I am often asked about the value of flash memory in OLTP database applications. This blog post discusses flash technology in this context. First, I discuss the future of flash in general; then I turn to flash (and other future storage technologies) in the context of a main memory DBMS, such as VoltDB.

Flash memory is clearly a “moving window”, since its price and performance are changing quickly. Historically, flash could only be written a few thousand times, before it would “wear out” and have to be replaced.
