There are three types of RAID
RAID 0 (Stripping without parity)
The records are distributed among all the available HDDs. The number of the HDDs may vary from one system to the other
RAID 1 (Mirroring)
This uses double number of HDDs. One stores the records while an equal number of HDDs forms the backup.
RAID 5 (Stripping with parity)
This type of raid distributes the records in n-1 disks while maintaining 1 disk as the parity disk.
assuming 4 HDDs are required
RAID 0 uses all the four
RAID 1 uses double
RAID 5 uses 4 + 1

To provide redundancy you want to implement raid by mirroring the data and use the least number of hard disks which raid level will you implement?
RAID 1
What hard disk is used for a large computer system?
RAID
What is the minimum hard disk that can be used to configure RAID 5?
Three
What is a hard-disk technology is used for large computer systems?
RAID
Which RAID level will you implement to provide redundancy?
Type your answer here...Answer Explanation: RAID 1 uses a minimum of two hard disks to mirror data for fault tolerance. Each hard disk contains a complete copy of the data. Disk duplexing improves mirroring because each disk is on a separate controller. If one disk or controller fails in a duplexing RAID 1 array, the other disk can take over immediately to provide fault tolerance.RAID 5, also known as disk stripping with parity, provides fault tolerance by striping the data across a minimum of three and a maximum of 32 disks, and by storing parity information on each disk. This allows the RAID array to recover from a single disk failure.RAID 0, also known as disk striping, is used to increase performance by striping data over a minimum of two and a maximum of 32 disks. RAID 0 provides no fault tolerance.RAID 3, also known as disk stripping with a parity disk, provides fault tolerance by writing data across three or more drives. Because the least number of hard disks is required, RAID 1 will be used instead of RAID 3.
Can two sata hard disk be used as without using raid?
Yes!
Is a group of two or more integrated hard disk that acts like single hard disk?
It is called RAID (redundant array of inexpensive disks).
What are RAID 1 and RAID 5?
Raid 1 suppports the Mirroring if any one hard disk faild one will get the copy of the data and fault tolerent. after replacing the hard disk you have to re create the mirroring. Raid 5 supports stripped with parity the data will be deviced into blocks and stored in all the drives with the parity information. if any one or two hard disks faild the data will be available.
How can I get an extra hard drive to mimic and copy my computer hard drive in tandem while using my computer?
It's called a "raid" disk controller. Using a raid controller you can connect 2 or more hard drives in a number of different configurations; one being that the drives are "mirrored".
When two hard drives are configured as a single volume its called?
Disk Spanning (raid 0)
What tool can you use in Windows to configure and manage hard drives and RAID levels?
Disk Manager
What is the purpose of scsi and raid adapter?
to connect storage devices such as hard disk drives to a PC
