RAM disk in OS X is an incredibly dumb idea. The dumbest thing about it is that it creates the problem that it is supposed to solve. RAM disk is supposed to speed-up your computer by putting disk files into RAM. However, it decreases the amount of available RAM, thus forcing the OS to page-out RAM to your hard disk.Hi all,
Anyone using this? I just bought, and create ramdisk for user cache. Not sure how will it impact to the performance or SSD life.
I haven't used it, but from the description it uses your ram to build a ram disk, I'd say it may impact OSX'd performance since its allocating a lot of ram for its purposes. Additionally what happens if (when?) OSX pages out that memory to disk in part of OSX's memory management process.
All in all, I think OSX does a great job at managing the resources and the need for ramdisks have disappeared with Apple's legacy OS
Yes this is one of many commands I put in my Unix shell script, package the shell script into standard application through Apple's Automator utility and set this application as one of user's login items in System Preferences. Upon every login on my iMac, the ram disk is mounted automatically by Mac OS X without user intervention. I have also created another application in the same way to eject/umount ram disk, thus the ram disk can be created and ejected manually by user anytime (just by double clicking on respective application icon in Mac OS Finder).
