TeraStation User Manual 19
• RAID 1 mode (Default for TS-WXL/R1)
Uses 2 hard drives as one array. You can use up to 2 arrays on TS-XL, TS-XEL and TS-RXL Series. The space you can use
is 1 hard drive’s space for each array. The same data is written to 2 drives at once. If a drive is damaged, data can be
recovered by replacing the damaged hard disk. If both drives in an array are damaged, data cannot be restored. You
can create an array and designate another drive as a hot spare (which will boot automatically when one of the hard
drive fails) in TS-XL and TS-RXL TeraStations. You can use 2 drives to create a RAID 1 array, use anther drive as a hot
spare, and use another as a regular drive, all at once.
• RAID 0 mode
This mode uses multiple hard drives as a single array. The disk space you can use is the total space of all hard drives
used. This is the fastest of the TeraStation’s RAID modes. If any hard disks are damaged, you cannot recover data.
• Normal Mode (Default for TS-WXL/1D)
This mode uses the hard drives inside the TeraStation as individual hard disks. It is sometimes referred to as JBOD. The
disk space you can use is the total space of all hard drives in the TeraStation. If a hard disk is damaged, you cannot
recover data from that drive.
Note:
During a recovery, the TeraStation’s front LED display shows “RAID ARRAY* Resyncing” and le transfer speeds are
slower than usual until the RAID array is rebuilt.
