# Corsair Force MP400 1TB NVMe SSD Review (2026)

The Corsair Force MP400 1 TB is a QLC-based NVMe that trades endurance for capacity density, using a Phison E16 controller to hit 3,480 MB/s reads in a single-sided M.2 2280 design.

Quick answer: Gamers and general desktop users who want a responsive NVMe boot drive with room for a large game library will find the Corsair Force MP400 1 TB serviceable, especially where the PCIe 4.0 interface is needed. Anyone doing frequent large-file workloads like video editing or disk imaging should skip it in favor of a TLC drive such as the Samsung 970 EVO Plus or WD Blue SN570, both of which sustain writes far better after the SLC cache fills. The MP400 1 TB is a capable QLC NVMe with competitive burst reads, but its low write endurance and steep post-cache slowdown make it a situational pick rather than a universal recommendation.

## Performance

Corsair rates the Force MP400 1 TB at 3,480 MB/s sequential read and 1,880 MB/s sequential write. Random performance comes in at up to 190,000 read IOPS and 470,000 write IOPS. These are burst figures captured through the drive's dynamic SLC cache, which spans roughly one-quarter of the available NAND space.

On the 1 TB model the SLC cache covers about 250 GB of writes. Once that buffer fills, write speeds drop to the native QLC write speed, which independent reviewers consistently find falls to around 80 to 160 MB/s depending on the workload composition. For a boot drive or game library where sustained writes rarely exceed a few dozen gigabytes, the cache hides the QLC penalty effectively. For anyone regularly moving large video files or disk images exceeding 250 GB, the post-cache slowdown becomes very noticeable. The E16 controller keeps random read responsiveness competitive with TLC alternatives, so OS and application loading feel identical to faster-rated TLC drives in everyday desktop use. The QLC penalty is primarily a sustained-write concern, not a read-performance issue.

## Endurance, TBW & Warranty

Corsair backs the Force MP400 1 TB with a five-year limited warranty, terminated by either the warranty period or 200 TBW of writes, whichever comes first. The 200 TBW endurance rating is modest: at a typical 20 GB of writes per day, the drive would take over 27 years to exhaust its rated write budget, which is comfortable for a consumer gaming or general-use scenario. For heavier workloads involving frequent large file transfers, the budget tightens considerably compared to TLC drives in the same capacity class, which often carry 600 TBW ratings. The MP400 includes Phison's SmartECC third-generation LDPC error correction, SmartRefresh for periodic block refresh, and end-to-end data protection. The drive also ships factory-overprovisioned by approximately 9 percent, which helps maintain consistent performance and reliability over its service life.

## Pros and Cons

**Pros:**

- 3,480 MB/s sequential read speed
- Single-sided M.2 2280 PCB design
- PCIe 4.0 x4 backwards-compatible to 3.0
- Available up to 8 TB in the series
- 5-year warranty included
- Phison E16 with DRAM cache buffer
**Cons:**

- Only 200 TBW endurance rating
- 1,880 MB/s writes well below 2 TB model
- QLC slowdown after SLC cache fills
- No AES 256 hardware encryption
- 190K random read IOPS below TLC rivals


## Verdict

Gamers and general desktop users who want a responsive NVMe boot drive with room for a large game library will find the Corsair Force MP400 1 TB serviceable, especially where the PCIe 4.0 interface is needed. Anyone doing frequent large-file workloads like video editing or disk imaging should skip it in favor of a TLC drive such as the Samsung 970 EVO Plus or WD Blue SN570, both of which sustain writes far better after the SLC cache fills. The MP400 1 TB is a capable QLC NVMe with competitive burst reads, but its low write endurance and steep post-cache slowdown make it a situational pick rather than a universal recommendation.

## Frequently Asked Questions

### Is the Corsair Force MP400 1TB good for gaming?

Yes, for typical gaming workloads the MP400 1 TB performs well. Game loading is dominated by random reads, where the drive stays responsive even with QLC NAND. The 3,480 MB/s burst read speed and 190K random read IOPS are more than sufficient for any current title. The only scenario where the QLC NAND becomes a liability is sustained large-file writing, such as downloading and decompressing game installs over 100 GB at once.

### Is the Corsair Force MP400 1TB compatible with the PS5?

The MP400 1 TB meets Sony's published PS5 requirements on paper: it is an M.2 2280 NVMe SSD with PCIe 4.0 x4 support and a single-sided PCB that fits the 11.25 mm height limit with an added heatsink. The 3,480 MB/s read speed exceeds Sony's 5,500 MB/s recommendation for PCIe 4.0 drives, though the PS5 will run it at PCIe 4.0 speeds in its PCIe 4.0 slot. Sony does not list the MP400 specifically on its compatibility page, but the drive meets the published specifications.

### Does the Corsair Force MP400 have a DRAM cache?

Yes, the MP400 uses a Nanya DDR3L DRAM chip for its flash translation layer. However, the DRAM-to-NAND ratio is half the typical 1 MB per 1 GB standard, which means the controller likely uses some form of FTL table compression. The drive also employs a dynamic SLC cache spanning roughly one-quarter of the SSD's available space to accelerate burst writes before falling back to native QLC speed.

### What is the TBW endurance of the Corsair Force MP400 1TB?

The MP400 1 TB is rated for 200 TBW (terabytes written) over its five-year warranty period. At a typical consumer write workload of 20 GB per day, this translates to roughly 27 years before hitting the rated endurance ceiling. The endurance is low relative to TLC-based competitors, which commonly offer 600 TBW at the same 1 TB capacity, because QLC NAND inherently handles fewer program-erase cycles per cell.

### How does the Corsair Force MP400 1TB compare to the Samsung 970 EVO Plus 1TB?

The Samsung 970 EVO Plus uses TLC NAND and offers 3,500/3,300 MB/s read/write speeds versus the MP400's 3,480/1,880 MB/s. The Samsung sustains writes far better after cache exhaustion and carries a 600 TBW endurance rating, triple the MP400's 200 TBW. The MP400 matches the Samsung on burst reads and is backwards-compatible with PCIe 4.0 slots, but the Samsung is the stronger all-around pick for write-heavy workloads.

### Does the Corsair Force MP400 need a heatsink?

No heatsink is included with the MP400. The Phison E16 controller implements thermal throttling that gradually reduces performance above 80 degrees Celsius, and the drive supports ASPM and APST power management to keep idle thermals low. For desktop use, motherboard M.2 heatsinks are generally sufficient. For PS5 installation, an aftermarket heatsink is recommended to stay within Sony's dimensional limits.

### Is the 1TB MP400 slower than the 2TB and 4TB models?

Yes, the 1 TB model is noticeably slower on writes and random IOPS compared to larger capacities. The 1 TB writes at 1,880 MB/s versus 3,000 MB/s on the 2 TB, and manages 190K/470K random IOPS versus the 4 TB's 610K/710K. The 1 TB and 2 TB use the Phison E16 PCIe 4.0 controller, while the 4 TB and 8 TB switch to the Phison E12S on PCIe 3.0. The trade-off is that the 1 TB is single-sided and fits thin laptops.
