I would forget about that very quickly ...
For starters, I thought it was quite complex and confusing to setup.
There are quite a bit of problems with Storage Spaces too - a quick google will reveal a whole new hell to you. Dissapearing pools, disapearing disks, disks going offline for no appearent reason, sync issues.
Disks are not compatible with any other system so you're basically limited to your own system - I don't know what would happen if you unplug all your disks, run to your neighbor (with Windows
and hook them up but I fear its not going to be that easy.
When I dabbled with Storage Spaces I unplugged the power to a disk. The disk went offline - obviously - but it took a few minutes for it to show in Windows Management tool. I was sitting there refreshing the window, closed it, opened it, it wouldn't show the disk offline! I had event viewer open and almost immediately I got a warning or error (dont remember exactly) but in the management tool for storage spaces it took a minute or two. Same when I plugged another disk in - it took a while to pick that up too. IIRC it wasn't very straightforward to replace the failed disk with the new one.
Besides these quirks its actually quite slow too.
Maybe someone else has a more positive view but personally I wouldn't trade something proven reliable (drive bender) for this relatively complex system.
