NAND Types
The NAND is the Xbox 360's internal flash storage. It holds the system software, bootloaders, and per-console configuration. Understanding your NAND matters because backing it up is the foundation of a safe project, and its type affects how you read and write it.
Why NAND matters
- It contains your console's unique configuration, which cannot be recreated if lost.
- A verified backup is your primary recovery path if something goes wrong.
- The method you choose involves reading and, in most cases, writing this storage.
Sizes and styles
Across the console's life, NAND capacity and arrangement changed. Some boards use a small internal flash chip; later boards, particularly certain Corona slims, use a different storage style. The size and type influence the tools and procedure you follow.
| Aspect | Why it matters |
|---|---|
| Capacity | Determines backup size and tooling expectations |
| Storage style | Affects how the chip is read and written |
| Board revision | Corona variants notably differ in NAND style |
Always back up first
Before any permanent change, create and verify at least one good NAND backup. This single step prevents the worst outcomes.
Confirm your board revision so you know which NAND type you are dealing with.
