Mirrored/
Mirroring
Provides redundancy by writing identical
data to each member disk of the array.
Parity
A type of data protection where redundant
information is calculated from actual data
values.
Physical Drive
The actual hard disk drive.
RAID
Redundant array of independent disks.
Redundant
Information
Technology
Additional computer components, such as
hard disk drives that are installed to back up
the primary storage disks in case of failure.
S-ATA
Serial Advanced Technology Attachment.
Standard used for serial signaling technol-
ogy and is used for connecting hard disk
drives.
Striped/Striping
A performance-oriented data mapping tech-
nique. Data written to the array are divided
into stripes and written across the disks of
the array.
