Final Thoughts

Intel chose to only offer the 665P in one and two terabyte capacities. This is the first time we've seen a series of SSDs by Intel or any other SSD retailer, with a minimum of 1TB capacity. We recognize that as a testament to what the future portends for solid state storage. QLC flash is taking over, TLC flash is on the way out.

While not what some would initially prefer, QLC flash is the most advanced flash ever made. In real-world consumer scenarios, QLC can perform just as good as any type of flash. Read functions are typically just as fast coming off QLC flash as they are coming off MLC or even SLC SSDs. And to top it off, QLC is inherently more cost-effective due to increased density.

Intel was the industry's first to offer consumer SSDs with 4-bit (QLC) flash. This ushered in a new class of value-oriented NVMe SSDs that perform exceptionally well relative to the cost. Intel's 660P was the first, and even though it was maligned in the beginning, it turned out to be one of the best and most popular SSDs ever made.


We believe that user experience is what matters most. As clearly demonstrated by the above chart, Intel's 665P can deliver a user experience that is a cut above. Only now with an advanced benchmark like PCMark 10's storage benchmark, can we see by the numbers what kind of user experience Intel's QLC SSDs deliver. And it is exceptional.

Looking back at our testing, we find several places where Intel's 665P shines. First, we love the 4K QD1 read performance we got from CDM and Anvil's. The next thing we noticed as outstanding was the drive's performance when writing our 100GB transfer block. After that we came away thoroughly impressed by the drive's game level loading speed of under 11 seconds. Finally, and most impressive is where the 665P lands on our TweakTown User Experience chart. This shows that Intel's 665P is definitively one of the best consumer SSDs on the market, regardless of price.

QLC, as offered up by Intel, is something we can really get behind, which is why the 665P 1TB has earned TweakTown's highest award.
