly worse. Tom's Hardware issued a \"do not recommend\" for the P2 after discovering the QLC swap.

### What is the QLC NAND swap issue with the Crucial P2 500GB?

Crucial replaced the TLC NAND in the P2 with QLC NAND without changing the product name or model number. The QLC revision has sustained write speeds of approximately 40 MB/s (slower than most hard drives), roughly half the read speed of the TLC version in real-world tests, and overall performance about four times worse than the TLC revision. There is no way to determine which version is in a sealed box.

### Does the Crucial P2 500GB have a DRAM cache?

No. The P2 uses Phison's E13T DRAM-less controller with NVMe Host Memory Buffer (HMB). The E13T's firmware is optimized for write performance, which hurts read responsiveness. In game load tests, the P2 500 GB was slower than the Crucial MX500 SATA SSD.

### What is the TBW endurance of the Crucial P2 500GB?

The 500 GB P2 is rated for 300 TBW (terabytes written) under a five-year limited warranty. This applies to both TLC and QLC revisions. At 15 GB of writes per day, 300 TBW translates to roughly 55 years of use on paper. The QLC revision may exhaust endurance faster due to higher write amplification.

### What is a better alternative to the Crucial P2 500GB?

The WD Blue SN550 is the better budget NVMe choice. It offers consistent performance, no history of silent hardware revisions, and better real-world responsiveness. For slightly more budget, the Samsung 970 EVO Plus provides DRAM-equipped performance. Both are safer choices than the P2.
