# Plextor M8Pe 512GB NVMe SSD Review (2026)

The Plextor M8Pe 512GB is the capacity AnandTech reviewed — a Toshiba MLC NVMe drive with 512 MB DRAM, 2,300/1,300 MB/s speeds, and a generous 768 TBW endurance rating.

Quick answer: The Plextor M8Pe 512GB is a well-rounded NVMe SSD with genuine MLC NAND, a hardware DRAM cache, and 768 TBW of endurance — specifications that are rare in this TLC-dominated market. Its performance is competitive with the Samsung 950 Pro and Toshiba OCZ RD400, though Samsung edges ahead in efficiency and random IO. Buyers who value MLC endurance and a five-year warranty will find the M8Pe 512GB a durable choice. Those seeking maximum performance per dollar should consider newer PCIe 3.0 or 4.0 TLC drives, which outperform this 2016 design in raw speed.

## Specifications

| Specification | Value |
| --- | --- |
| Capacity | 512 GB |
| Interface | M.2 or PCIe 3.0 x 4 |
| Controller | Marvell 88SS1093 |

| DRAM cache | 512MB LPDDR3 |
| Sequential read | 2300 MB/s |
| Sequential write | 1300 MB/s |
| Random read IOPS | 260000 |
| Random write IOPS | 250000 |
| Endurance | 768 TBW |
| MTBF | 2.4 |
| Warranty | 5 years |

## Performance

Plextor rates the M8Pe 512GB at up to 2,300 MB/s sequential reads and 1,300 MB/s sequential writes, with 260,000 read IOPS and 250,000 write IOPS. AnandTech's comprehensive benchmark suite found the M8Pe 512GB performing competitively with the Samsung 950 Pro and Toshiba OCZ RD400 in sequential workloads.

The Samsung 950 Pro maintained an edge in random IO and power efficiency, benefiting from Samsung's vertically integrated controller-and-NAND design. The M8Pe held its own in sequential transfers and offered consistent performance without dramatic drops during sustained writes — a benefit of the MLC NAND and DRAM cache combination. Power consumption was higher than the Samsung, particularly in the M8PeY AIC variant which draws additional power for its LEDs and adapter circuitry.

## Endurance, TBW & Warranty

The M8Pe 512GB carries a 768 TBW endurance rating backed by a five-year limited warranty. At 20 to 50 GB of writes per day, the drive would take roughly 42 to 105 years to exhaust its endurance — an exceptionally long lifespan enabled by the MLC NAND. The 2.4 million hour MTBF is above average. The five-year warranty was generous for the 2016 NVMe market and remains competitive.

## Pros and Cons

**Pros:**

- 2,300 MB/s reads, 1,300 MB/s writes on PCIe 3.0
- 512 MB LPDDR3 DRAM cache
- 768 TBW endurance with MLC NAND
- Five-year warranty
- Consistent sustained write performance from MLC
**Cons:**

- Trails Samsung 950 Pro in random IO and efficiency
- M8PeY AIC version wastes power on LEDs
- 15nm planar MLC — older NAND generation
- No included software toolbox


## Verdict

The Plextor M8Pe 512GB is a well-rounded NVMe SSD with genuine MLC NAND, a hardware DRAM cache, and 768 TBW of endurance — specifications that are rare in this TLC-dominated market. Its performance is competitive with the Samsung 950 Pro and Toshiba OCZ RD400, though Samsung edges ahead in efficiency and random IO. Buyers who value MLC endurance and a five-year warranty will find the M8Pe 512GB a durable choice. Those seeking maximum performance per dollar should consider newer PCIe 3.0 or 4.0 TLC drives, which outperform this 2016 design in raw speed.

## Frequently Asked Questions

### Is the Plextor M8Pe 512GB good for gaming?

Yes. The 2,300 MB/s reads and 260K read IOPS handle game loading well above SATA levels. The 512GB capacity fits the OS plus a solid game library. The MLC NAND provides consistent performance during game installations without the SLC cache volatility of TLC drives.

### Does the Plextor M8Pe 512GB have a DRAM cache?

Yes. The M8Pe 512GB includes 512 MB of LPDDR3 DRAM on the PCB dedicated to the flash translation layer. This hardware DRAM cache provides a performance advantage over DRAM-less NVMe drives, particularly during sustained random IO workloads.

### What is the TBW endurance of the Plextor M8Pe 512GB?

The M8Pe 512GB is rated at 768 TBW (Terabytes Written), backed by a five-year warranty. At 20 to 50 GB of writes per day, the drive would take 42 to 105 years to exhaust its endurance. The MLC NAND is the key contributor to this strong endurance rating, which significantly exceeds typical TLC drives at the same capacity.

### How does the Plextor M8Pe compare to the Samsung 950 Pro?

Both are 2016-era PCIe 3.0 NVMe drives with MLC NAND. The Samsung 950 Pro uses Samsung's vertically integrated UBX controller and 32-layer V-NAND, while the M8Pe uses the Marvell 88SS1093 with Toshiba 15nm MLC. The Samsung leads in random IO performance and power efficiency. The M8Pe was typically priced lower and offers similar sequential speeds. Both carry five-year warranties.

### What is the difference between the M8PeGN, M8PeG, and M8PeY?

The M8PeGN is the bare M.2 2280 module with no additional cooling. The M8PeG adds a thin aluminum heatspreader that helps with thermal throttling but may not fit in some laptops. The M8PeY is a PCIe add-in card that houses the M.2 module under a large heatsink with red LED lighting. Performance is identical across all three; the difference is cooling and form factor.
