Documented selection limits

Check exact SATA/SAS host and backplane, drive dimensions, sector format, firmware and security requirements. SED/FIPS variants can require a TCG-compatible controller and vary by region. No stock, lifecycle or universal compatibility promise; MTBF is a population statistic, not the lifespan of a particular drive. This exact model is SMR; validate sustained-write, RAID/NAS and rebuild workload suitability before selection.
