What is nearline SAS Hard Disk?

"Nearline" refers to the lower rotational speed hard disk which is usually refer to the high-capacity SATA hdd. On the other hands, "SAS is a enterprise-class drive which supposedly has a more robust mechanical specification and a controller/firmware optimized for high-volume I/O, manageability, and better error detection and correction".

So inline SAS really means  standard consumer-class SATA drives wtih SAS interface.

Large capacity with enterprise interface.....Not too bad.
