Intel SSD 670P 2TB QLC NVMe Review (2026)
The Intel 670P 2TB is the flagship capacity of Intel's QLC NVMe line, pairing 144-layer QLC flash with the SM2265G controller for read speeds that rival mainstream TLC drives and enough endurance for serious daily use.

Controller & Memory
The 670P 2 TB uses the Silicon Motion SM2265G controller paired with Intel's 144-layer 1 Tbit 3D QLC NAND. A 256 MB Nanya DDR3L DRAM chip handles the flash translation layer. Intel packages the 2 TB capacity into just two NAND packages on a single-sided M.2 2280 PCB, thanks to high-density die stacking.
This is the capacity where the 670P hits its full stride: 3,500 MB/s sequential reads, 2,700 MB/s writes, 310,000 random read IOPS, and 340,000 random write IOPS. Endurance is rated at 740 TBW, and the variable SLC cache scales from 24 GB minimum up to 280 GB on a mostly empty drive. These numbers are all significant improvements over the 660P.
The 2 TB 670P competes with high-capacity QLC drives like the Crucial P3 2 TB and Samsung 870 QVO 2 TB, as well as mainstream TLC NVMe drives like the Kingston KC2500 2 TB. For users who need bulk NVMe storage on a budget, the 670P offers a compelling cost-per-GB ratio with read performance that matches many TLC drives.

670P Performance & Benchmarks
At 3,500 MB/s sequential reads and 2,700 MB/s writes, the 2 TB 670P effectively saturates the PCIe 3.0 x4 interface. These numbers are nearly identical to mainstream TLC NVMe drives, a testament to how far QLC has come since the 660P. Random IOPS reach 310,000 reads and 340,000 writes, both strong figures.

AnandTech tested the 2 TB model extensively and found it competitive with TLC drives in real-world trace benchmarks when the SLC cache was available. The review noted that the 670P \"owes most of its improved performance to the upgraded SSD controller\" -- the SM2265G's faster interface to the flash eliminates the 2.4 GB/s bottleneck that limited the older SM2263.
The QLC limitation persists under sustained writes. Once the 280 GB SLC cache is exhausted on a full drive (minimum cache: 24 GB), write speed drops to native QLC rates. For typical consumer workloads with idle periods, this is rarely encountered. For users who regularly write hundreds of gigabytes in one session, a TLC drive is still the better tool.

Compare with rival drives:
Endurance, TBW & Warranty
Intel rates the 670P 2 TB at 740 TBW over its 5-year warranty, which equates to roughly 405 GB of writes per day. At 0.2 drive writes per day, this is a significant improvement over the 660P's 400 TBW at the same capacity and approaches the endurance class of mainstream TLC drives. A typical consumer writing 30 to 50 GB daily would need decades to reach this limit. Warranty service goes through Intel's standard RMA process.

Verdict: Is the 670P Worth It in 2026?
The Intel 670P 2TB is the best capacity in Intel's QLC lineup and the one that makes the most sense for budget-focused buyers who need bulk storage. Read speeds match mainstream TLC NVMe drives, the 740 TBW endurance is generous, and the 2 TB capacity handles OS, applications, and a large game library in one drive. The QLC write penalty after cache exhaustion is the main compromise. Against TLC alternatives like the Kingston KC2500 2 TB, the 670P wins on price per GB but loses on sustained write consistency. Choose based on workload: read-heavy users will not notice the QLC trade-off.
