Filed under CentOS, Fedora, howto, Linux, Software, System, Tips, Ubuntu by on January 28, 2011 at 11:44 am {no comments}

RAMDISK is part of system memory which user can use as a normal disk space. The advantage of RAMDISK is faster read and write access in comparison of Hard Disk.

By default Ubuntu mount RAMDISK on /dev/shm/ directory.

To setup RAMDISK on other distributions like Fedora or CentOS, you can follow below method. My machine’s actual RAM size is 2GB out of which I am going to use 512MB for ramdisk.

NOTE : You can also use below method on Ubuntu

mkdir -p /media/ramdisk
mount -t tmpfs -o size=512M tmpfs /media/ramdisk/
