SSD Spare Inventory
Spare SSD Module Inventory + Replacement Process
Spare SSD module inventory + L1-MNT replacement process maintaining digital storage capacity over mission lifetime.
Purpose
Spare SSD module inventory + L1-MNT replacement process maintaining digital storage capacity over mission lifetime.
Context
Child of L2-DVT-DIGI within the Lunar Ark system
Principles
- ▸Standardized SSD module form factor
- ▸Inventory ~50% of installed base
- ▸Robotic replacement via L1-MNT
- ▸Wear-out prediction triggers replacement
- ▸Sourced via Earth import (rad-hard NAND unavailable from ISRU)
Typical implementations
- ▸ISS ORU spare-parts heritage
- ▸Aerospace storage redundancy
- ▸Data center spare-drive standards
Lunar considerations
- ▸Earth-imported in bulk shelf-stable
- ▸Long-shelf-life monitoring
- ▸Replacement scheduled per L3-MNT-PRED prediction
