Free RAM as cache

[rutra80]

Would it be possible to use free RAM as cache instead of a fixed amount of RAM that is taken away from the OS? That's how Windows buffering works.

So far this feature is not available. But thank you for the suggestion, we're also thinking about this function.

Also, it would be great if size of SSD cache didn't use up so much RAM. Intel SRT has an addressing scheme which avoids that problem I think, VeloSSD too. Would there be any drawbacks?

Do you mean the overhead memory for SSD cache, or the overhead storage? I think you may use a bigger cache block size to reduce the overhead.

I meant overhead memory for SSD cache. I know that increasing block size reduces the overhead, but there seem to be ways to eliminate the overhead almost completely (as in mentioned software).
