# Corsair MP600 Pro 4TB Review — Gen4 NVMe SSD (2026)

The Corsair MP600 Pro 4 TB is the range-topping capacity of Corsair's Phison E18-powered PCIe 4.0 NVMe line, offering 3,000 TBW endurance and 6,850 MB/s writes that outpace the smaller capacities.

Quick answer: Power users who need 4 TB of fast Gen4 storage in a single M.2 slot — game libraries, video editing scratch disks, or dual-boot setups — will find the Corsair MP600 Pro 4 TB one of the few options that combines both high capacity and PCIe 4.0 throughput. Those who prioritise raw performance over capacity should consider the 2 TB variant instead, which posts slightly higher write IOPS and has more independent benchmark data available. For users who need 4 TB but can accept slower writes and lower endurance, the Corsair MP600 Core 4 TB (QLC-based) is the budget alternative. Overall, the MP600 Pro 4 TB fills a genuine niche where few competitors operate.

## Performance

The 4 TB model is rated for up to 7,000 MB/s sequential read and 6,850 MB/s sequential write — the highest write speed in the MP600 Pro range, benefiting from the fully populated NAND layout. Random performance is rated at up to 650,000 read IOPS and 700,000 write IOPS. These figures are modestly higher than the 2 TB's 660K/800K for reads and writes, though the write IOPS are slightly lower — likely a consequence of managing twice the NAND density.

Independent reviews of the 4 TB model are scarce; most outlets tested the 1 TB and 2 TB variants. Based on the common Phison E18 platform, the 4 TB is expected to share the same characteristics: a relatively small SLC cache (likely around 150-200 GB on the 4 TB), direct-to-TLC writes at roughly 1,500-2,000 MB/s after cache exhaustion, and thermal throttling that begins at 68 °C. The included heatsink should manage thermals adequately in a desktop with reasonable airflow. For sustained-write scenarios like 4K video capture or large dataset transfers, the 4 TB's larger SLC cache pool is an advantage over the smaller capacities.

## Endurance, TBW & Warranty

Corsair covers the MP600 Pro 4 TB with a five-year limited warranty, capped at 3,000 TBW — whichever is reached first. At Corsair's typical usage figure of 35 GB of writes per day, the drive would take roughly 235 years to exhaust its endurance. Even at a heavy 200 GB/day workload — realistic for a 4 TB drive used as a video editing scratch disk or NAS cache — the drive would last approximately 41 years before hitting the TBW limit. The 1.8 million hour MTBF is a population-level reliability metric, not a guarantee for any individual unit. Corsair's SSD Toolbox provides SMART data and firmware update capability. The five-year warranty length is standard for this tier, matching the Samsung 980 Pro and WD Black SN850.

## Pros and Cons

**Pros:**

- 7,000/6,850 MB/s sequential read/write — fastest in range
- 3,000 TBW endurance for long-term confidence
- 4 TB capacity on a single M.2 2280 module
- Bundled aluminum heatsink included
- AES 256-bit hardware encryption
- 5-year warranty
**Cons:**

- Double-sided PCB limits laptop compatibility
- Few independent reviews for 4 TB specifically
- Write IOPS (700K) slightly lower than 2 TB (800K)
- Thermal throttle at 68 °C is aggressive for dense PCB
- Limited 4 TB PCIe 4.0 competitors for price comparison


## Verdict

Power users who need 4 TB of fast Gen4 storage in a single M.2 slot — game libraries, video editing scratch disks, or dual-boot setups — will find the Corsair MP600 Pro 4 TB one of the few options that combines both high capacity and PCIe 4.0 throughput. Those who prioritise raw performance over capacity should consider the 2 TB variant instead, which posts slightly higher write IOPS and has more independent benchmark data available. For users who need 4 TB but can accept slower writes and lower endurance, the Corsair MP600 Core 4 TB (QLC-based) is the budget alternative. Overall, the MP600 Pro 4 TB fills a genuine niche where few competitors operate.

## Frequently Asked Questions

### Is the Corsair MP600 Pro 4 TB good for gaming?

Yes. The MP600 Pro 4 TB delivers PCIe 4.0 throughput well beyond what current game engines can utilise, so load times will be indistinguishable from any other Gen4 NVMe. The real advantage of the 4 TB model for gaming is sheer capacity — it can hold dozens of large AAA titles without needing a secondary drive. The 650K random read IOPS is sufficient for gaming workloads, though slightly lower than the 2 TB's 660K.

### Is the Corsair MP600 Pro 4 TB compatible with the PS5?

Yes, with a heatsink swap. The 4 TB model has a double-sided M.2 2280 PCB that fits within Sony's M.2 slot dimensions, and its 7,000 MB/s read speed exceeds Sony's 5,500 MB/s recommendation. The included aluminum heatsink is too tall for Sony's M.2 bay (max 11.25 mm with heatsink), so you will need to remove it and install a low-profile aftermarket heatsink.

### Does the Corsair MP600 Pro 4 TB have a DRAM cache?

It does. The drive includes a SK Hynix DDR4 DRAM chip dedicated to the FTL (Flash Translation Layer) mapping table — a full DRAM implementation, not HMB (Host Memory Buffer). With 4 TB of NAND to manage, the DRAM cache is essential for maintaining consistent random write performance across the full address space.

### What is the TBW endurance of the Corsair MP600 Pro 4 TB?

The 4 TB model is rated at 3,000 TBW (Terabytes Written), which is Corsair's highest endurance rating in the MP600 Pro range. At Corsair's typical usage figure of 35 GB of writes per day, the drive would take roughly 235 years to reach the TBW limit. Even at 200 GB/day — a heavy workload for video editors or content creators — it would take approximately 41 years. The warranty is five years, so endurance is a non-concern.

### How does the 4 TB compare to the 2 TB Corsair MP600 Pro?

The 4 TB has higher sequential writes (6,850 vs 6,550 MB/s) and more than double the endurance (3,000 vs 1,400 TBW). However, the 4 TB has slightly lower write IOPS (700K vs 800K) — managing twice the NAND density has a small overhead. Both use the same Phison E18 controller and Micron 96L TLC. The 4 TB is double-sided while the 2 TB may also be double-sided, so neither is ideal for thin laptops. For most users, the 2 TB hits a better price-to-performance ratio; the 4 TB is for those who genuinely need the capacity.

### Does the Corsair MP600 Pro 4 TB work in a laptop?

Probably not. The 4 TB model uses a double-sided PCB with NAND packages on both sides of the M.2 module. Many laptops — especially thin-and-light models — only have clearance for single-sided M.2 drives. Check your laptop's specifications before purchasing. Desktop motherboards and the PS5 have no such limitation, provided the M.2 slot supports PCIe 4.0 x4.
