Memory Trends and HANA

If the Gartner estimates here are correct… then DRAM prices will fall 50% per year per year over the next several years… and then in 2015 non-volatile RAM (see the related articles below) will become generally available.

It has been suggested that memory prices will fall slower than data warehouses will grow (see here). That does not seem to be the case… and the combination of cheaper memory and then non-volatile memory will make in-memory databases like SAP HANA ever more compelling. In fact, as I predicted… and to their credit, Teradata is adding more memory (see here).

  1. If everyone is going to add memory to the database, how are the offerings going to be differentiated? I guess the performance will ultimately depend on the degree to which misses regarding hot and cold data can be minimized (which depends on the predictive ability of the appliance or DW), but does this development erode the value proposition of HANA?
