Why are we making such a big deal about freedom of choice in the K2-H hybrid solution? Because it means you can achieve just the right mix of Flash and DRAM in a single Kaminario K2-H unit to yield the best cost/performance ratio for your applications.

DRAM yields the absolute fastest performance and lowest latency for both application random reads and writes, but it’s also the most expensive of the SSD memory types. Flash is considerably less expensive, but application writes are much slower with Flash than with DRAM because Flash has to erase data in memory first before anything new can be written to it. Your goal should therefore be to use expensive DRAM only where it is absolutely needed and leave the rest to the less expensive Flash. The K2-H lets you do just that, installing different mixes of DRAM and Flash in the same unit to achieve just the right mix for your application needs.
