What the status labels mean

Confirmed: Recorded research passes agree within this variant; this is not independent human review or hardware validation.
Single source: Only one underlying document, or one pass, supports this assignment.
Device-specific: Supported for the named equipment or wiring only. Check your device’s manual.
Unverified: Missing or conflicting evidence. Do not wire from this row.
Not connected: The source explicitly says NC, no contact or no pin for this wiring.

P199 Micro SATA — **Partial**: named drive versus standard host/device — A's Intel X18-M agrees on the common signal and rail positions but explicitly does not connect P5/P6 (optional 5 V); B's standard defines those rail contacts. A assigns P7 DAS and P8/P9 optional manufacturing use; B retains standard device P7 reserved and P8/P9 vendor-specific/unverified, versus host ground/NC uses. Keep all three variants rather than imposing standard optional functions on that drive. Intel-authored manual is hosted by Kingston; B uses SATA-IO directly.
X18-M P5/P6 are not connected and P7 is DAS. Other models/later optional P8/P9 functions are unverified.
