Create a RAID
NOTE
The T4 comes formatted as a RAID 0 using Apple’s HFS+ le system. Windows
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 oer
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 oers 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 rst drive in the SPAN set is lled, data then gets saved to the following drive.
SPAN does not oer any performance gains but is useful when using drives of dierent capacities.
It is highly recommended to have a backup when using SPAN because it does not oer any form
of data protection.
