Performance - FlashFX v6.10 vs v5.11

With the introduction of FlashFX v6.10, Datalight incorporated significant changes to the allocation strategies used by FlashFX. Several of these changes were a result from the more stringent requirements of flash technologies becoming available. For example, past NAND flash parts could tolerate multiple programming operations within a single page of flash memory; newer flash parts cannot.

This paper provides an overview of the changes in the performance of FlashFX and NAND flash memory between FlashFX 6.11 and previous versions of FlashFX, specifically version 5.11. The basic algorithms and data structures used prior to version 6.10 had not been changed dramatically since 1997.
