# Plextor M8Se 1TB Review (2026)

The Plextor M8Se 1TB is an early PCIe 3.0 NVMe drive using Toshiba MLC NAND, offering reliable write consistency at the cost of lower peak speeds than newer TLC designs.

Quick answer: The Plextor M8Se 1TB is an early PCIe 3.0 NVMe drive with MLC NAND that provides consistent write performance without cache tricks. The 2,400 MB/s reads are adequate, but the 1,000 MB/s writes trail modern alternatives significantly. Buy it only if found at a steep discount or if you specifically value MLC write consistency.

## Performance

The Plextor M8Se 1TB is rated at 2,400 MB/s sequential reads and 1,000 MB/s sequential writes with 210,000 IOPS random reads and 175,000 IOPS random writes. The 2,400 MB/s read speed is adequate but below the 3,000-3,500 MB/s that later PCIe 3.0 drives achieved. The 1,000 MB/s write speed is the main limitation, trailing modern TLC drives by 2-3x.

The Marvell Eldora controller was a capable design in 2017 but has been surpassed by newer controllers from Phison and Samsung. The MLC NAND is both a strength and a weakness: it provides consistent write performance without SLC cache tricks, but the native MLC write speed of roughly 1,000 MB/s is lower than what modern TLC drives achieve with SLC caching (1,500-3,000 MB/s).

For typical consumer workloads like OS booting, web browsing, and application use, the M8Se delivers a responsive experience that is clearly faster than SATA SSDs. The 2,400 MB/s read speed handles game loading adequately. Where the M8Se falls behind is in large file transfers, where the 1,000 MB/s write speed becomes the bottleneck. Independent reviews at TweakTown and Tom Hardware confirmed these performance characteristics.

## Endurance, TBW & Warranty

Plextor backs the M8Se series with a 3-year warranty. The 1TB model is rated at 500 TBW endurance. Writing 30 GB per day would take over 45 years to reach 500 TBW. The MLC NAND inherently provides better per-cell endurance than TLC, contributing to the solid TBW rating.

The 3-year warranty is shorter than the 5-year coverage offered by newer drives from Samsung, WD, and Crucial. Plextor handles warranty through its regional support network. The drive includes S.M.A.R.T. monitoring and wear-leveling. Given the older design, the M8Se is most likely encountered as a used or surplus drive rather than a new purchase.

## Pros and Cons

**Pros:**

- MLC NAND provides consistent write performance
- 2,400 MB/s reads — 4x faster than SATA
- 500 TBW endurance solid for MLC 1TB
- Available in both M.2 and AIC form factors
**Cons:**

- 1,000 MB/s writes well below modern NVMe drives
- Only 3-year warranty versus 5-year standard
- Marvell controller surpassed by newer designs
- Outperformed by current budget NVMe drives


## Verdict

The Plextor M8Se 1TB is an early PCIe 3.0 NVMe drive with MLC NAND that provides consistent write performance without cache tricks. The 2,400 MB/s reads are adequate, but the 1,000 MB/s writes trail modern alternatives significantly. Buy it only if found at a steep discount or if you specifically value MLC write consistency.

Skip it for any new purchase. Modern TLC drives like the Samsung 970 EVO Plus, WD Black SN750, or even budget options like the Kingston NV2 offer 2-3x faster writes, 5-year warranties, and better overall value. The M8Se is best viewed as a legacy drive that still works fine for basic computing but is outclassed by current offerings.

## Frequently Asked Questions

### Is the Plextor M8Se 1TB good for gaming?

It is adequate for gaming but not ideal. The 2,400 MB/s read speed handles game loading fine, and the 1TB capacity holds 8-10 AAA titles. The MLC NAND ensures consistent read latency. However, game installations and updates will be slower than on modern drives due to the 1,000 MB/s write speed. For budget gaming, newer TLC drives offer better write performance and longer warranties at similar or lower prices. The M8Se works as a gaming drive but has been surpassed.

### Why is the M8Se write speed only 1,000 MB/s?

The M8Se uses Toshiba MLC NAND that writes at its native speed without pseudo-SLC caching. Modern TLC drives use a portion of their flash as high-speed SLC cache, achieving burst writes of 1,500-3,000 MB/s before dropping to native TLC speeds. The MLC approach provides consistent writes from the first byte to the last, but the consistent speed is lower than the burst speed of TLC drives. This is a trade-off between consistency and peak performance.

### Does the Plextor M8Se 1TB have DRAM?

The M8Se controller includes memory for flash translation layer management, though Plextor does not prominently advertise the DRAM specifications. The Marvell Eldora controller is a mature design that supports DRAM caching for mapping tables. In practice, the M8Se random I/O performance (210K/175K IOPS) suggests adequate mapping table resources. For a drive of this era and price point, the caching implementation is appropriate for the performance tier.

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

Both are early PCIe 3.0 NVMe drives from 2017. The Samsung 960 EVO 1TB is rated at 3,200/1,900 MB/s read/write versus the M8Se at 2,400/1,000 MB/s, giving Samsung a significant speed advantage. The Samsung uses TLC NAND with V-NAND technology and a custom controller, while the Plextor uses MLC with a Marvell controller. Samsung offers the Magician software suite. The M8Se has the MLC consistency advantage but lower peak performance. Both have been superseded by newer drives.

### Is the Plextor M8Se compatible with PS5?

Physically it fits the PS5 M.2 slot, but it is not recommended. Sony recommends PCIe 4.0 NVMe drives with 5,500+ MB/s read speeds. The M8Se is PCIe 3.0 at 2,400 MB/s, well below recommendations. The 1TB capacity is adequate for PS5 games, but the performance gap versus recommended drives is substantial. For PS5 expansion, choose a PCIe 4.0 drive like the WD Black SN850X or Samsung 980 Pro with at least 1TB capacity.

### What is the difference between the M8Se and M8Se(Y)?

The M8Se is the standard M.2 2280 version. The M8SeY is the same drive on a PCIe add-in card (AIC) for desktops without M.2 slots. Internally they use identical hardware: the same Marvell Eldora controller, Toshiba MLC NAND, and performance ratings. The AIC version includes a half-height, half-length PCIe bracket and an M.2-to-PCIe adapter board. Choose based on your system available slots. Performance is identical between the two form factors.
