The End of Disk? SSD and In-Memory Databases

  • Guy Harrison

Abstract

Ever since the birth of the first database systems, database professionals have strived to avoid disk IO at all costs. IO to magnetic disk devices has always been many orders of magnitude slower than memory or CPU access, and the situation has only grown worse as Moore’s law accelerated the performance of CPU and memory while leaving mechanical disk performance behind.
