Yesterday, Teradata announced Teradata Intelligent Memory – part of the Teradata Unified Data Architecture. I previously wrote that Teradata found the following when studying data usage:

1. 43% of I/O uses 1% of cyclinders

2. 85% of I/O uses 10% of cyclinders

3. 94% of I/O uses 20% of cyclinders

Teradata has now extended their analysis and their technology to determine what data should be in-memory and so they are optimizing the memory of modern database systems. Therefore, unlike others who want to put everything in-memory, Teradata is using smart algorithms to determine what should be in-memory and hence doing the price/performance trade-off with a kick – significantly lower price because not everything has to be in-memory but almost similar performance. This is big news because as data volumes grow, cost becomes an issue and Teradata is able to keep costs down while maximizing performance.  You can read more about it here: Teradata Intelligent Memory.
