Intel SSD 665p with QLC flash promises 50 percent higher endurance

Intel has launched the SSD 665p, its second-generation consumer product with QLC NAND flash memory. This successor to the 660p features 96-layer instead of 64-layer QLC NAND and continues to use the Silicon Motion SM2263 NVMe SSD controller.

The biggest change is the increase in endurance, the new disk promises 200 TBW, a 50 percent increase versus the previous generation. It also promises some performance gains, as you can see in the second image below, of up to 13.6 percent.

Much more important than the performance changes is the write endurance boost the 665p brings compared to the 660p. 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.

Pricing is still unknown but AnandTech expects that after the holiday period the 665p will likely be the most affordable NVMe disk on the market. At the moment, you can get the previous-gen 660p with 1TB for $82.99 at NewEgg.
