Storage Capacity of "New Black Xbox 360": Clarification

No "new black Xbox 360" was released — the console was discontinued in 2016. Original models came in:

• 4 GB: Entry-level, online-focused.
• 120 GB: Mid-tier, common.
• 250 GB: Maximum internal capacity.

Note: Usable space is less due to OS reserved space. "Slim" models (2010+) were black but not "new" post-2016.
