Storage Space are a great future in Windows 10 where you can make multiple harddrives be as one in the system. This can be useful on your DAW. You can just ad a drive to the system without any hastle and your storrage space is as bigger as that new drive.

 It sounds like a process to make something difficult that wasn't difficult before. I have 3 storage drives and I don't see the benefit.  It's like RAID in a way. 

Interesting.... what are the benefits / negatives (risks!)

 To make you think W10 is better than W7 or 8.

the immediate one that springs to mind is not remapping where you store files/data if you run out of space on your existing drive...

I think it's a great idea and one that had to happen sooner or later. 
 
Let's say your main sample drive gets full so you buy another drive. Instead of having to remember whether a library is on "Samples 1" or "Samples 2," everything's stored in the same logical drive. It just adds another layer of organizational flexibility. 

This is much easier than ride, as shake stated, you can add HDD and SSD with just minor editing. And since SSD is not sheep it makes sense for those who wants to write audio and read samples from SSD. You can buy a 256 GB without stressing if its going to be to small in 1 year. Then you just ad a drive and enable it to the system. 512 GB!!!
 
There is advantages of using SSD in home recording. They are quiet and don't get hot.

I wonder how this compensates for keeping at least 10% of space free on SSDs. I've always been wary of using RAID in the studio because I have my setup in a way that uses different drives for different things to keep from bogging down the system and backing up where things need to be backed up. It would be nice to have a single SSD volume though for my larger libraries so long as it doesn't impact the performance.
 
Anyone tried this yet and can drives be added that already have data loaded on them?

The main advantage for storage spaces is in enterprise type of storage. You have the ability to span multiple devices, to have it provide various levels of redundancy for various kinds of files, etc. For a home system, I'm not sure it is of a whole lot of use, but hey nice of them to provide it.
