According to every drive manufacturer, it’s perfectly acceptable to mount a hard disk drive in any orientation as long as it’s not tilted and has sufficient cooling. Each drive manufacturer says on the subject of drive mounting: Seagate: “All Seagate and Maxtor-brand hard drives can be fitted sideways or upside down.

Its a solution to prevent one of the SPOFs (Single Point of Failure) i.e. DISK failure. By configuring RAID you are just providing an emergency substitute for the Primary disk. It NEVER means that you have configured DATA backup. LVM 1.     LVM is a way in which you partition the hard di...
