[ IDENTIFIED HDD // MODEL-SPECIFIC RECORD ]
Toshiba AL15SEB180N
1.8 TB 10.5K enterprise-performance SAS disk. This suffix identifies the 512n model; sector options in the AL15 family are not interchangeable.

Host compatibility and qualification
- Use a SAS-capable HBA/RAID controller and SAS backplane/expander; SATA-only controllers/backplanes cannot operate SAS drives. Validate dual-path support, power, 2.5-inch carrier and device qualification.
- Confirm 512n/native sector support, firmware and controller capacity. An older SAS host may negotiate at a lower rate only if the device and OEM configuration are qualified.
- MTTF is a population statistic, not a unit failure forecast. Verify the full part code and actual sector size; keep separate tested backups and monitor health.
