Patriot's new FUSION series SSD with 64MB of DRAM cache is the next in their lineup. As with other new models of solid-state disk drives arriving for Summer 2009 --upping the amount of the onboard DRAM cache buffer is giving SSD manufacturers an easy way to increase overall write performance and data transfer rates.

Much as with traditional spinning platter drives - and the use of cache in general when it comes to computers - cache behaves rather predictably: A little cache helps ALOT, a bit more helps a bit more incrementally -- but at some point the performance curve tends to flatten out very quickly.
