The CADA-SA2-Black Series offers an unbeatable combination of
RAID data protection, 3.0Gbit/sec eSATA speed and a vast storage
capacity of 2 TB (1 TB mirrored). This dual-bay disk array
features swappable hard disks and a built-in RAID controller. The
unit arrives preconfigured in RAID 1 to protect your important
data - if one drive fails, replace it with an identical drive and
the data will automatically rebuild. Leave it in RAID 1 mode for
automatic background rebuilding and optimum security for your
files, or configure to RAID 0 for increased data reading and
writing speeds. Factory default is RAID 1 GUI mode, but also
supports RAID levels 0, 1 and 0+1(safe 33/safe 50). Its SATA
interface provides a faster boot process and quicker loading of
programs and data. Ideal for saving hefty files, video, music,
protecting databases or working directly on the drive, it
delivers high-capacity performance and data security. The unit is
factory pre-configured in RAID 1 and ready to use out of the box.
Install the easy-to-use RAID configuration software and the
included SATA to eSATA bracket kit to take full advantage of the
incredible set of features.
