# Corsair MP600 Pro LPX 4 TB PS5 SSD Review (2026)

The Corsair MP600 Pro LPX 4 TB is the PS5-focused member of Corsair's Phison E18 line, pairing full 7,100 MB/s Gen4 throughput with 3,000 TBW of endurance and a pre-installed low-profile heatsink.

Quick answer: The Corsair MP600 Pro LPX 4 TB is the right pick for buyers who want a turnkey PlayStation 5 expansion that clears Sony's clearance and speed requirements out of the box, or a desktop 4 TB NVMe where the included heatsink saves a separate heatsink purchase. Skip it for a laptop, where the double-sided 4 TB PCB and the permanent heatsink will not fit, and skip it on a motherboard whose M.2 slots all sit under non-removable shrouds. The closest alternative is the WD Black SN850X 4 TB, which trades the bundled heatsink for slightly higher peak reads and a shorter 2,400 TBW rating, while the Samsung 990 Pro 4 TB with heatsink is the pick if raw sequentials matter more than cost. We rate the LPX 4 TB a solid, no-surprises Gen4 drive whose value lives entirely in the pre-installed PS5-compatible heatsink, so the premium is worth paying only when that heatsink saves a separate purchase.

## Performance

On the 4 TB MP600 Pro LPX, sequential reads hit 7,100 MB/s and writes reach 6,800 MB/s over a PCIe 4.0 x4 link, with random performance rated at up to 1,000,000 read IOPS and 1,200,000 write IOPS. Those are the full Phison E18 numbers, identical to what the 1 TB and 2 TB LPX deliver, so stepping up to 4 TB buys capacity and endurance rather than extra peak speed.

In daily use the LPX behaves like every well-sorted E18 drive: game load times are indistinguishable from any other top-tier PCIe 4.0 SSD, because the CPU and asset decompression set the pace long before the storage does. The payoff shows up in sequential workloads such as copying a 100 GB project folder, scrubbing 4K footage, or feeding DirectStorage-enabled titles that stream textures straight from the SSD. There the 4 TB's larger pseudo-SLC cache is the real advantage: it absorbs sustained writes at full 6,800 MB/s speed for longer than the smaller capacities before the cache empties and writes drop to the native Micron TLC rate, typically a fraction of the headline number.

Independent reviewers consistently place the E18 plus Micron TLC combination within a few percent of the WD Black SN850X and Samsung 990 Pro on the usual benchmark suites, close enough that the bundled heatsink and street price, not raw sequentials, should decide. The fixed low-profile heatsink does its job: under sustained load the LPX holds its rated speeds without throttling in a well-ventilated bay.

## Endurance, TBW & Warranty

Corsair covers the MP600 Pro LPX 4 TB with a five-year limited warranty that ends early only if the 3,000 TBW endurance rating is exceeded, whichever comes first. That 3,000 TBW figure is the highest in the LPX line, which scales from roughly 700 TBW on the 1 TB through 1,400 TBW on the 2 TB. At a heavy 50 GB of writes per day, a serious content-creation workload, the drive would need around 164 years to wear out the NAND, and even a professional pipeline pushing 200 GB a day would take more than four decades, so in practice the warranty term expires long before the flash does. Corsair rates the drive at 2,000,000 hours MTBF, but treat that as a population-reliability statistic across a large fleet of drives rather than a guarantee that any single unit will run for that long. RMAs are handled through Corsair directly or via the retailer of purchase.

## Pros and Cons

**Pros:**

- 7,100 MB/s reads over PCIe 4.0
- 3,000 TBW endurance, highest in the LPX line
- Pre-installed PS5-compatible low-profile heatsink
- Phison E18 with discrete DRAM cache
- 1.2 million random write IOPS rated
- Five-year warranty, TBW-limited
**Cons:**

- Permanent heatsink will not fit laptop slots
- Double-sided 4 TB PCB restricts thin-laptop use
- Heatsink cannot be removed for motherboard shrouds
- Premium over bare E18 drives without a heatsink
- Peak Gen4 speed is invisible in most current games


## Verdict

The Corsair MP600 Pro LPX 4 TB is the right pick for buyers who want a turnkey PlayStation 5 expansion that clears Sony's clearance and speed requirements out of the box, or a desktop 4 TB NVMe where the included heatsink saves a separate heatsink purchase. Skip it for a laptop, where the double-sided 4 TB PCB and the permanent heatsink will not fit, and skip it on a motherboard whose M.2 slots all sit under non-removable shrouds.

## Frequently Asked Questions

### Is the Corsair MP600 Pro LPX 4 TB good for a PS5?

Yes, this is the LPX's primary design target. Sony recommends an M.2 NVMe SSD with at least 5,500 MB/s sequential reads that fits within roughly 110 by 25 by 11.25 millimetres with a heatsink, and the Corsair MP600 Pro LPX 4 TB clears both comfortably at 7,100 MB/s reads with a heatsink sized for the bay. The 4 TB capacity holds a very large digital game library alongside the console's internal storage, and installation does not affect the PS5 warranty. No separate heatsink purchase is needed, which is the main reason the LPX exists over the bare MP600 Pro XT.

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

The Corsair MP600 Pro LPX 4 TB carries a 3,000 TBW endurance rating, the highest in a lineup that scales from roughly 700 TBW on the 1 TB through 1,400 TBW on the 2 TB. That works out to about 164 years at a heavy 50 GB of writes per day, so the flash will outlast the five-year warranty by a wide margin. The 3,000 TBW figure matters more on the 4 TB because it is the capacity most likely to see sustained write workloads such as video capture or scratch-disk use, and here the endurance headroom is the largest in the family.

### Does the Corsair MP600 Pro LPX 4 TB need a heatsink?

It already has one. The LPX ships with a low-profile aluminium heatsink permanently bonded to the drive, so there is nothing extra to buy for a PlayStation 5 or a typical desktop. That heatsink is the LPX's reason for existing over the bare MP600 Pro XT, and it is sized to clear the PS5 expansion slot's height limit. The fixed heatsink is a drawback too, since it cannot be removed, which rules the drive out for laptops and for desktop motherboards whose M.2 slots sit under non-removable shrouds. Under sustained writes the heatsink keeps the Phison E18 controller from throttling in a well-ventilated bay.

### Can I use the Corsair MP600 Pro LPX 4 TB in a laptop?

In most cases, no. The 4 TB LPX uses a double-sided M.2 2280 PCB, and many thin laptops only accept single-sided drives, so it will not seat in those slots. The permanent low-profile heatsink also adds height that some laptop M.2 bays cannot clear. If your laptop explicitly supports double-sided M.2 2280 NVMe drives and has clearance for a heatsink, the drive will work at its full PCIe 4.0 speed, but verify the laptop specification before buying. For a thin-and-light, the 1 TB LPX is also likely single-sided, though the PCB layout should be confirmed before relying on it for a tight laptop slot, or consider a bare DRAM-less drive without a heatsink.

### How does the Corsair MP600 Pro LPX 4 TB compare to the WD Black SN850X 4 TB?

Both are PCIe 4.0 flagships at 4 TB, but they take different routes. The WD Black SN850X 4 TB posts slightly higher peak reads at 7,300 MB/s versus the LPX's 7,100, against 6,600 MB/s writes for the SN850X versus 6,800 for the LPX, so the two trade blows on sequentials. The LPX pulls ahead on endurance at 3,000 TBW versus the SN850X's 2,400 TBW, and it ships with a PS5-ready low-profile heatsink in the box. The SN850X is the better pick for a bare desktop slot or a laptop, while the LPX is the better pick for a PS5 or a board without its own M.2 cooling.

### Is the Corsair MP600 Pro LPX 4 TB faster than the 2 TB model?

Not in rated sequential or random speed. Both the 4 TB and the 2 TB LPX are rated at 7,100 MB/s reads and 6,800 MB/s writes, and both share the same 1,000,000 random read IOPS and 1,200,000 random write IOPS ratings, since Corsair does not gate throughput behind capacity from 1 TB upward. What the 4 TB adds is double the usable space, endurance raised to 3,000 TBW versus 1,400 TBW on the 2 TB, and a larger pseudo-SLC cache that holds sustained writes at full speed for longer. The reason to choose the 4 TB is capacity and write headroom, not extra peak bandwidth.
