Near Line SAS: These are enterprise SATA drives with an SAS interface, head, and media, and the rotational speed of traditional enterprise-class SATA drives with the fully capable SAS interface typical for classic SAS drives. Near Line SAS drives provide better performance and reliability than SATA drives. Basically, this drive is a hybrid between SATA drives and SAS...
