# Intel 670P 512GB — Third-Gen QLC NVMe SSD (2026)

The Intel 670P 512GB is Intel's third-generation QLC NVMe drive, offering dramatically better performance than the 660P thanks to 144-layer QLC NAND and the Silicon Motion SM2265G controller.

Quick answer: The Intel 670P 512GB is a significant improvement over the 660P and one of the better QLC NVMe drives available. Its 3,500 MB/s read speed is competitive with TLC Gen3 drives, and the 5-year warranty provides peace of mind. The single-sided design is ideal for laptop upgrades. If you need better sustained write performance or higher endurance, the Samsung 970 EVO Plus 500GB (TLC, 300 TBW) is a better choice. For a budget NVMe drive with good read performance and laptop-friendly form factor, the 670P is a solid option.

## Performance

The Intel 670P 512GB is rated at up to 3,500 MB/s sequential reads and 2,700 MB/s sequential writes, with random performance up to 310K read IOPS and 340K write IOPS. These represent a generational leap over the 660P (1,800/1,800 MB/s) and 665P (2,000/2,000 MB/s), bringing QLC performance into TLC territory for typical consumer workloads.

Independent reviews at AnandTech, Tom's Hardware, PCMag, and StorageReview confirmed the 670P's competitive sequential performance. In real-world use, the 670P feels much faster than the 660P and approaches TLC Gen3 performance for typical consumer workloads including OS boot, application launches, and game loading.

The dynamic SLC cache handles burst writes well, scaling from 6GB to 70GB depending on free space. Once the cache exhausts during sustained large-file writes, throughput drops to approximately 320 MB/s — better than the 660P's ~100-150 MB/s but still noticeably slower than TLC drives. For typical consumer workloads, the cache rarely exhausts. The limitation shows up during large file transfers exceeding the cache size.

The 670P's single-sided design is a practical advantage for laptop compatibility. All capacities fit on one side of the PCB, making the drive compatible with thin-and-light laptops that only accept single-sided M.2 modules.

## Endurance, TBW & Warranty

Intel backs the 670P 512GB with a 5-year limited warranty and a 185 TBW endurance rating. At 30 GB of writes per day, that is roughly 16 years of theoretical endurance. The 185 TBW is lower than TLC competitors like the Samsung 970 EVO Plus 500GB (300 TBW) but typical for a QLC drive. Intel's warranty is handled through their support portal.

## Pros and Cons

**Pros:**

- 3,500 MB/s reads — near the PCIe 3.0 x4 ceiling
- 144-layer QLC NAND — major upgrade over 660P/665P
- 5-year warranty
- Single-sided PCB fits thin laptops
- Competitive price for QLC NVMe
**Cons:**

- 185 TBW endurance — lower than TLC competitors
- Sustained write speed drops to ~320 MB/s after cache
- QLC NAND limits write-heavy workloads
- 512GB capacity may be limiting for some users


## Verdict

The Intel 670P 512GB is a significant improvement over the 660P and one of the better QLC NVMe drives available. Its 3,500 MB/s read speed is competitive with TLC Gen3 drives, and the 5-year warranty provides peace of mind. The single-sided design is ideal for laptop upgrades. If you need better sustained write performance or higher endurance, the Samsung 970 EVO Plus 500GB (TLC, 300 TBW) is a better choice. For a budget NVMe drive with good read performance and laptop-friendly form factor, the 670P is a solid option.

## Frequently Asked Questions

### Does the Intel 670P have DRAM?

Yes. The 670P 512GB has 256MB of Nanya DDR3L DRAM for FTL mapping. This helps maintain consistent random I/O performance and is an improvement over the DRAM-less budget QLC drives that rely on HMB.

### Is the Intel 670P good for gaming?

Yes. The 670P 512GB delivers 3,500 MB/s reads and 2,700 MB/s writes, which is competitive with TLC Gen3 drives for gaming. Game loads are fast, and the SLC cache handles game installs well. It is a good budget gaming NVMe drive, especially for laptop upgrades thanks to the single-sided design.

### What is the TBW endurance of the 670P 512GB?

Intel rates the 670P 512GB at 185 TBW. This is lower than TLC competitors but typical for a QLC drive. The 1TB model is rated at 370 TBW and the 2TB at 740 TBW. At 30 GB of writes per day, the 512GB model would last roughly 16 years.

### How does the 670P compare to the 660P?

The 670P is dramatically faster than the 660P: 3,500/2,700 MB/s vs 1,800/1,800 MB/s. The 144-layer QLC NAND and SM2265G controller in the 670P provide a massive performance improvement over the 660P's 64-layer QLC and older controller. The 670P is the much better drive.

### How does the 670P compare to the Samsung 970 EVO Plus?

The Samsung 970 EVO Plus 500GB offers higher endurance (300 TBW vs 185 TBW) and better sustained write performance thanks to TLC NAND. Sequential read speeds are similar. The 670P is typically cheaper, making it the better budget option, while the Samsung is the better long-term investment for write-heavy workloads.
