bash就能搞定
#!/bin/bash

size=1024

usage() {
echo "$0: Create RAM Disk with given size(default is 1024MB)"
echo " e.g.: $0 512"
exit 1
}

if [[ $# -eq 1 ]]; then

size=$1

re='^[0-9]*$'
[[ ! $size =~ $re ]] && usage $0
else
usage $0
fi

sector=`echo "$size * 4 * 512" | bc`

echo "Create ${size}MB RAM Disk"
diskutil erasevolume HFS+ 'RAMDisk' `hdiutil attach -nomount ram://$sector`

可以试试iRamDisk，目前在用感觉不错。
