Create A Raid - CalDigit T4 User Manual

Create a RAID

The T4 comes formatted as a RAID 0 using Apple's HFS+ file system. Windows
NOTE
operating systems are not currently supported.
Striped RAID Set - RAID 0 - distributes data evenly across all drives in RAID 0. Use this mode
for increased performance. RAID 0 provides no protection against drive failure. It is highly
recommended to have a backup when using the T4 in RAID 0.
Mirrored RAID Set - RAID 1 - creates identical copies of data across all drives in the RAID 1 volume.
RAID 1 is ideal for back up and archiving. This is the most secure form of RAID but does not offer
any performance increase.
Parity Striped RAID Set - RAID 5 - creates identical copies of data across all drives in the RAID 5
volume. Users that require a combination of performance and protection will opt for RAID 5. RAID
5 offers single drive redundancy along with the performance of a striped set. In the unlikely event
of a single drive failure, the data will remain intact and accessible.
Concatenated Disk Set - SPAN (non-RAID) - drives work together but data is not distributed
evenly. After the first drive in the SPAN set is filled, data then gets saved to the following drive.
SPAN does not offer any performance gains but is useful when using drives of different capacities.
It is highly recommended to have a backup when using SPAN because it does not offer any form
of data protection.
