Plextor M10P 2 TB Review: InnoGrit-Powered PCIe 4.0 NVMe (2026)
The Plextor M10P 2 TB is a rare single-sided PCIe 4.0 flagship, pairing InnoGrit's IG5236 controller with Kioxia 96-layer TLC and DDR4 DRAM for some of the strongest real-world results this side of Optane.
Controller & Memory
The Plextor M10P 2 TB runs an eight-channel InnoGrit IG5236 (Rainier) controller rather than the Phison E18 most of its Gen4 rivals use, and that choice is the whole story of this drive. Plextor pairs the IG5236 with Kioxia BiCS4 96-layer TLC NAND, staying loyal to the Kioxia stack after the 2019 Kioxia and Lite-On acquisition, plus a discrete DDR4 DRAM buffer and a pseudo-SLC cache for burst writes. The result, in the hands of both The SSD Review and guru3d, was unusually strong real-world and PCMark numbers that approached Optane-class responsiveness at the time of its 2021 launch. On a PCIe 4.0 x4 link the 2 TB is rated for 7,000 MB/s sequential reads and up to 5,000 MB/s writes, with random performance quoted up to 1,000,000 read and 800,000 write IOPS.
The M10P family spans 512 GB, 1 TB, and this 2 TB, all sharing the same 7,000 MB/s read rating and the same five-year, TBW-limited warranty; what scales with capacity is endurance, at 320, 640, and 1,280 TBW, and write headroom. Plextor ships the platform in three form factors: the bare M10P(GN) for laptops and small-form-factor PCs, the M10P(G) with an anodised aluminium heatsink, and the M10P(Y) HHHL add-in card with RGB lighting and a graphene-treated die-cast heatsink. The standout detail on the 2 TB is the PCB layout: where most 2 TB Gen4 drives are double-sided, Plextor laid the M10P 2 TB out single-sided, which The SSD Review flagged as the first single-sided 2 TB sample it had seen, clearing thin laptops and single-sided slots that block fatter drives.
Compatibility is straightforward Gen4: it drops into any PCIe 4.0 x4 M.2 slot on a recent AMD or Intel desktop, works in the PS5 with the M10P(G) heatsink variant clearing Sony's dimension limits, and the single-sided layout makes it one of the few 2 TB drives that genuinely suits an ultrabook. Against rivals, the Kingston KC3000 2 TB and Sabrent Rocket 4 Plus trade blows on peak speed, but the KC3000's Phison E18 pushes writes to 7,000 MB/s versus the M10P's 5,000, so sequential-write buyers lean Kingston. The Sabrent Rocket 4 Plus shares the InnoGrit IG5236 platform and is the closest architectural sibling. The caveat is availability: Plextor's retail footprint outside Europe and Asia is thin, so street price and stock, not the spec sheet, decide whether the M10P 2 TB is in the running.

M10P Performance & Benchmarks
On the 2 TB Plextor M10P, sequential reads are rated at 7,000 MB/s over the PCIe 4.0 x4 bus, with sequential writes up to 5,000 MB/s and random performance quoted up to 1,000,000 read and 800,000 write IOPS. Those are flagship Gen4 numbers on paper, though the write rating sits below the 7,000 MB/s that Phison E18 rivals like the Kingston KC3000 post, which is the trade-off Plextor made in choosing the InnoGrit platform.

Where the M10P 2 TB punches above its spec sheet is in real-world and trace-based benchmarks. Both The SSD Review and guru3d found the InnoGrit IG5236 paired with Kioxia BiCS4 96-layer TLC delivered some of the best true-data and PCMark results they had recorded short of Optane, with notably low access times that the E18 competition could not always match. That is the actual case for choosing this drive: synthetic peak writes lose to E18 flagships, but application loads, game level transitions, and mixed random workloads feel at least as fast.
Like every TLC drive, the M10P leans on a pseudo-SLC cache that absorbs burst writes at full speed before settling to the native TLC rate once the cache fills. For a boot drive or game library that rarely matters, since the cache almost never exhausts in daily use. The 2 TB's larger NAND pool gives it a deeper cache than the 512 GB and 1 TB models, so sustained workloads like video capture or large project transfers hold peak speed longer before the write curve drops. Plan for a heatsink on a desktop, since the IG5236 runs warm under sustained load, or pick the M10P(G) or M10P(Y) variant with cooling built in.

Endurance, TBW & Warranty
Plextor backs the M10P 2 TB with a five-year limited warranty that ends early if the 1,280 TBW endurance rating is exceeded, whichever comes first. That 1,280 TBW figure scales up the family ladder from 320 TBW on the 512 GB and 640 TBW on the 1 TB, holding roughly 640 TBW per terabyte on the larger dies. At a typical consumer write load of 20 GB per day, the 2 TB drive would need around 175 years to wear out its NAND, and even a heavy 100 GB-per-day creative workflow would take more than three decades, so in practice the five-year term expires long before the flash does. Plextor rates the drive at around 2 million hours MTBF, but treat that as a population-reliability statistic across a large fleet rather than a lifespan guarantee for any single unit. Warranty service runs through Plextor and Kioxia directly, and the drive's thin retail distribution outside Europe and Asia is the more practical support risk than the endurance math.

Verdict: Is the M10P Worth It in 2026?
The Plextor M10P 2 TB is the right pick for buyers who want a single-sided 2 TB PCIe 4.0 drive that fits a thin laptop or a cramped M.2 slot and still posts real-world numbers that hang with the Phison E18 flagships, since the InnoGrit IG5236 plus Kioxia BiCS4 combo earned exactly that reputation in independent testing. Skip it if maximum sequential-write throughput is the goal: the 5,000 MB/s write rating trails the Kingston KC3000 2 TB and its 7,000 MB/s on the same E18-versus-IG5236 split, and PS5 upgraders can get equivalent game-load performance from cheaper drives. The closest architectural peer is the Sabrent Rocket 4 Plus, which rides the same InnoGrit controller and is easier to find in North America. We read the M10P 2 TB as a quietly excellent Gen4 drive whose real weakness is distribution, not engineering, worth it when it is in stock at the right price and easy to pass on when it is not.
