Linux RAM drive support/performance

["Paul McHale" <pmchale@doubleesolutions.com>]

Does Linux support any RAM drive(s)?  How much faster are these drives over
an attached drive?  Is there a CPU performance penalty?

We would like to replace our mechanical drive with a small (<4GB) RAM drive.
The mechanical drive is getting pounded 24 hours a day.  In addition to
fatigue, the extra performance would be nice.

Is it true the x86 architecture is limited to 32 bit addressing and will
never support more than 4GB of address space?  Trying to see what the
limitation will be.

I know this is a lot of questions.  As always, any help is appreciated.

Regards,

Paul
