Flash memory has moved from being used for short-term, low-volume storage and data transfer, to becoming the primary alternative to magnetic disks for long-term, high-volume and persistent storage. The authors present desiderata for improved I/O performance of spatial data structures over flash memory and hybrid flash-magnetic storage configurations. They target the organization of the data structures and the management of the in-memory buffer pool when dealing with spatial data. Their proposals are based on the fundamentals of flash memory, thereby increasing the likelihood of being immune to future trends.
