Intel 660p 2TB NVMe SSD

The Intel 660p Series 2TB M.2 2280 drive uses PCIe NVMe 3.0 x4 and Intel QLC 3D NAND to deliver up to 1800 MBps sequential read and write. It is built for consumer notebooks, desktops and mobile devices that need high capacity in a thin 80mm form factor.

PCIe NVMe 3.0 x4 practical limits

The NVMe 3.0 x4 interface removes the throughput ceiling of SATA while fitting the standard M.2 2280 slot. Sequential speeds reach 1800 MBps and random performance reaches 220000 IOPS, with active power draw of 100 mW and idle draw of 40 mW. Operating temperature spans 0°C to 70°C.

Upgrading from SATA to this drive

Replacing a SATA SSD with the 660p adds NVMe bandwidth and up to 2TB in the same footprint, backed by 400TB written endurance and 1600000 hours MTBF. The jump is worth it when everyday computing needs more capacity and faster transfers without changing the M.2 slot.

Questions about this item

Should I pick the 2TB 660p or a smaller capacity for my laptop?

The 2TB model uses QLC 3D NAND to fit twice the data in the same M.2 2280 footprint, so you get maximum storage without a larger drive.

What does the 1800 MBps sequential speed mean for everyday use?

It lets the drive read and write large files such as videos or game assets at up to 1800 MBps, cutting load times compared with SATA drives.

Does the PCIe 3.0 x4 interface limit the 660p in a modern motherboard?

The drive runs at PCIe 3.0 x4, so its 1800 MBps ceiling is set by that link; a faster slot will not raise the drive's own maximum.
