Posted on November 07, 2022 by Raymond Chen

Intel's 660P internal SSD works on PCIe M.2 3.0 x 4 interface. Detailed characteristics of this SSD on this site.

Intel 660P 2Tb SSD technical specs

660P (2Tb) produced by Intel is powered by Silicon Motion 2263. This NVMe SSD has Dynamic-Random Access Memory Nanya 256MB DDR3 for mapping data, located on the NVMe SSD. The 660P comes equipped with Intel QLC memory. This drive also available in 512 Gb and 1 Tb capacities.

Performance and benchmarks

Storage works on PCIe M.2 3.0 x 4 bus with maximum read speeds 1800 MB/s, and maximum write speeds equals to 1800 Mbps. It also has IOPS 220000 on writing and 220000 on reading operations per second.

Endurance and warranty

Intel provide 5-year warranty that limited by 300 Total Bytes Written. As well it has 1.6 million hours mean time between failure.

Intel 660P 2Tb may work on PCIe Gen3 that is undoubtedly slower than PCIe 4. The maximum write speed is 1800 Mb/s, that is slower than has most of rivals. The NVMe provide possibility to write 300 TBW, that is poor compared to nearest competitors. Weighing all these factors, Intel 660P 2Tb has more disadvantages and our site highly do not advise to spend money for it.

Intel 660p NVMe SSD — Should You Buy One? — Review


The Intel 660P has Nanya 256MB DDR3. Dynamic random-access memory (DRAM) makes storage work faster, but also more expensive.

The Intel 660P due to the high density of memory chips require the installation of extra heat sink. It will reduce temperature of the controller and memory. Some motherboards or laptops already has additional cooling below or above the SSD for better productivity during high loads.

The Intel 660P 2Tb has write speed 1800 Mb/s, sequential read speed 1800 Mb per second. NVMe works on Silicon Motion 2263 controller and M.2 3.0 x 4 interface standard. The NAND memory type is Intel QLC.
