Intel Releases 665p SSD with QLC NAND and increased lifespan

Yeah, that's a contradiction in the title right there as you would not expect longer lifespan with QLC based NAND. Intel launches its 665p, the successor of the SSD 660p which uses a new generation of QLC nand based on more layers.A 1TB model will be introduced, a 2TB will follow and 512 GB is even released.

Intel will be making use of 96-layer 3d QLC nand, 64-layer was used in the previous generation. Intel rates the lifespan to be increased from 200 TBW to 300 TBW. The same Silicon Motion SM2263 nvme controller is being used combined with a small dram cache and slc cache. The 1 TB model offers up to 2000 MB/s sequential reads and 1925 MB/s sequential writes, up to 160,000 IOPS random reads, and up to 200,000 IOPS random writes.

Prices are TBA, but expected to hover at a 125 USD range for the 1 TB version.

2 TB 660p is cheaper than 1 TB 970 EVO+.
760p was also nearly 1,5 times cheaper just 2 months ago. But recently Intel bumped 760p prices 1.5 times up to 970 EVO+ level.

So it is almost as fast as the old 600p now for a lot less money and almost the same durability. I know some don't like the idea of QLC but this is a nice product for the price. Any time you are getting faster than SATA6 speeds at almost $100/TB that is good.

No you don't.
You can fill an entire TLC SATA drive at 500+ MB/s with no drops in speed.

Crappy QLC goes down to under 100MB/s when the buffer fills up, and that happens quite fast !

These are drives for people that don't do anything useful with their PCs... just watch youtube, spin the mouse-wheel on facebook and talk with their grandma on skype.
