Hi Carlos. I'm Greg, 10 years awarded Windows MVP, here to help you.
I would not use Storage spaces or any other RAID or modified RAID as it can lose your files if one hard drive dies. There's no good reason to use it with today's huge SSD storage drives and backup imaging.
Look over these threads to make your own decision or fix your problem:

I would personally uninstall Storage Spaces to reduce the risk:
