A SAS drive requires a compatible SAS controller or backplane. A normal motherboard SATA port cannot operate a SAS drive.
Check sector-format support in the controller and operating system, particularly for native 4K (4Kn) variants.
Compare new and renewed offers separately. The manufacturer specification does not guarantee the warranty or return policy of a marketplace seller.
