Term Description
Migration The process of converting a system's data storage configuration from
a non-RAID configuration (pass-thru) to a RAID configuration.
Hot Plug The unannounced removal and insertion of a Serial ATA hard drive
while the system is powered on.
NCQ Native Command Queuing: a command protocol in Serial ATA that
allows multiple commands to be outstanding within a hard drive at
the same time. The commands are dynamically reordered to increase
hard drive performance.
On Request Update
Policy
When a recovery volume is using this policy, data on the master drive
is copied to the recovery drive when you request it. Only changes
since the last update process are copied.
OS Operating System
Port0 A serial ATA port (connector) on a motherboard identified as Port0.
Port1 A serial ATA port (connector) on a motherboard identified as Port1.
Port2 A serial ATA port (connector) on a motherboard identified as Port2.
Port3 A serial ATA port (connector) on a motherboard identified as Port3.

RAID Redundant Array of Independent Drives: allows data to be distributed
across multiple hard drives to provide data redundancy or to enhance
data storage performance.
RAID 0 (striping) The data in the RAID volume is striped across the array's members.
Striping divides data into units and distributes those units across the
members without creating data redundancy, but improving read/write
performance.
RAID 1 (mirroring) The data in the RAID volume is mirrored across the RAID array's
members. Mirroring is the term used to describe the key feature of
RAID 1, which writes duplicate data to each member; therefore,
creating data redundancy and increasing fault tolerance.
RAID 5 (striping with
parity)
The data in the RAID volume and parity are striped across the array's
members. Parity information is written with the data in a rotating
sequence across the members of the array. This RAID level is a
preferred configuration for efficiency, fault-tolerance, and
performance.
RAID 10 (striping and
mirroring)
The RAID level where information is striped across a two disk array
for system performance. Each of the drives in the array has a mirror
for fault tolerance. RAID 10 provides the performance benefits of
RAID 0 and the redundancy of RAID 1. However, it requires four hard
drives.
RAID Array A logical grouping of physical hard drives.
