ramBunctious 2.0 is a RAM disk program for OS X. As far as we know, this is the first RAM disk software for Mac OS X. We tried it out and it worked as advertised. However, it appeared to be quite similar to what you get if you create a writable disk image with Disk Copy. So we asked the author, Bob Clark, about what the differences were. He replied:
"If RAM is tight on your machine, then OS X's caching and virtual memory will make a disk image perform similarly to a RAM disk. If there is some "elbow room" of RAM, then a RAM disk's performance will be substantially better than a Disk Copy image."
This article offers more details, adding: "ramBunctious RAM disks offer substantial performance gains over hard drive access. But it would be myopic of us to recommend using RAM disks only for performance reasons. RAM disks require less power and allow the hard drive to spin down sooner and spin up less frequently."
