Intel 660P 512Gb NVMe technical specs

Intel's 512Gb 660P SSD is powered by Silicon Motion 2263. This internal SSD has Dynamic-Random Access Memory Nanya 256MB DDR3 to keep a map of where data is located on the storage. The 660P comes equipped with Intel QLC flash memory. NVMe SSD is offered also in 2 Tb and 1 Tb capacities.

Performance and benchmarks

Intel 660P use PCIe M.2 3.0 x 4 bus with write speeds equals to 1800 Mbps, and maximum read speeds 1800 MB/s. It also has input/output performance 220000 on writing and 220000 on reading operations.

Endurance and warranty

Intel provide 5 years warranty limited by endurance 100 Total Bytes Written. The 660P has 1.6 million hours MTBF.

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 660P 512Gb due to the low density of memory chips can work without further cooling systems. Some laptops or motherboards already has thermal pads above or below the storage to enhance performance during times of heavy loads.

The 660P 512Gb has maximum write speed 1800 Mb per second, read speed 1800 Mb/s. SSD works on Silicon Motion 2263 controller and M.2 3.0 x 4 interface standard. The memory type is Intel QLC.
