RAM or Storage: Which is more important in running Storyline 3? By Mark Hahm Hello. I'm using Storyline 3 (S3) on Windows 10 with a Parallels desktop on my iMac. I've allocated 128 GB of my computer's 1TB of storage as well as 8GB of 16GB memory to Windows 10. At times, it takes a while for S3 to save files and preview documents. Which is a bigger factor in performance in this context: RAM or storage?
