PCDoc from the BYOB podcast has come to the conclusion that Windows 8 Storage Spaces feature is not up to par:
…the performance of the Storage Spaces is pretty bad in comparison to a hardware solution…it is simply not worth using for anything serious.
Although we must remember that Storage Spaces and Windows 8 is still in beta, it is good to know that we also have third party solutions in the form of StableBit DrivePool and Drive Bender.
