ReFS, 6 Disks, Raid5, Windows Storage Spaces - How do I get the performance?

Hey,

Thinking of moving to Windows and ReFS from Arch/ZFS but last time I used Windows Storage Spaces on Win10 the write performance would be fast for a few seconds then drop to 0, then fast and drop to 0. I’ve read online about columns and interleave alignment and disabling cache, but I was wondering if someone could help me out on how to set it up for fast writes preferably Raid5 on 6 Disks.

Thanks,

Jake

There is no such thing as "RAID 5" with Storage Spaces, it's just "Storage Spaces with Parity"

You will have to set up your appropriate columns and block size using Powershell. I don't have any links handy but start searching up Storage Spaces Columns Powershell.

I made several attempts and never got it working well. It's honestly best left to Enterprise setups who know wtf they're doing. That, and I'm not too bright either, so maybe that's a problem too. LOL.
- I can’t figure out the columns and allocation with refs the write is always fast then 0 then fast then 0
