Server Fault is a question and answer site for professional system and network administrators. It's 100% free, no registration required.

I'm building a cheap server from commodity hardware that should have at least some fault tolerance regarding its storage. Now that "Storage Spaces" are available directly in the Windows server OS, is there any point in trying to set up a RAID array (probably RAID 1 in my case)? Or, to make the question more exact, what are the advantages / disadvantages of Storage Spaces vs. RAID 1?

It's same - resiliency, time of recovery (RAID-1 doesnt recover), performance etc, on single raid you got the same. –  Andrew Smith Jun 29 '12 at 21:54

It's just software RAID at the OS level.

So the actual question here is what are the advantages and disadvantages of software RAID vs hardware RAID? (And you can find answers to that just about anywhere.)

Honestly, I'd avoid it for a while, at least outside of test scenarios. Let someone else be the guinea pig, and if/when it becomes a stable, resilient technology, then consider implementing it.

I shudder to think about what new and interesting bugs will be discovered when Windows rot or a malware infestation or a really bad misconfiguration force you reinstall your OS. Or it's time to upgrade your aging Windows 2012 Server install to Windows 11, Enterprise. I sure wouldn't want to find out with my employer's data... or my data.

Would you?

My setup would be a couple of physical disks to host this Storage Space and Windows on it, Hyper-V installed and the real work being done inside those VMs. My hope is that Storage Spaces will provide some fault tolerance but of course I would still do full image backups regularly to another set of drives somewhere. I don't see Storage Spaces as a threat, quite to the contrary. –  Borek Jun 29 '12 at 22:05
    
Your call, but there's a reason experienced sysadmins aren't eager to dive head first into every new thing, especially in production environments. –  HopelessN00b Jun 29 '12 at 22:12
