# Corsair Neutron NX500 800GB PCIe NVMe SSD (2026)

The Corsair Neutron NX500 800 GB doubles the capacity and endurance of the 400 GB model, packing Toshiba 15nm MLC NAND and 2 GB of DRAM behind a custom heatsink on a PCIe add-in card with 1,396 TBW endurance.

Quick answer: The Corsair Neutron NX500 800 GB is a thermally unconstrained MLC NVMe SSD that sustains its rated performance under heavy workloads where M.2 drives throttle to a fraction of their speed. Desktop users who regularly move large files or run write-intensive applications will benefit most from the add-in card design with its custom heatsink. Those who need M.2 compatibility for compact builds should look at the Samsung 960 Pro or Corsair Force MP500 instead. The NX500 800 GB trades M.2 convenience for thermal headroom and MLC endurance, and it delivers on that trade convincingly.

## Performance

Corsair rates the Neutron NX500 800 GB at 2,800 MB/s sequential read and 1,600 MB/s sequential write, with up to 300,000 random read IOPS and 270,000 random write IOPS. These figures are identical to the 400 GB model, as the Phison E7 controller and Toshiba MLC NAND deliver the same throughput regardless of capacity on this platform.

Where the 800 GB differs is in sustained write capacity and headroom. The larger NAND array and 2 GB DRAM buffer handle mixed workloads with more overhead than the 400 GB model. Independent reviewers at TechSpot showed the NX500 platform never exceeded 49 degrees Celsius during a 100 GB sustained transfer test, compared to 90 degrees and heavy throttling on the Samsung 960 Evo under the same conditions. The NX500 was more than twice as fast as the 960 Evo for writes exceeding 20 GB. For short burst transfers under 3 GB, performance is competitive with other PCIe 3.0 NVMe drives. The drive maintains this thermal advantage consistently across all workload types, from small random reads to large sequential writes, making it one of the most reliable performers under sustained load.

## Endurance, TBW & Warranty

Corsair backs the Neutron NX500 800 GB with a five-year limited warranty, ending at 1,396 TBW of writes or the warranty period, whichever comes first. The 1,396 TBW rating equates to approximately 1 DWPD (drive write per day) over five years, matching the 400 GB model on a proportional basis. At a typical 20 GB per day consumer workload, the endurance translates to roughly 191 years of use. The MLC NAND, heavy overprovisioning, and generous 2 GB DRAM cache all contribute to the sustained endurance performance. The five-year warranty is an upgrade from the earlier MP500 M.2 line, which carried only three-year coverage.

## Pros and Cons

**Pros:**

- Large heatsink eliminates thermal throttling
- 1,396 TBW endurance with MLC NAND
- 2 GB DDR3 DRAM cache
- Sustained writes stay fast past 100 GB
- Toshiba 15nm MLC for reliability
- 5-year warranty coverage
**Cons:**

- PCIe add-in card requires spare slot
- Not M.2, no laptop compatibility
- 2,800 MB/s reads below Samsung 960 Pro
- Premium pricing for the capacity
- 800 GB not a standard capacity size


## Verdict

The Corsair Neutron NX500 800 GB is a thermally unconstrained MLC NVMe SSD that sustains its rated performance under heavy workloads where M.2 drives throttle to a fraction of their speed. Desktop users who regularly move large files or run write-intensive applications will benefit most from the add-in card design with its custom heatsink. Those who need M.2 compatibility for compact builds should look at the Samsung 960 Pro or Corsair Force MP500 instead. The NX500 800 GB trades M.2 convenience for thermal headroom and MLC endurance, and it delivers on that trade convincingly.

## Frequently Asked Questions

### Is the Corsair Neutron NX500 800GB good for gaming?

The NX500 800 GB handles gaming well with 2,800 MB/s reads and 300K random read IOPS. The 800 GB capacity provides ample room for an OS and large game library. The thermal advantage shows during extended gaming sessions with frequent asset loading, where the heatsink prevents any performance degradation. TechSpot measured an 8.1-second Call of Duty level load time, faster than the Samsung 960 Evo at 8.4 seconds.

### What is the TBW endurance of the Corsair Neutron NX500 800GB?

The NX500 800 GB is rated for 1,396 TBW (terabytes written) over its five-year warranty period. This equates to approximately 1 drive write per day over five years. At a typical 20 GB per day consumer workload, the endurance translates to roughly 191 years of use. The 1,396 TBW is double the 400 GB model, maintaining the same 1 DWPD ratio. The MLC NAND and heavy overprovisioning make this one of the most durable consumer NVMe SSDs at this capacity.

### Does the Corsair Neutron NX500 800GB have a DRAM cache?

Yes, the NX500 800 GB includes 2 GB of Nanya DDR3 DRAM for the flash translation layer. This is double the DRAM on the 400 GB model and well above the typical allocation for an 800 GB drive. The large DRAM cache supports the heavy overprovisioning strategy and helps the Phison E7 controller manage the flash translation tables efficiently during sustained write operations.

### How does the Corsair Neutron NX500 compare to the Samsung 960 Pro?

Both are premium NVMe SSDs, but with different approaches. The Samsung 960 Pro uses MLC NAND in an M.2 form factor with higher peak sequential speeds (3,500/2,100 MB/s vs 2,800/1,600 MB/s). The NX500 uses a PCIe add-in card with a large heatsink that prevents thermal throttling during sustained writes, where the Samsung 960 Pro can throttle. The NX500 offers higher endurance at 1,396 TBW versus the Samsung 512 GB at 800 TBW. The Samsung is faster for bursts; the NX500 is more consistent for sustained workloads.

### Why does the Corsair Neutron NX500 use an add-in card form factor?

The HHHL PCIe add-in card allows Corsair to mount a large aluminum heatsink directly to the controller, which keeps temperatures below 49 degrees Celsius under sustained load. M.2 drives run much hotter because they lack meaningful cooling surface area, often throttling at 80-90 degrees during long writes. The NX500 targets desktop users who need sustained write performance without thermal throttling and have a spare PCIe x4 slot available.

### Is the Corsair Neutron NX500 good for video editing?

The NX500 is well-suited for video editing workloads that involve sustained file transfers, thanks to the thermally unconstrained design. The heatsink keeps the drive cool during long render exports and media file moves. The 2,800/1,600 MB/s throughput handles most video editing workflows, though it falls below the Samsung 960 Pro for short burst transfers. The 1,396 TBW endurance means the drive can handle heavy write workloads for years without approaching the warranty ceiling.
