Create a RAID
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 T3 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.
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.
NOTE
The T3 comes formatted as a software RAID 0 using Mac’s HFS + file system.
Windows users must recreate the RAID in the T3 using Window’s disk
management software using the NTFS format. Creating a RAID will delete
any information on the hard drives so make sure to back up all your data
before proceeding.
