RAID 1 is also known as disk mirroring. This is a pair of disk drives that store duplicate data, but appear to the computer as a single drive. All writes move to both drives of a mirrored pair so that the information on the drives is kept identical. However, each drive can perform concurrent, independent read operations. Mirroring therefore doubles the read performance of a single nonmirrored drive, while the write performance is unchanged. RAID 1 delivers the best performance of any redundant array type.
