EW7077 Setup the HDD mode

The EW7077 default HDD mode is JBOD


Available HDD modes
• JBOD: Both drives are accessible as individual drives
• SPAN: Both drives are combined as 1 big storage drive.
• RAID0: Both drives are combined as 1 big storage drive similar to SPAN with the
difference the data is being split in 2 segments, segment 1 is stored on HDD1
segment 2 is stored on HDD2. This results in a higher bandwidth (making it
possible to get bandwidth speeds exceeding USB 3.2 gen1 when using 2x SATA
SSD).


Note! When you intend on using RAID0 and 1 of your hard disks fail to work your data
will no longer be available so DO NOT use this setup for important data only use this
setup to increase the bandwidth.


• RAID1: HDD 1 is cloned (mirrored) simultaneously to HDD2 providing a clone of
your HDD. This way when 1 of the 2 drives fail you still have your data secured on
the other drive. When replacing the failed HDD with a HDD with the same capacity
the data will again be cloned (mirrored) to the new HDD (cloning status is
indicated through the HDD LEDs flashing slowly, Cloning is ready when the
indicator LEDS stop flashing). If the capacity of the new HDD is not the same as
the current HDD the LED indicators will flash rapidly and data is not being cloned.


Note! When you intend on using hard disks with data already stored on the hard disks
the EW7077 will delete all data when you decide to change the HDD mode other than
JBOD. Please make sure you backup all the data on the hard disk before installing the
drives into the EW7077 enclosure.
