Purpose: Compare Seagate Exos X16, X18, X20, X22, X24 and Exos M models, interfaces, sector formats, prices and NAS suitability.
Direct answer: For a normal SATA NAS or home server, begin with an exact SATA model and confirm that the enclosure supports its capacity and 512e sector format. Use SAS only with a compatible HBA or backplane. Exos X24 is the established 12TB-to-24TB channel generation, while Exos M carries the newer 24TB-to-32TB HAMR-CMR models.
