# Plextor M8Se 256GB NVMe SSD Review (2026)

The Plextor M8Se 256GB is a mainstream PCIe 3.0 NVMe SSD with Toshiba planar TLC NAND — a drive that fills the gap between SATA and high-end NVMe at a midrange price.

Quick answer: The Plextor M8Se 256GB delivers basic NVMe performance with Toshiba planar TLC NAND and a three-year warranty. It is a competent boot drive, but the MLC-based Plextor M8Pe often sold for less and offered better performance with a longer warranty. Modern buyers looking for a 256GB NVMe boot drive can find newer 3D TLC drives with five-year warranties and faster writes at similar or lower prices.

## Specifications

| Specification | Value |
| --- | --- |
| Capacity | 256 GB |
| Interface | M.2 or PCIe 3.0 x 4 |
| Controller | Marvell Eldora |
| Memory type | Toshiba TLC |
| DRAM cache | 512MB LPDDR3 |
| Sequential read | 2400 MB/s |
| Sequential write | 1000 MB/s |
| Random read IOPS | 210000 |
| Random write IOPS | 175000 |
| Endurance | 220 TBW |
| MTBF | 1.5 |
| Warranty | 3 years |

## Performance

Plextor rates the M8Se 256GB at up to 2,400 MB/s sequential reads and 1,000 MB/s sequential writes, with 210,000 read IOPS and 175,000 write IOPS. Tom's Hardware found the M8Se trailed the MLC-based M8Pe across most benchmarks despite using the same controller — the TLC NAND is the limiting factor.

Real-world performance is adequate for everyday desktop use. Boot times, application launches, and general file operations feel responsive and well above SATA speeds. Sustained writes past the SLC cache drop to native TLC levels, which on 15nm planar flash are modest compared to modern 3D TLC drives. For a 256GB boot drive handling mostly reads, the M8Se is competent; for heavy write workloads, look elsewhere.

## Endurance, TBW & Warranty

The M8Se 256GB carries a 220 TBW endurance rating under a three-year limited warranty, limited by whichever comes first. At 20 to 40 GB of writes per day, the drive would take roughly 15 to 30 years to reach its endurance ceiling. The 1.5 million hour MTBF is standard. The three-year warranty is shorter than the M8Pe's five years, reflecting the M8Se's mainstream positioning.

## Pros and Cons

**Pros:**

- 2,400 MB/s sequential reads on PCIe 3.0
- Marvell 88SS1093 controller with LDPC error correction
- Available as bare M.2, with heatspreader, or AIC
- 220 TBW endurance is adequate for a boot drive
**Cons:**

- 1,000 MB/s writes — low for NVMe
- Three-year warranty versus five years on M8Pe
- Planar TLC NAND — older generation
- M8Pe with MLC was sometimes cheaper at launch


## Verdict

The Plextor M8Se 256GB delivers basic NVMe performance with Toshiba planar TLC NAND and a three-year warranty. It is a competent boot drive, but the MLC-based Plextor M8Pe often sold for less and offered better performance with a longer warranty. Modern buyers looking for a 256GB NVMe boot drive can find newer 3D TLC drives with five-year warranties and faster writes at similar or lower prices.

## Frequently Asked Questions

### Is the Plextor M8Se 256GB good for gaming?

For basic game loading, yes. The 2,400 MB/s reads are well above SATA and handle game load times competently. The 256GB capacity fits the OS plus a few games. For a dedicated game drive, the 512GB or 1TB model gives more breathing room. Newer NVMe drives in the same price range offer better write performance with 3D TLC NAND.

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

The M8Se uses Toshiba 15nm planar TLC NAND. This is different from the Plextor M8Pe, which uses Toshiba 15nm MLC NAND. TLC stores three bits per cell versus MLC's two, reducing cost but lowering endurance and sustained write performance.

### What is the TBW endurance of the Plextor M8Se 256GB?

The M8Se 256GB is rated at 220 TBW (Terabytes Written), covered by a three-year limited warranty. At a typical consumer workload of 20 to 40 GB of writes per day, it would take roughly 15 to 30 years to exhaust the endurance rating. This is adequate for mainstream desktop use.

### How does the Plextor M8Se compare to the Intel SSD 600p?

Both are entry-level PCIe 3.0 NVMe SSDs from the same era. The Intel 600p uses an Intel-branded Silicon Motion controller with Intel 3D TLC NAND. The M8Se uses the Marvell 88SS1093 with Toshiba planar TLC. Performance is comparable — both deliver NVMe-level reads with modest writes. Neither is a top performer, but both are adequate upgrades from SATA.

### Does the Plextor M8Se 256GB work in a laptop?

The bare M8SeGN (M.2 without heatspreader) works in any laptop with an M.2 NVMe slot. The M8SeG variant with the factory heatspreader may not fit in some thin laptops due to the added height. In those cases, the heatspreader can be removed, though doing so may affect warranty coverage.
