Use Case
1.92 TB is the entry capacity in the CD8-R family and the usual choice for boot-and-log volumes in a tiered node, with the bulk capacity carried by 7.68 or 15.36 TB drives behind it. It draws 13 W active and runs to a 75 °C composite temperature, so it tolerates the warm rear bays of a fully populated chassis.
