Intel 665P 1Tb SSD technical review

665P (1Tb) produced by Intel works on Silicon Motion SM2263EN. The NVMe SSD write a data location map on Dynamic-Random Access Memory DDR3L to run a games without delays. The 665P comes equipped with Intel 96L 3D QLC flash memory. Internal SSD is offered also in 2 Tb volume sizes.

Performance and benchmarks

NVMe SSD use PCIe M.2 3.0 x 4 computer expansion bus standard with maximum write speeds equals to 2000 MB/s, and maximum read speeds 2000 Mbps. 665P has IOPS 250000 on reading and 250000 on writing operations per second.

Endurance and warranty

Manufacturer provide 5 years of warranty that limited by 300 TBW.

665P (1Tb) produced by Intel may work on PCIe Gen3 that is undoubtedly slower than PCIe 4. The sequential write speed is 2000 Mb/s, that is common for this expansion standard. The drive can write 300 TBW, that is poor in comparison with competitors. On balance, Intel 665P 1Tb is a well-rounded NVMe SSD.

+ Pros

  • Good writing speed
  • Capacity

- Cons

  • PCIe 3.0
  • Writing speed

Intel 665P NVMe SSD vs Intel 660P NVMe SSD


The Intel 665P has DDR3L. Dynamic Random-Access Memory in their controller help to improve I/O performance and endurance.

The 665P 1Tb due to the low density of memory chips can last without additional heat sinks. Some motherboards or laptops already has thermal pads above or below the SSD for better performance during times of heavy loads.

The Intel 665P 1Tb has sequential write speed 2000 Mb per second, sequential read speed 2000 Mbps. Storage works on Silicon Motion SM2263EN controller and M.2 3.0 x 4 high-speed serial computer expansion bus standard. The NAND memory type is Intel 96L 3D QLC.
