After the RAM is allotted, it calls on the "diskutil" command to format the allotted RAM and name it "ramdisk," which will cause the Finder to mount it under that name in the default mount point /Volumes/. First it invokes "hdiutil" to attach an allotment of RAM but not yet mount it since there is no filesystem on it yet. When run in the Terminal, this command does a number of things (note the single quotes are actually "grave accent" marks). You can also run a similar script in one line using Apple's "diskutil" and "hdiutil" commands, which result in a more user-friendly RAM disk than the previous script.ĭiskutil erasevolume HFS+ "ramdisk" `hdiutil attach -nomount ram://128000` sh filename suffix, right-click it and choose TextEdit under the "Open With." menu. The number represents sectors, and there are 512 bytes per sector of RAM. The default value for "NUMSECTORS" in the script will give you a 64MB RAM disk, but you can increase this number if you would like.
This will enable execution of the script by the owner of the file (you).Īfter this is done, to run the script just open a Terminal window, drag the script to it, and press enter. Then open the Terminal and type "chmod u+x " followed by a single space, drag the script file to the Terminal window, and press enter. The process basically involves creating a mount point for the disk, using the hdid command to allocate the RAM for the disk, and then create a file system on the disk so it can be used and mount it to the mount point.Ĭopy this text to a plain text document (not rich text) in TextEdit, and save it with ".sh" as the filename suffix (i.e., "ramdisk.sh").
RAMDISKCREATOR MAC HOW TO
In OS X Apple has done away with RAM disk management and creation in favor of tools like disk images and networked drives however, RAM disks can still be created if you want to use one.īuried in the manual pages for Apple's command-line disk-image-management utility "hdid" are a few instructions on how to use this command to create and mount a RAM disk. The RAM disk was kept active even when the computer was off, so in some cases if you had enough RAM you could even copy the system folder to it and load the Mac from a cold boot in a few seconds. Being stored in RAM, the drive's contents would load nearly instantaneously and could therefore be used to quickly launch applications and load documents that were frequently accessed.

Furthermore I will happily provide the source code on request.
RAMDISKCREATOR MAC DOWNLOAD
If you are still on Lion or Snow Leopard please download RAMDiskCreator 1.2. You can download RAMDiskCreator 1.4 for Mountain Lion or better here. In the background the same command is used as described above. Only the size and the volume name have to be provided.
It’s a freely available tool and offers a graphical user interface for the RAM disk creation. To simplify the process I created RAMDiskCreator. For example to calculate the size parameter for a volume with 4GiB the following formular is used:īe aware that the content of a RAM disk is permanently deleted as soon as it is ejected! Only use it as temporary storage! RAMDiskCreator That means the size in bytes has to be divided by 512. The size of the disk is based on the page size number of 512 bytes sectors.
RAMDISKCREATOR MAC MAC OS X
Mac OS X includes a way to create RAM disks using the following Terminal command:ĭiskutil erasevolume HFS+ 'My 4GB RAM Disk' `hdiutil attach -nomount ram://8388608` If you STILL use earlier versions take a look at the article posted by OSXDaily. This article covers Mac OS X 10.5 and later. This can be used to do disk intensive operations in a fraction of the normally required time. They offer a filesystem in RAM and therefore outperform most of all other storage systems.
