# Plextor M8Se 512GB NVMe SSD Review (2026)

The Plextor M8Se 512GB is the largest commonly available capacity in Plextor's TLC-based NVMe line — a mainstream drive with 2,400/1,000 MB/s speeds and 360 TBW endurance.

Quick answer: The Plextor M8Se 512GB is a mainstream NVMe SSD that was outperformed by its own sibling — the MLC-based M8Pe — which often cost less at launch. The Samsung 960 EVO 500GB also outclasses it in every metric. The M8Se 512GB is only worth considering at a deep discount. Modern buyers can find newer 3D TLC NVMe drives with better performance, longer warranties, and similar capacity for less money.

## Specifications

| Specification | Value |
| --- | --- |
| Capacity | 512 GB |
| Interface | M.2 or PCIe 3.0 x 4 |
| Controller | Marvell Eldora |
| Memory type | Toshiba TLC |
| DRAM cache | 1GB LPDDR3 |
| Sequential read | 2400 MB/s |
| Sequential write | 1000 MB/s |
| Random read IOPS | 210000 |
| Random write IOPS | 175000 |
| Endurance | 360 TBW |
| MTBF | 1.5 |
| Warranty | 3 years |

## Performance

Plextor rates the M8Se 512GB at up to 2,450 MB/s sequential reads and 1,000 MB/s sequential writes, with 210,000 read IOPS and 175,000 write IOPS. The read speed is competitive for a PCIe 3.0 drive of this generation, but the 1,000 MB/s write ceiling is modest.

Tom's Hardware found the M8Se 512GB trailed the M8Pe in nearly every benchmark, despite sharing the same controller. The TLC NAND writes slower and has lower endurance than the MLC in the M8Pe. The Samsung 960 EVO, which uses 3D TLC with a more advanced controller, outperforms the M8Se across the board. For basic desktop use, the M8Se 512GB delivers NVMe responsiveness; for heavy workloads, the competition is clearly faster.

## Endurance, TBW & Warranty

The M8Se 512GB carries a 360 TBW endurance rating under a three-year limited warranty. At 20 to 50 GB of writes per day, the drive would take roughly 19 to 49 years to reach its endurance ceiling — adequate for mainstream use. The 1.5 million hour MTBF is standard. The three-year warranty is a step down from the M8Pe's five years, reflecting the M8Se's mainstream rather than enthusiast positioning.

## Pros and Cons

**Pros:**

- 2,450 MB/s sequential reads on PCIe 3.0
- 360 TBW endurance is adequate for the capacity
- Available as bare M.2, with heatspreader, or AIC
- Marvell 88SS1093 controller with LDPC
**Cons:**

- 1,000 MB/s writes — low for NVMe
- Three-year warranty versus M8Pe's five years
- Planar TLC NAND — older generation
- M8Pe with MLC was cheaper at launch
- Samsung 960 EVO outclasses it in every metric


## Verdict

The Plextor M8Se 512GB is a mainstream NVMe SSD that was outperformed by its own sibling — the MLC-based M8Pe — which often cost less at launch. The Samsung 960 EVO 500GB also outclasses it in every metric. The M8Se 512GB is only worth considering at a deep discount. Modern buyers can find newer 3D TLC NVMe drives with better performance, longer warranties, and similar capacity for less money.

## Frequently Asked Questions

### Is the Plextor M8Se 512GB good for gaming?

For game loading, yes — the 2,450 MB/s reads and 210K read IOPS handle that workload well. The 512GB capacity fits the OS and a moderate game library. However, newer NVMe drives in the same price range offer faster writes, better endurance, and longer warranties. The M8Se is showing its age.

### Does the Plextor M8Se use MLC or TLC NAND?

The M8Se uses Toshiba 15nm planar TLC (Triple-Level Cell) NAND. This is a different product from the Plextor M8Pe, which uses Toshiba 15nm MLC (Multi-Level Cell) NAND. The TLC flash in the M8Se reduces cost but offers lower endurance and sustained write performance than the MLC in the M8Pe.

### What is the TBW endurance of the Plextor M8Se 512GB?

The M8Se 512GB is rated at 360 TBW (Terabytes Written), covered by a three-year limited warranty. At 20 to 50 GB of writes per day, the drive would take roughly 19 to 49 years to reach its endurance ceiling. This is adequate for mainstream desktop use.

### How does the Plextor M8Se compare to the Samsung 960 EVO?

The Samsung 960 EVO outperforms the M8Se in virtually every benchmark. The Samsung uses 3D V-NAND with Samsung's own controller, while the M8Se uses planar TLC with the Marvell 88SS1093. The Samsung writes faster, reads faster, and includes Samsung's Magician software. If both are available at similar prices, the 960 EVO is the clear pick.

### Is the Plextor M8Se 512GB 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 M8Se is a PCIe 3.0 drive from 2017 with a maximum of 2,450 MB/s reads, far below Sony's requirements.
