I have a server with 8 drive bays, and I have eight 4TB drives. Would it be best to do one RAID10 with all drives, or one RAID1 with two drives and then a RAID10 with the remaining six so that the operating system (Windows Server) has its own drive (and not just a partition)?

The large disk will house 1-3 VHDXs. My priorities are first: redundancy, second: write speed, third: read speed. Backups happen on a different machine.

Thank you for your time and feedback.

This question is opinion based, but if it were me I'd create a RAID 1 array for the OS and a RAID 10 array for the virtual machines.

  • I appreciate the feedback. Can I ask how you reached this opinion? My thoughts are "If something goes wrong the second disk the first one is 'insulated' a bit." Are yours along those same lines? – Kyle Souza Mar 17 '22 at 17:37
