The following settings changes are recommended.
Notes:
• By default, the TeraStation will attempt to use an NTP server to set the time.
• NTP may not be usable in some network environments.
• Read the terms of use for Internet Multifeed Co. at www.jst.mfeed.ad.jp. Internet Multifeed Co. is the group
that manages the NTP Server at www.jst.mfeed.ad.jp. Internet Multifeed Co. is not responsible for any loss or
damages caused by this service.
• BUFFALO is not responsible for any loss or damage caused by using of this service, stopping the service, or
missing service.
• If your TeraStation fails to automatically obtain the time from NTP Server, verify the settings for the DNS server
address of the TeraStation. You must set a primary DNS server address to specify an NTP server by host name.

Chapter 3
Changing RAID Modes
TS-XL, TS-XEL and TS-RXL series TeraStations default to RAID 5 mode (4 hard drives), TS-WXL/R1 series default to RAID
1 mode, and TS-WXL/1D series default to Normal mode. The characteristics of each type of RAID are described below.
If you change the RAID mode, all of the data on the hard drive is deleted. Always back up any important data before
changing the RAID mode.
Note:
In this document, the term “Recovery” means reverting the TeraStation back to the state prior to the drive error or RAID
mode change. It does not refer to reading data from failed hard drives.
• RAID 5 mode (4 hard drives) (Default for TS-XL, TS-XEL and TS-RXL)
Note:
TS-WXL/R1 and TS-WXL/1D TeraStations don’t support this mode, as they don’t have 4 hard drives.
Arranges 4 hard drives in one array. Parity is generated during writes, so access speeds will be slower than other RAID
modes. Total usable space is the sum of the 3 drives. If one of the drives fails, you can recover data on the array by
replacing the damaged drive. However, data cannot be recovered if 2 or more drives become damaged.
• RAID 5 mode (3 hard drives)
Note:
TS-WXL/R1 and TS-WXL/1D TeraStations don’t support this mode, as they don’t have 3 hard drives.
Arranges 3 hard drives in one array. Parity is generated during writes, so access speeds will be slower than other RAID
modes. Total usable space is the sum of 2 drives. A fourth drive may be congured as a hot spare that will automatically
replace a drive if it fails. If one of the drives fails, you can recover data on the array by replacing the damaged drive.
However, data cannot be recovered if 2 or more drives become damaged.
• RAID 10 mode
Note:
TS-WXL/R1 and TS-WXL/1D TeraStations don’t support this mode, as they don’t have 4 hard drives
Arranges 4 hard drives in one array, with 2 stripes of mirrored drives. Total usable space is the sum of 2 hard drives. Data
is written quickly and access speed is faster than other RAID modes (except for RAID 0). Since data is written into 2 hard
drives at the same time, even if one of the drives fails, data can still be recovered by replacing the damaged drive (data
cannot be recovered if both drives become damaged).
RAID Arrays

TeraStation User Manual 19
• RAID 1 mode (Default for TS-WXL/R1)
Arranges 2 hard drives in one array. You can set up to 2 arrays on TS-XL, TS-XEL, and TS-RXL series. Total usable space
is 1 hard drive’s space for each array. Data is written to 2 hard drives at once. If a drive fails, data can be recovered by
replacing the damaged drive (data cannot be recovered if both drives in the array become damaged).
You can create an array and designate another drive as a hot spare (which automatically replaces a failed drive) for TS-
XL and TS-RXL TeraStation models. You can also use 2 drives to create a RAID 1 array, use another drive as a hot spare,
and use another as a regular drive, all at once.
• RAID 0 mode
This is the fastest RAID mode, but if any of the drives fails, data cannot be recovered.
• 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.
