 Near Line SAS are enterprise SATA drives with a SAS interface, head, media, and rotational speed of traditional enterprise-class SATA drives with the fully capable SAS interface typical for classic SAS drives. This provides better performance and reliability over SATA. Basically, it is a hybrid between SATA and SAS.
 
 The Dell 0J4R9 is a 7.2K Nearline SAS Capacity Optimized drive. It may provide much higher capacities, but reliability and performance are not as high when compared to Mission Critical drives. NL-SAS drives use the SAS interface, providing gains of up to 30% performance over traditional enterprise-class Serial ATA (SATA). NL-SAS drives, however, use a different media size to be able to offer greater overall capacity than SAS drives but are limited to a rotational speed of 7.2K RPM. The primary benefit of NL-SAS drives is the ability to have large-capacity drives while maintaining the faster speed of the SAS interface at an affordable price point.
