RAID levels Function/Applications Advantages/Disadvantages
RAID 0
Function:
Data is distributed across
both disk drives.
Applications:
●
Image editing
● Video production
●
Pre-press applications
Advantages:
Read performance is
higher than that of a non-
RAID HDD.
Total storage capacity is
doubled.
Disadvantages:
The entire array fails if one
drive fails; data cannot be
recovered.
Storage space may be
wasted if the capacities of
the primary and recovery
HDDs are different (see
HP
SATA drive option kits
on page 7).
RAID 1
Function:
Identical (mirrored) data is
stored on two drives.
Applications:
●
Accounting
●
Payroll
● Financial
Advantages:
Provides high fault
tolerance.
Disadvantages:
Only half of the total drive
capacity can be used for
storage.
Storage space may be
wasted if the capacities of
the primary and recovery
HDDs are different (see
HP
SATA drive option kits
on page 7).
