Corsair MP600 Core 4TB — High-Capacity QLC NVMe SSD
The Corsair MP600 Core 4 TB is the flagship of Corsair's QLC PCIe 4.0 lineup, using dense Micron 96-layer NAND and the Phison E16 controller to deliver near-TLC performance at the highest capacity the series offers.
The 4 TB MP600 Core packs eight Micron 96L QLC NAND packages and 2 GB of SK Hynix LPDDR4 DRAM onto a double-sided M.2 2280 PCB, all under the same gunmetal aluminum heatsink found on the smaller capacities. The Phison PS5016-E16 8-channel controller leverages the massive NAND die count for the best performance in the Core series — 4,950 MB/s reads and 3,950 MB/s writes are within striking distance of early TLC PCIe 4.0 drives.
A double-sided PCB means this drive may not fit in some ultra-thin laptops or single-sided-only M.2 slots; check your system's clearance before buying. For desktops and the PS5, thickness is the more relevant constraint, and the factory heatsink adds roughly 7 mm of height. Also available in 1 TB and 2 TB variants, both with lower write speeds and endurance.
At 4 TB, the QLC architecture starts working in its favor. More NAND die means deeper write queues, larger pseudo-SLC caches (the 4 TB model can allocate significantly more space to the write cache), and higher sustained writes before the QLC cliff hits. The main competitors at this capacity are the Sabrent Rocket Q4 4 TB (same Phison E16 + QLC platform) and the Crucial P3 Plus 4 TB (DRAM-less QLC, PCIe 4.0). TLC alternatives at 4 TB, like the Samsung 990 Pro 4 TB, command a significant price premium.
✅ Storage Comparisons:
🚀 Performance and benchmarks
The MP600 Core 4 TB leads its siblings with 4,950 MB/s sequential reads, 3,950 MB/s sequential writes, 630K random read IOPS, and 580K random write IOPS. These are the best numbers in the Core lineup and represent what the Phison E16 platform can achieve when given maximum NAND parallelism. AnandTech's testing of the 4 TB Sabrent Rocket Q4 — an identical platform — found that the large SLC cache on high-capacity QLC drives can absorb over 100 GB of writes before exhausting, after which speeds settle to QLC-native levels around 80–150 MB/s depending on the workload.

- PNY XLR8 CS3140 1 TB: 7,500 MB/s read, 5,650 MB/s write
- PNY XLR8 CS3140 2 TB: 7,500 MB/s read, 6,850 MB/s write
- Asgard AN4 512 GB: 7,500 MB/s read, 5,500 MB/s write
- Asgard AN4 1 TB: 7,500 MB/s read, 5,500 MB/s write
- Corsair MP600 Core 4 TB (this drive): 4,950 MB/s read, 3,950 MB/s write
The real-world implication is that the 4 TB model is the only MP600 Core variant where QLC does not feel like a compromise for most users. Game loads, application launches, and typical desktop tasks are indistinguishable from TLC PCIe 4.0 drives. Even moderate file transfers stay within the SLC cache. Only sustained writes exceeding 100 GB — think cloning a full drive or exporting hours of 4K video — will trigger the QLC cliff, and even then the larger cache delays it significantly compared to the 1 TB model.
🖥️ Endurance and warranty
Corsair rates the MP600 Core 4 TB at 800 TBW endurance with a five-year limited warranty. At 800 TBW, you can write approximately 438 GB per day for five years before reaching the rated limit. For a 4 TB drive used primarily as a game library and media storage — where most operations are reads — this is more than sufficient. The 1.7 million hour MTBF figure matches the rest of the Core series. Corsair's SSD Toolbox software provides S.M.A.R.T. health data, estimated remaining endurance, and firmware update capability. Warranty claims go through Corsair's online portal; the drive must be registered for the full five-year coverage.

Conclusion
The Corsair MP600 Core 4 TB is the capacity where QLC PCIe 4.0 starts to justify itself. The 3,950 MB/s writes, 630K random read IOPS, and a large pseudo-SLC cache make this the most consistent performer in the Core lineup. Add 800 TBW endurance and a five-year warranty, and it becomes a strong contender for a high-capacity game library or media drive. The catch is the double-sided PCB, which rules out some laptops and single-sided M.2 slots. If your system can accommodate it, and you value capacity and price-per-GB over absolute peak write speed, the MP600 Core 4 TB is a practical alternative to pricier TLC options like the Samsung 990 Pro 4 TB. Content creators who constantly write large files should still lean toward TLC; everyone else will find little reason to pay more.
