RELIABILITY BASED FLASH PAGE SIZING

Abstract:

A storage system includes solid-state storage devices and a storage controller operatively coupled to the solid-state storage devices, the storage controller including a processing device, to receive data to be programmed to a solid-state storage device of the plurality of solid-state storage devices. The processing device is further to determine a mode for programming a flash page storing the data at the solid-state storage device based on a required reliability for the data and an anticipated number of program/erase cycles associated with the data and transmit the data and the mode for programming the flash page storing the data to the solid-state storage device, wherein the mode causes the solid-state storage device to program the data to a first portion of the flash page and program parity data to a remaining portion of the flash page.
