How do you break a RAID?
Proper steps to break RAID
Filesystems->RAID->select second component -> fail.
Disk->Utilities->Eject second disk.
Shutdown the box and take second disk out. Note.
Power back up.
Filesystems->RAID->Stop array.
Insert back second disk and mount it as another fs.

Will RAID automatically rebuild?
When a hard disk drive goes defunct (DDD), a Rebuild operation is required to reconstruct the data for the device in its respective disk array. Only RAID level 1 and RAID level 5 logical drives are reconstructed. RAID level 0 logical drives containing data cannot be reconstructed and therefore will be marked blocked.
How often do RAID drives fail?
RAID 0 failure is a real possibility. Consider this: the annual failure rate of drives is 2.5%. So with every drive you add, you increase your risk of malfunction. You get the benefit of higher read/write speeds, but the more drives in your configuration, the greater the chance of disk failure and data loss.
Your goal is to kill just the one or two bugs you just sprayed. You didn’t aim correctly and sprayed in an area you didn’t mean to treat, or you sprayed more than you intended to. You accidentally spilled the product. The spray is in an area where someone might slip on it.

Prepare the array. Determine and secure the current state of an array; label the drives, wires, cables, ports, controller configuration, etc.
About this task. When a single disk in a RAID 5 disk array fails, the disk array status changes to Degraded. The disk array remains functional because the data on the failed disk can be rebuilt using parity and data on the remaining disks.

Which RAID is best for data recovery?
A RAID 10 optimizes the disks then makes an individual copy of each disk. This process leaves you with five groups of two disks. By giving you more copies of the information, a RAID 10 provides better recovery because you can have multiple disks fail without losing all your information.
Is mirroring better than RAID?
Mirroring provides the best performance after a failure because data can be used directly from the mirrored disk. Device parity protection is be used directly from the mirrored disk.
Can RAID be as fast as an SSD?
Sadly, when it comes to raw speed, a single SSD is always going to win out against a RAID 0 hard drive setup. Even the fastest, most expensive 10,000 RPM SATA III consumer hard drive only tops out at 200MB/s. In theory. So two of them in RAID0 would only manage a little under twice that.
