What is JBOD array?
JBOD (which stands for “just a bunch of disks”) generally refers to a collection of hard disks that have not been configured to act as a redundant array of independent disks (RAID) array. Typically, a RAID array will appear to the operating system as a single disk. JBOD is an alternative to using a RAID configuration.
What is the difference between RAID 0 and JBOD?
The difference comes down to what you need: RAID 0 provides better performance by spreading data across multiple drives in the RAID for faster writing and reading. This is important for high audio track counts and video applications. JBOD creates one large “logical” drive from several smaller drives.
Can you RAID JBOD?
JBOD, which stands for Just a Bunch of Disks or Just a Bunch of Drives, is a storage architecture consisting of numerous disk drives inside of a single storage enclosure. JBOD enclosures are usually not configured to act as a RAID, but they can be.
What is JBOD Wikipedia?
JBOD (abbreviated from “Just a Bunch Of Disks”/”Just a Bunch Of Drives”) is an architecture using multiple hard drives exposed as individual devices. A spanned volume provides no redundancy, so failure of a single hard drive amounts to failure of the whole logical volume.
Is JBOD safe?
IF JBOD uses spanning, you’re running the same risk as in RAID 0: one drive dies and the entire array is lost. You can span drives(partitions) with plain 2k & XP pro, I think XP home may do it as well, so you may not need to buy a controller for that purpose.
What happens if a JBOD disk fails?
JBOD means that your data is on single, stand-alone hard drives. If a one of your JBOD disks fails, the data on that disk is probably lost. Both RAID and JBOD have their place. Each can be successfully implemented into your data storage and backup strategies.
What happens if a drive fails in JBOD?
Does JBOD have redundancy?
Redundancy and Availability While JBOD can provide redundancy for components such as power supplies and cooling fans, there is none at the disk level. What this essentially means is that if a disk in an array fails, you will lose any data that does not have a backup.
