Intel's Memory and Storage Day event today in South Korea was mostly focused on enterprise and datacenter products, but they did announce an upcoming consumer SSD: The Intel SSD 665p. This is the successor to the Intel 660p, the first and most successful consumer SSD to use four bit per cell (QLC) NAND flash memory. The 665p isn't a major update: it keeps the same Silicon Motion SM2263 4-channel controller but updates the NAND to Intel's second-generation 96-layer 3D QLC NAND. This newer QLC keeps the same 1024Gb per-die capacity while shrinking overall die size, so we don't expect any change to the range of drive capacities offered nor any major performance changes—but it may lower prices a bit.

Intel showed off the 665p with a live demo pitting the 1TB 660p against a 1TB 665p prototype with pre-production firmware, each installed in otherwise identical ASUS notebooks. Intel used a beta version of CrystalDiskMark 7 to illustrate the 665p's performance: 40-50% improvement to sequential transfer speeds and about 30% faster random access speeds.
