If you have one machine with lot of memory, and your database is not too big , you can try this. I don't know if with innodb storage can get some benefit. ATM i'm using MyISAM and i get a ultra fucking power hyper speed on mysql
The ramdrive can be stored all 5 minutes to hdd (auto).
I am using an 2gb ramdrive at home for my workbench

Experienced in the following languages/apis/ides: Java using Eclipse/AWT/Swing/NIO/JNI/Jogl, C/C++11/c++14 using QT/MFC/BOOST/STL/VS2012/VS2013/OpenGL/DirectX, Delphi using Borland, .NET/C# using VS2012/VS2013
Wait for the intel's Z68 chipset and buy a pair of 30GB SSD and a high rpm HDD drive. Use the SSD for OS and HDD caching and you will notice slight performance increase. And even in the case of power outage you won't lose the already saved data. Saving data in RAM is bad idea in server application in any case. Those ram sticks tend to break a lot. That's why you get 2gb+ for less than 100$
That is the problem and a trade off myisam is giving. With all the computing speed it offers, it has to give something up in order to compensate. Unfortunately, it is stability and security that was targeted. Losing these two, can mean the world to a system, which is why implementation is real life systems has been scarce.
