Phrase: RS-449 | Statement: [EIA-449, alsoKnownAs, RS-449]

Target entity: RS-449
Context triple: [EIA-449, alsoKnownAs, RS-449]

• A. SFF-8639
  SFF-8639 is a high-speed connector and interface standard used primarily for U.2 NVMe solid-state drives in enterprise storage systems.
• B. SFF-8482
  SFF-8482 is a standardized internal connector interface designed specifically for Serial Attached SCSI (SAS) drives, allowing compatibility with both SAS and SATA devices in enterprise storage systems.
• C. SFF-8484
