# Plextor M8Pe 128GB NVMe SSD Review (2026)

The Plextor M8Pe 128GB is the smallest capacity in Plextor's first true NVMe MLC line — a drive with Toshiba 15nm MLC and the Marvell 88SS1093 controller that targets entry-level NVMe buyers.

Quick answer: The Plextor M8Pe 128GB is a capable entry-level NVMe SSD with genuine MLC NAND and a DRAM cache — features that many cheaper TLC and DRAM-less drives lack. Its 500 MB/s write speed limits it to light workloads, but as a boot drive for a budget build, the MLC endurance and five-year warranty are real assets. Modern buyers can find faster NVMe drives at similar prices, but few offer MLC NAND with hardware DRAM at this capacity.

## Specifications

| Specification | Value |
| --- | --- |
| Capacity | 128 GB |
| Interface | M.2 or PCIe 3.0 x 4 |
| Controller | Marvell 88SS1093 |

| DRAM cache | 512MB LPDDR3 |
| Sequential read | 1600 MB/s |
| Sequential write | 500 MB/s |
| Random read IOPS | 120000 |
| Random write IOPS | 130000 |
| Endurance | 192 TBW |
| MTBF | 2.4 |
| Warranty | 5 years |

## Performance

Plextor rates the M8Pe 128GB at up to 1,600 MB/s sequential reads and 500 MB/s sequential writes, with 120,000 read IOPS and 130,000 write IOPS. The write speed is the lowest in the M8Pe family — less than half the 256GB model's 900 MB/s and far behind the 1TB's 1,400 MB/s.

AnandTech's review of the M8Pe 512GB found it competitive with the Samsung 950 Pro and Toshiba OCZ RD400 in some tests, though Samsung's vertically integrated approach gave it an edge in power efficiency and consistency. The 128GB model, with fewer NAND dies, will show lower sustained write performance and smaller SLC cache. The DRAM cache does help maintain mapping table performance during random IO workloads. For basic NVMe use — boot drive, applications, light gaming — the M8Pe 128GB delivers a clear upgrade over SATA.

## Endurance, TBW & Warranty

The Plextor M8Pe 128GB carries a 192 TBW endurance rating with a five-year limited warranty. At a typical consumer write volume of 10 to 30 GB per day, the endurance ceiling is roughly 17 to 52 years away. The 2.4 million hour MTBF is above average for consumer SSDs. The five-year warranty was a strong selling point at launch, outlasting the three-year terms common on entry-level NVMe drives.

## Pros and Cons

**Pros:**

- 1,600 MB/s sequential reads on PCIe 3.0
- 512 MB LPDDR3 DRAM cache
- Toshiba 15nm MLC NAND for strong endurance
- Five-year warranty
- Available as bare M.2, with heatspreader, or AIC
**Cons:**

- 500 MB/s writes — barely above SATA levels
- 128GB capacity limits practical use
- 15nm planar MLC — older NAND generation
- M8PeY AIC version adds cost for minimal benefit


## Verdict

The Plextor M8Pe 128GB is a capable entry-level NVMe SSD with genuine MLC NAND and a DRAM cache — features that many cheaper TLC and DRAM-less drives lack. Its 500 MB/s write speed limits it to light workloads, but as a boot drive for a budget build, the MLC endurance and five-year warranty are real assets. Modern buyers can find faster NVMe drives at similar prices, but few offer MLC NAND with hardware DRAM at this capacity.

## Frequently Asked Questions

### Is the Plextor M8Pe 128GB good for gaming?

For game loading, yes — the 1,600 MB/s reads and 120K read IOPS outperform SATA. However, the 128GB capacity holds the OS and only one or two games. As a boot drive that also runs a few applications, it works well. For a dedicated game library, the 256GB or 512GB model is a better investment.

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

Yes. The M8Pe 128GB includes 512 MB of LPDDR3 DRAM on the PCB dedicated to the flash translation layer. The 1TB model doubles this to 1,024 MB. Having a dedicated DRAM cache is a genuine hardware advantage over DRAM-less NVMe drives, particularly for sustained random IO workloads.

### What is the TBW endurance of the Plextor M8Pe 128GB?

The M8Pe 128GB is rated at 192 TBW (Terabytes Written), backed by a five-year warranty. At 10 to 30 GB of writes per day — typical for a light-use desktop — the drive would take 17 to 52 years to exhaust its endurance. The MLC NAND contributes to the strong endurance rating relative to the small capacity.

### Is the Plextor M8Pe 128GB slower than the larger capacities?

Significantly. The 128GB writes at 500 MB/s, compared to 900 MB/s on the 256GB, 1,300 MB/s on the 512GB, and 1,400 MB/s on the 1TB. Random performance also scales with capacity: 120K read IOPS versus 280K on the 1TB. This is normal — fewer NAND dies means less parallelism for write operations.

### Is the Plextor M8Pe 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 from 2016 with a maximum of 2,500 MB/s reads on the 1TB model and 1,600 MB/s on the 128GB.
