Intel 660P 1Tb NVMe SSD detailed specifications

Intel's 1Tb 660P NVMe use Silicon Motion 2263 controller. The drive write a data location map on Dynamic-Random Access Memory Nanya 256MB DDR3 to open a files without delays. The 660P comes equipped with Intel QLC flash memory. This NVMe is offered also in 2 Tb and 512 Gb capacities.

Performance and benchmarks

This NVMe works on PCIe M.2 3.0 x 4 bus with sequential write speeds equals to 1800 Mbps, and read speeds 1800 MB/s. 660P has input/output performance 220000 on reading and 220000 on writing operations.

Endurance and warranty

Manufacturer give 5-year warranty limited by 200 Total Bytes Written. As well it has 1.6 million hours mean time between failure.

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


The Intel 660P has Nanya 256MB DDR3. Dynamic random-access memory (DRAM) in their controller help to improve endurance and input/output performance.

The Intel 660P 1Tb due to the low density of memory chips can work with no extra heat sinks. Some motherboards from the factory has additional cooling above and below the storage to improve productivity during times of heavy loads.

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