Why is RAID 0 not an option for data protection and high availability?

RAID 0 is data striping. This means that data will appear to a user as one logical disk but all the data is distributed among two physical disks. If one disk fails operation cannot continue and data is lost.
RAID 1 uses two disks that are mirrored copies of each other. If one disk fails, operation can continue and no data is lost.

How do you install hardware raid 0 in a computer?
Hardware RAID 0 is basically a controller card that controls the RAID functions such as a SCSI RAID config. Some motherboards come with RAID functionality built in the motherboard. If you have a RAID adapter in your computer and want a RAID 0 configuration with no data protection. You must download software from the RAID adapter manufacture, usually a bootable CD and run the configuration program at boot up using the CD. Keep in mind that this procedure will destroy any data on the drives. Listed below is a list of abbreviated possible configuration types. Raid 0 - No data protection Raid 1 - One drive mirrored to another Raid 5 - Multiple drives combined together with data protection. Make sure you backup your data first...

What is the definition of Raid Data Recovery?
RAID is a system of data recovery that provides protection from data loss by copying and spreading data across multiple drives so that if one fails, it can be reconstructed based on information from the others.
What technology would be best to use for drive redundancy and data protection?
A Raid technology.
What is RAID 10 for computers?
To understand what is raid level 10 you need to know what is Raid 0 and what is Raid 1. Raid 0 is writing of certain data to two hard drive in stripes, thus doubling the speed of writing or loading data. Raid 1 is parallel writing of data to two hard driver. Whatever is written to drive one is written to drive two, thus having automatic backup of data in case of something goes wrong. Now if you combine these two, you get Raid 10. Your data are first written in stripes to hard drive let's call them 1 and 2 and then data from 1 and 2 are copied to hard drive 3 and 4 respectively. All this happen on the fly. This give speed and security of your data if one of primary hard drives fails.
Why would you need two hard drives?
To increase the physical storage capacity of the computer, or to create redundancy in RAID configurations for data protection.
How can you recover your data after a raid?
There is software available, such as Runtime that can recover any information you have lost to a Raid. There are also companies such as RAID, and Data Tech Labs that can provide help in a situation where data has been lost to a raid.
Which RAID version does not provide data redundancy?
RAID 0.
What are the advantages of data recovery?
Our experience of recovering the data from failed Raid Systems is unparalleled. We recover data from failed RAID 0, RAID 1, and RAID 5 systems regardless of configuration or manufacturer. We also recover data that has been rendered inaccessible as the result of a rebuild failure.
What is the use for raid 0 data recovery?
Raid 0 dad recovery is for emergency use on computer services. When data is corrupted or damaged, Raid 0 Data recovery can help by offering speedy recovery of data or files.
Which RAID level mirrors one hard drive with a second drive so that the same data is written to both drives?
That is RAID 1. It uses two drives with identical data so if one fails, you have the other drive. One variation of RAID 1 used by certain controllers is to write as RAID 1 but read more like RAID 0 (but without the striping). That way, you have the write protection of a mirrored set, but can use the two drives to do interleaved reads for a read performance boost.
What exactly does the term raid data recovery refer to?
"RAID" is short for "Redundant Array of Inexpensive Disks." RAID are groups of storage systems. RAID Recovery is the act of recovering data from those storage systems.
