Only 12 Gb/s Serial Attached SCSI (SAS-3) drives meet every stated need. SAS-3 provides a per-lane throughput of 12 Gb/s and is full-duplex. Enterprise SAS drives include two independent ports, allowing each disk to be cabled to separate host bus adapters so the operating system can establish redundant, multipath access.
Serial ATA III is limited to 6 Gb/s, is half-duplex, and exposes only a single port per drive, so it cannot provide simultaneous redundant paths. USB 3.2 Gen 2 offers 10 Gb/s signaling but is designed for removable devices, is single-ported, and lacks the dual-path capability expected in enterprise backplanes. SDXC UHS-II media peaks around 312 MB/s (≈2.5 Gb/s), far below the required bandwidth and with no dual-port feature. Therefore, 12 Gb/s SAS-3 is the correct choice, while the other interfaces fail on speed, redundancy, or both.
