Slow Performance in Storage Spaces

It seems more people are experiencing slow performance when using The new feature Storage Spaces which is in Windows 8, Windows Server 2012 and WS2012e.

Storage Spaces - Physical Drives

One user by the name of David Trounce in a thread on the TechNet forums is stating that the performance issue is being caused by controller configuration and is suggesting using disks in pools in multiples of 8 and making sure these disks are as similar in size as possible.

Another article looks at possible design flaws in Storage Spaces, stating:

“A Storage Space operates at the block level while it should work at the file level instead. The benefit of potentially high read speeds (chunks from larger files are stored on different drives and can be read concurrently) is not relevant in SOHO scenarios. But the increased probability of error is.”

More on that article can be found here.

Storage Spaces may not be fast but at least it is as good if not better than our old friend Drive Extender.

    I have been pretty happy with StableBit DrivePool, I think even if I end up upgrading to 2012 I will continue using it rather than Storage Spaces. It does everything I need it to do in a logical manner and it seems to be as fast as using a single drive for everything I have used it for.

    One thing that DE does that Storage Spaces apparently doesn’t is automatic rebalancing of storage across the drive pool.

      To all googlers who spend hours searching the net for a solution to the rebalance problem in a parity configuration (Like me ;). At the moment (January 2013) there is no Microsoft tool that does the job (includes PowerShell commands). To ensure that all hard drives can get the same level, you have to copy all the data once, and then delete the originals. That takes a while, but is currently the only way.
