Intel has released the successor to its first-gen QLC SSD, the 660p. The 665p model has been upgraded from 64-layer 3D QLC NAND to 96-layer 3D QLC NAND, boosting performance by up to 13.6% and endurance by an impressive 50%. One and 2 TB models are available.

Both capacities of the 665p have 50% higher rated write endurance than the 660p, bringing them up to about 0.16 drive writes per day (DWPD) from the 660p’s 0.11 DWPD. This is still a lot lower than the 0.3 DWPD that is typical for low-end consumer SSDs that use TLC NAND, but the increase does show that Intel’s feeling more confident in their second generation of QLC.
