SHARKOON 5-Bay RAID-Station - Manual (Page 32)

5-bay raid station 32
11.4 R0 mode
Function:
In R0 mode the data is spread across all hard disks.
Advantage/disadvantage:
R0 mode represents the best data speed but no data redundancy. R0 mode accelerates
hard disk drive operating speed by using many disks simultaneously. Hard disk drive data
segments are written to different disks, which increases performance.
To implement the R0 mode storage policy, the 5-BAy RAID STATION creates a single
virtual volume that is striped across all hard drives, with a storage capacity that is five
times the capacity of the smallest drive.
11.5 R1 mode
Function:
In R1 mode all data is duplicated on separate drives to protect against data loss due to
drive failure. One drive mirrors the other at all times. Every write operation addresses
both drives.
Advantage/disadvantage:
R1 mode provides the highest level of data protection for critical data.
The resulting storage capacity of the virtual R1 volume will be equivalent to the size of
one hard drive (if both drives are of the same size) or the smaller of the two drives (if they
are of different size).
