Any idea why Storage Spaces Parity stucks at very bad 30 MB/s while a normal Raid 5 over my 4x4TB drives reaches 110 MB/s????
Microsofts Parity Implementation totally sucks... if I try the same in ZFS and NAS4FREE I get stable 270 MB/s read & write on my Raid5... software only too. The CPU has nothing to do in Windows Raid 5 and stroage spaces but the speed is so crazy bad... and Storage Spaces is 3rd of the Speed of Windows Raid 5 and 10th of NAS4FREE... :-/
Hopefully we will see factor 10 increases in future...
