Back in the day, as in, say, the last century, RAM disks were all the rage among the Mac and Windows PC faithful. Think of a RAM disk as another way to store or copy files on your Mac.
A RAM disk uses the Mac’s RAM– random access memory– but is far, far faster than copying or moving files to and from the Mac’s SSD (solid state storage) storage or hard disk drive. If a Mac app continually pulls up a file from the SSD or HDD, it can pull and save that file faster to a RAM disk instead.
If you’re a Mac user who complains about the slow loading times of certain files you use in an app, RAMDisk Manager can make access an order of magnitude faster. Usually. This inexpensive Mac utility makes it easy to setup and use a RAM disk, and, importantly, synchronize the RAM disk with folders on your Mac.
Setting it up is easy. Super easy. Give it a name, set the size and location, and adjust the sync settings and alerts as needed.
RAMDisk Manager displays the RAM disk and the synchronized folder in a floating window. You can eve setup warnings for the RAM disk storage reaches a specific amount.
There’s not much to grumble about with RAMDisk although in my tests my Mac with 16GB RAM would start swapping files when the RAM disk hit two to four gigabytes (I run a large number of apps at the same time).
If your Mac has plenty of RAM but is still running a hard disk drive instead of a faster SSD, you’ll notice the increase in speed right away. For Mac users with SSDs and smaller files, there’s not much difference in access speeds that I can tell. The larger the file, the faster the RAM disk appears to work.
