# Crucial P5 Plus 1TB -- In-House Micron PCIe 4.0 NVMe SSD Review (2026)

The Crucial P5 Plus 1 TB is a mid-range PCIe 4.0 NVMe SSD built on an in-house Micron controller and TLC NAND, delivering solid Gen4 performance at mainstream pricing.

Quick answer: The 1 TB P5 Plus is a solid mainstream PCIe 4.0 choice when priced below the Phison E18 flagships. Its in-house Micron controller provides good power efficiency and thermal management. The 600 TBW endurance is adequate for any consumer workload. For PS5 use, the 6,600 MB/s reads are well above the minimum. Buyers should compare pricing against the WD Black SN850X and Samsung 980 Pro — at similar prices, those E18-adjacent drives offer slightly higher peak throughput, but when the P5 Plus is discounted, it represents good value.

## Specifications

| Specification | Value |
| --- | --- |
| Capacity | 1 TB |
| Interface | M.2 4.0 x 4 |
| Controller | Crucial |
| Memory type | Micron TLC |
| DRAM cache | LPDDR4 |
| Sequential read | 6600 MB/s |
| Sequential write | 5000 MB/s |
| Random read IOPS | 720000 |
| Random write IOPS | 700000 |
| Endurance | 600 TBW |
| MTBF | 2000000 |
| Warranty | 5 years |

## Performance

The 1 TB P5 Plus delivers 6,600/5,000 MB/s sequential reads and writes with read IOPS around 720,000 and write IOPS near 700,000. Under real-world sustained write workloads, the Micron controller handles SLC cache transitions smoothly, maintaining respectable speeds after the pseudo-SLC cache depletes. Gaming load times are competitive with Phison E18 flagships — the difference between 6,600 and 7,100 MB/s reads is imperceptible at the game level.

## Endurance, TBW & Warranty

Crucial covers the P5 Plus 1 TB with a five-year warranty limited by 600 TBW, equivalent to roughly 328 GB/day over five years. The 2 TB model carries 1,200 TBW. Crucial backing from Micron means the warranty process is straightforward. TCG Opal 2.0 encryption support is included.

## Pros and Cons

**Pros:**

- 6,600/5,000 MB/s -- competitive PCIe 4.0 mainstream
- In-house Micron controller -- good power efficiency
- Single-sided PCB -- fits thin laptops
- PS5-compatible
- TCG Opal 2.0 hardware encryption
**Cons:**

- Below Gen4 ceiling -- slower than Phison E18 flagships
- In-house controller limits community firmware support
- 600 TBW endurance -- lower than competing 1TB E18 drives


## Verdict

The 1 TB P5 Plus is a solid mainstream PCIe 4.0 choice when priced below the Phison E18 flagships. Its in-house Micron controller provides good power efficiency and thermal management. The 600 TBW endurance is adequate for any consumer workload. For PS5 use, the 6,600 MB/s reads are well above the minimum. Buyers should compare pricing against the WD Black SN850X and Samsung 980 Pro — at similar prices, those E18-adjacent drives offer slightly higher peak throughput, but when the P5 Plus is discounted, it represents good value.

## Frequently Asked Questions

### Is the Crucial P5 Plus 1TB good for PS5?

Yes — 6,600 MB/s reads exceed the 5,500 MB/s minimum. The single-sided PCB and standard M.2 2280 form factor fit without issues. Gaming load times are competitive with any PCIe 4.0 drive.

### What controller does the P5 Plus use?

An in-house Micron-designed controller, not a third-party Phison or Silicon Motion chip. This gives Crucial control over firmware and power efficiency but means fewer community firmware options compared to Phison E18 drives.

### What is the TBW of the 1TB P5 Plus?

Rated for 600 TBW over five years, equivalent to roughly 328 GB/day. At typical gaming write rates this lasts decades. The 2TB model carries 1,200 TBW.

### How does it compare to the WD Black SN850X 1TB?

The SN850X leads on peak reads (7,300 vs 6,600 MB/s) using the WD G2 controller. Both load games identically. The SN850X is generally stronger but often costs more. When the P5 Plus is discounted, it offers good value.

### Does it have DRAM?

Yes — the 1 TB model includes 1 GB of LPDDR4 DRAM cache, which helps with random I/O performance and drive longevity compared to DRAM-less HMB designs.
