Corsair MP600 Pro NH 4TB: Bulk Flagship Storage (2026)
The Corsair MP600 Pro NH 4TB is a DRAM-equipped PCIe 4.0 flagship rated for 7,000 MB/s reads, offering bulk capacity without a bundled heatsink.
Controller & Memory
The MP600 Pro NH 4TB runs an 8-channel Phison PS5018-E18 controller with Micron 176-layer 3D TLC NAND and onboard DRAM, putting it in Corsair's DRAM-equipped flagship tier rather than the budget or DRAM-less lines. The "NH" designation stands for no heatsink: Corsair sells the same core platform with a heatsink as the MP600 Pro XT, but the NH variant is built bare so it fits thin laptops, small-form-factor cases, and PS5 consoles without clearance issues.
Corsair sells the MP600 Pro NH in 500GB, 1TB, 2TB, 4TB, and 8TB capacities, one of the widest capacity spreads in its flagship lineup. The 4TB matches the 2TB's peak random-IOPS rating at 1,000,000 read and 1,200,000 write, and returns to the line's full 6,500 MB/s sequential write rating that the 2TB rates lower on.
As a single-sided M.2 2280 drive with no bundled heatsink, the MP600 Pro NH 4TB competes against other DRAM-equipped PCIe 4.0 flagships like the Samsung 990 Pro and WD Black SN850X, and against Corsair's own DRAM-less MP600 Elite for buyers deciding whether onboard DRAM is worth the higher price at this capacity. Buyers who already have motherboard M.2 cooling in place, or don't need one at all for a laptop or console install, get the same core Phison E18 platform as the heatsinked MP600 Pro XT without paying for hardware they won't use.

MP600 Pro NH Performance & Benchmarks
The 4TB MP600 Pro NH is rated for 7,000 MB/s sequential reads and 6,500 MB/s sequential writes, with random performance rated at 1,000,000 IOPS reading and 1,200,000 IOPS writing, matching the 2TB's peak rating in this line. As a DRAM-equipped drive, it holds random-access performance more consistently under mixed workloads than DRAM-less rivals, since the onboard DRAM chip handles the flash translation layer's mapping tables directly rather than borrowing system RAM.

- Patriot Viper PV593 4 TB: 14,500 MB/s read, 14,000 MB/s write
- Patriot Viper PV573 2 TB: 14,000 MB/s read, 12,000 MB/s write
- Corsair MP600 Pro NH 4 TB (this drive): 7,000 MB/s read, 6,500 MB/s write
Like other TLC drives, the MP600 Pro NH leans on an SLC write cache to hit its peak write number; once a sustained transfer outruns that cache, throughput drops toward native TLC write speed. At 4TB, large sustained transfers, like archiving a big game library or moving bulk media files, are more likely to outrun the cache than on a smaller drive used for lighter workloads. Corsair doesn't publish the exact cache size for this capacity. For PS5 use, this drive's 7,000 MB/s read rating comfortably clears Sony's 5,500 MB/s minimum, and the no-heatsink design is specifically built to fit the PS5's storage expansion slot.

Endurance, TBW & Warranty
The 4TB MP600 Pro NH carries a 3,000 TBW endurance rating and a full 5-year warranty. At a realistic consumer workload of 30 to 50GB written per day, 3,000 TBW takes roughly 164 to 274 years to exhaust, far beyond the 5-year warranty window and comfortably covering heavier content-creation workloads as well. Corsair's official spec sheet for this capacity does not publish an MTBF figure, so treat any population-level reliability number from third-party listings as an estimate rather than a Corsair-confirmed spec. The 5-year warranty and DRAM-equipped design put this drive on equal footing with flagship rivals from Samsung and WD on paper endurance and coverage terms.

Verdict: Is the MP600 Pro NH Worth It in 2026?
The MP600 Pro NH 4TB suits buyers who want a large, DRAM-equipped flagship for bulk storage or a big game library without a bundled heatsink, especially for thin laptops or PS5 upgrades with tight clearance. Buyers who don't need onboard DRAM and want to save money should consider Corsair's own DRAM-less MP600 Elite instead, which rates similarly on sequential speed at 4TB. Samsung's 990 Pro and WD's Black SN850X remain the closest direct DRAM-equipped rivals, generally with longer independent review histories. For bulk flagship storage with a full 5-year warranty, the MP600 Pro NH 4TB's peak-rated random IOPS and 3,000 TBW endurance make it a strong pick.
