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.
Controller & Memory
Plextor released the M8Se series in 2017 as its mainstream NVMe lineup. The 1TB model uses a Marvell Eldora controller paired with Toshiba MLC NAND, delivering 2,400 MB/s sequential reads and 1,000 MB/s writes. These speeds were competitive at launch but sit in the lower tier of PCIe 3.0 drives by current standards.
The MLC NAND provides consistent write performance without relying on a pseudo-SLC cache. MLC writes at its native speed all the time, meaning there is no burst-to-sustained performance cliff that affects modern TLC drives. The trade-off is lower peak write speeds compared to TLC drives that use aggressive SLC caching.
The 1TB capacity carries a 500 TBW endurance rating with a 3-year warranty. The M.2 2280 form factor fits standard NVMe slots. The M8Se is also available in an add-in card (AIC) form factor for systems without M.2 support. The drive competes with other early Gen3 drives like the Samsung 960 EVO and Intel 600p.

M8Se Series Performance & Benchmarks
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.

- Kingston KC2000 1 TB: 3,200 MB/s read, 2,200 MB/s write
- Kingston KC2000 2 TB: 3,200 MB/s read, 2,200 MB/s write
- Plextor M9Pe Series 512 GB: 3,200 MB/s read, 2,000 MB/s write
- Plextor M9Pe Series 1 TB: 3,200 MB/s read, 2,100 MB/s write
- Plextor M8Se Series 1 TB (this drive): 2,400 MB/s read, 1,000 MB/s write
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.

Verdict: Is the M8Se Series Worth It in 2026?
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.
+ Pros
