TmpDisk

TmpDisk allows you to create a temporary disk based on your machine’s RAM memory. This has the advantage of supporting fast access to the data stored on it, which makes it ideal to avoid the delay caused by saving large files while they are being edited or you are extracting the contents of archives.

Moreover, since everything is erased when the system is restarted or the volume is ejected, the application can be used to protect your privacy by wiping traces of your activities. Although the tool could not be any easier to use, it is a shame its help documentation is extremely limited.

The application runs unobtrusively on the Menu Bar. By clicking on its icon there, you can access its menu. Not many operations can be done with this tool except creating a new temporary disk. In this regard, it would be necessary to supply a name and the intended size, which, unfortunately, cannot exceed 1.5 Gb. Moreover, there are options that allow setting the tool to create the new disk automatically with every startup. Likewise, it is possible to hide the volume.

In general, TmpDisk can help you save some time by reducing the time it takes to manipulate large amounts of data. The product is opensource so there is nothing to lose if you give it a try.
