I do a lot of photography, app dev, and general office tasks. My "Active Data" is projects I'm working on, photos I'm editing, etc. Once I'm done with them I'll consider them "Library Data" and move them off. I definitely get the performance increase of things I'm working on when hosted in an SSD.Thanks, this makes sense. What are you going to be mainly using this Mini for?
Sorry for the noob questions but what do you mean by active data and library data? And why the preference for active data to be on an ssd? Will your iTunes live on the other library drives?
Is this a trend with OS's and Apps and Cache needs to take more internal storage? Don't OS's take about 30GB's - do other Apps and Cache really have the chance to take up 256GB? Is there a rule of how much free space (percentage wise) that should always be on internal storage if this is where your OS is and you boot from?
As far as trends.. Everything grows. Mojave requires 18.5GB, Wheras Snow Leopard was only 5GB... Photoshop is about 1GB, Lightroom is another 1GB. As I want more apps, more space is needed..
