2 SSDs form a mirrored performance tier. 5 HDDs form a single-parity capacity tier.
The following configuration is intended for high-capacity home storage and All-in-One environments. It is the setup currently used and recommended based on the testing documented in this project.
- SSD: 2 × 120 G
- HDD: 5 × 4 T
- SSD Performance Tier: ResiliencySettingName = Mirror
- SSD Performance Tier: NumberOfDataCopies = 2
- SSD Performance Tier: Interleave = 64KB
- HDD Capacity Tier: ResiliencySettingName = Parity
- HDD Capacity Tier: PhysicalDiskRedundancy = 1
- HDD Capacity Tier: NumberOfColumns = 5
- HDD Capacity Tier: Interleave = 64KB
- Logical Volume: FileSystem = NTFS
- Logical Volume: AllocationUnitSize = 64KB
