Pure Storage FlashArray//C with QLC

Pete Kirkpatrick, VP Engineering, Chief Hardware Architect, gives a deep dive into the Pure Storage FlashArray//C with all-QLC flash. Pure Storage announced an all-QLC version of the FlashArray//C previously, but this array is now shipping, bringing a new price point for the all-flash storage array market with availability, reliability, and enormous capacity. Kirkpatrick gives some background into the use of QLC NAND flash, including the problems that arise with lower performance and endurance of this medium. In a discussion with the Storage Field Day delegates, he presents the unique technical capabilities Pure Storage brings to this type of flash.

so, this appears to be a copy-ish of the Vast Data array design using a large optane cache and QLC.
