Hi all, I have been on a (mostly) successful adventure to fix the abysmally slow parity raid speeds in the windows storage spaces tool by following this incredible guide. https://storagespaceswarstories.com/storage-spaces-and-slow-parity-performance/#more-63
I have 6 identical Crucial 2tb MX500 ssds over sata directly on my motherboard
These are split into 2 different 3 drive storage pools (as to my knowledge you cannot follow the guide above with 6 drives, one being parity.) Either way my pools are configured the same: 3 columns with an interleave of 32KB and a Allocation size set to 64KB. Same as the guide. Yet when Running both through CrystalDiskMark I am getting half or less read speeds on one of the arrays, and I cant for the life of me figure it out. Increasing and decreasing the allocation size and interleave does not fix the issue and reconfiguring both leads to the same result again. See screenshot attached.
Looking around online I am not seeing anything, but I am new to raid and parity calculations using storage spaces so its possible I am missing something but I am not sure what. Anyone have any ideas what would be causing this massive difference in read speeds? Any ideas would be greatly appreciated.
