# Plextor M8Pe 1TB NVMe SSD Review (2026)

The Plextor M8Pe 1TB is the flagship of Plextor's first NVMe line — a Toshiba MLC drive with 1 GB of LPDDR3 DRAM, 2,500/1,400 MB/s speeds, and a five-year warranty.

Quick answer: The Plextor M8Pe 1TB is a capable NVMe SSD with MLC NAND, a generous 1 GB DRAM cache, and a five-year warranty — a combination of features that is increasingly rare. Its performance is competitive with the Samsung 950 Pro and OCZ RD400 from the same era, though Samsung edges ahead in power efficiency. Buyers who find the M8Pe 1TB at a discount get a durable drive with MLC endurance. Those seeking the best performance per dollar should look at newer NVMe drives, which outperform this 2016 design in raw throughput.

| Random write IOPS | 240000 |
| Endurance | 768 TBW |
| MTBF | 2.4 |
| Warranty | 5 years |

## Performance

Plextor rates the M8Pe 1TB at up to 2,500 MB/s sequential reads and 1,400 MB/s sequential writes, with 280,000 read IOPS and 240,000 write IOPS. These are the highest numbers in the M8Pe family.

AnandTech's review of the 512GB M8Pe showed it performing competitively with the Samsung 950 Pro in sequential workloads, with Samsung maintaining edges in random IO and power efficiency. The 1TB model benefits from more NAND dies and double the DRAM, which should improve sustained write performance further. The MLC NAND provides consistent write performance without the SLC cache drop-off that TLC drives exhibit during sustained transfers. Power consumption is higher than Samsung's drives, particularly in the M8PeY AIC variant which adds voltage conversion and LED overhead.

## Endurance, TBW & Warranty

The M8Pe 1TB carries a five-year limited warranty. Plextor does not publish a specific TBW rating for the 1TB model, but the endurance is proportional to the MLC NAND capacity and is expected to exceed the 768 TBW rating of the 512GB model. The 2.4 million hour MTBF is above average for consumer SSDs. The five-year warranty was generous for the 2016 market and remains competitive today.

## Pros and Cons

**Pros:**

- 2,500 MB/s reads, 1,400 MB/s writes on PCIe 3.0
- 1,024 MB LPDDR3 DRAM — double the smaller capacities
- Toshiba 15nm MLC NAND for strong endurance
- Five-year warranty
- Consistent MLC write performance without SLC volatility
**Cons:**

- Double-sided PCB may not fit some ultra-thin laptops
- Trails Samsung 950 Pro in power efficiency
- 15nm planar MLC — older NAND generation
- Endurance TBW not published for 1TB model


## Verdict

The Plextor M8Pe 1TB is a capable NVMe SSD with MLC NAND, a generous 1 GB DRAM cache, and a five-year warranty — a combination of features that is increasingly rare. Its performance is competitive with the Samsung 950 Pro and OCZ RD400 from the same era, though Samsung edges ahead in power efficiency. Buyers who find the M8Pe 1TB at a discount get a durable drive with MLC endurance. Those seeking the best performance per dollar should look at newer NVMe drives, which outperform this 2016 design in raw throughput.

## Frequently Asked Questions

### Is the Plextor M8Pe 1TB good for gaming?

Yes. The 2,500 MB/s reads and 280K read IOPS provide fast game loading, and the 1TB capacity holds a full OS plus a large game library. The MLC NAND maintains consistent performance during game installations and updates without the SLC cache dips that TLC drives can exhibit.

### Does the Plextor M8Pe 1TB have a DRAM cache?

Yes, and it is generous. The M8Pe 1TB includes 1,024 MB (1 GB) of LPDDR3 DRAM on the PCB — twice the 512 MB found on the 128GB, 256GB, and 512GB models. This large DRAM cache handles the mapping tables for the full 1TB capacity efficiently.

### What is the endurance of the Plextor M8Pe 1TB?

Plextor does not publish a specific TBW rating for the 1TB model. Based on the 768 TBW rating of the 512GB model and the use of MLC NAND, the 1TB endurance is expected to be proportionally higher. The drive is backed by a five-year warranty regardless of endurance.

### Is the Plextor M8Pe 1TB compatible with the PS5?

No. The PS5 requires a PCIe 4.0 NVMe SSD with a recommended read speed of 5,500 MB/s or higher. The M8Pe is a PCIe 3.0 drive with a maximum of 2,500 MB/s reads, which does not meet Sony's published requirements.

### How does the Plextor M8Pe 1TB compare to the OCZ RD400 1TB?

Both use Toshiba NAND with PCIe 3.0 x4 NVMe interfaces. The OCZ RD400 uses Toshiba's own NVMe controller, while the M8Pe uses the Marvell 88SS1093. The RD400 posts slightly higher sequential read speeds (2,600 MB/s versus 2,500 MB/s) and similar writes. Both carry five-year warranties. The M8Pe offers more DRAM (1 GB versus 512 MB on the RD400) and a factory heatspreader option.

### Does the Plextor M8Pe 1TB work in a laptop?

Most laptops, yes — but not all. The 1TB model is the only M8Pe capacity that uses a double-sided PCB, meaning components are on both sides of the board. A small number of ultra-thin laptops only accept single-sided M.2 SSDs. Check your laptop's specifications before purchasing. The 128GB through 512GB models are all single-sided.
