1.5 RAID MODE
1.5.1
Disk Striping (RAID 0)
Striping is a performance-oriented, non-redundant data mapping technique. While Striping is discussed as
a RAID Group type, it is does not provide any fault tolerance. With modern SATA and ATA bus
mastering technology, multiple I/O operations can be performed in parallel, enhancing data throughput.
Striping arrays use multiple disks to form a larger virtual disk. The figure below illustrates a three-disk
stripe set. Stripe one is written to disk one, stripe two to disk two, and so forth. RAID 0 sets can be
comprised of two, three, or four drives. If the sizes of the disk segments are different, the smallest disk
segment will limit the overall size of the RAID Group.
Stripe0
Stripe1
Stripe2
Stripe3
Stripe4
Stripe5
Stripe6
Stripe7
Stripe8
Stripe9
Stripe10
Stripe11
1.5.1
Disk Mirroring (RAID 1)
Disk mirroring creates an identical twin for a selected disk by having the data simultaneously written to
two disks. This redundancy provides instantaneous protection from a single disk failure. If a read failure
occurs on one drive, the system reads the data from the other drive. RAID 1 sets are comprised of two
drives, and a third drive can be allocated as a spare in case one of the drives in the set fails. If the sizes of
the disk segments are different, the smallest disk segment will limit the overall size of the RAID Group.
Block 0
Block 1
Block 0
Block 2
Block 1
Block 3
Block 2
Block 3
1.5.2
Concatenation (Spanning)
The Concatenated mode combines multiple disks or segments of disks into a single large volume. It does
not provide any data protection or performance improvement but can be useful for utilizing leftover
space on disks. Concatenation allows the segments that make up the volume to be of different sizes.
1.5.3
Contiguous (JBOD/Single Drive/Segment)
The single drive is a virtual disk that can either be an entire disk drive or a segment of a single disk drive.
Single drive is the “Contiguous” configuration option when creating RAID Groups (or sets) in the
SATARAID5 software.

CONFIGURATION
3.1 CONFIGURATION PREREQUISITES
3.1.1
SATA HOST CONNECTIONS
This guide assumes that you have already attached the TR2UT to a host computer that
has been installed with the Sii3124 or Sii3132 HBA (Host Bridge Adapter) or another third
party SATA HBA with Port Multiplier (PM) support.
If you use a host controller that does not provide Port Multiplier support, the JBOD RAID
mode is unavailable when configuring the TR2UT. Only one disk is available on the host
computer.
3.1.2
USB HOST CONNECTIONS
If you are connecting your TR2UT using a USB connection to your host, the USB port
should be compliant with USB 1.0, 2.0 or connected to a USB hub.
3.2 CHANGING HOST CONNECTIONS
The TR2UT supports both USB and eSATA host connections, although only one connection can
be attached at any given time. For the best data transfer performance, you should always use the
eSATA host connection.
If it becomes necessary to change the host connection between eSATA and USB, the host
computer system and the TR2UT should both be powered down prior to making the host
connection change to avoid any potential data loss or corruption. After changing the host
connection, all items can be powered-up to resume operation with the new host connection.
3.3 DISCONNECTING A USB DEVICE
USB 2.0 external devices provide support for “plug & play” connection, so that your USB storage
device can be connected and disconnected while the computer is running. To prevent data loss
or other failures, you must follow these steps when disconnecting your USB 2.0 storage device
from your host computer system. Once the physical USB device is disconnected, any volumes
that are associated with that device will become unavailable. On O/S (Operation Systems), the
TR2UT must be stopped from O/S before any devices can be disconnected.
3.3.1
WINDOWS SYSTEMS
1. Click on the Eject icon (a small green arrow over a hardware image) in the System
Tray located in the lower right-hand side of your screen.
2. A message will appear listing all of the devices that the Eject icon controls. Click on the
“Safely remove USB Mass Storage Device” item.
3. The following message then appears: “Safe to Remove Hardware”. You can now safely
disconnect the device from your computer.
Note: If your host USB adapter does not support this feature, the device should be
disabled using the Device Manager or your system should be shut down cleanly
and powered off before disconnecting the USB device.
3.3.2
MACINTOSH SYSTEMS
You must un-mount the hard drive system by dragging the hard drive icon to the trash before
disconnecting it or powering it down.
3.4
HARD DISK DRIVE HOT-PLUG & UNPLUG
When using a SATA host connection, the hard disk drives can be hot-plugged or hot-unplugged
while the system is running. However, to avoid data corruption or loss, care should be taken to
ensure that the host system is not currently using any drive that is about to be hot-unplugged.
When using a USB host connection, the hard disk drives should not be hot-plugged or hotunplugged while the system is running. Instead, you should eject the drives or shut down your
host system before connecting or disconnecting any hard disk drives.
3.5 LED INDICATIVE STATUS
TR2UT provides information on the SATA HDDs, System Alarm, USB Host, eSATA Host, and
Power LEDs.
Each LED activity will turn On/Off the LED for approximately 70 ms. The blinking rate is
approximately 400 ms On and 400 ms Off.

3.6 MODE SETTING
The TR2UT with the device’s LEDs to indicate status. To select a RAID mode in this mode the
first time that a new factory-shipped product is used, ensure that the hard disk drives are installed;
turn on the power before set the DIP switch on the back of the TR2UT to the desired RAID mode.
To change the RAID mode thereafter, set the DIP switch to the desired position and press the
recessed Mode Change push-button to create the new virtual volume(s). Creating new virtual
volumes will destroy any existing data that existed on the previous volume, but expanding an
existing COMBINE (BIG) volume will not destroy any existing data.
3.6.1
STANDARD (INDIVIDUAL) MODE
IMPORTANT: Before reconfiguring a volume, back up your data and delete
previously defined partitions.
1. Turn on the power.
2. Set the DIP switch position to STANDARD.
3. Press the recessed Mode Change push-button.
3.6.2
COMBINE (BIG) MODE
IMPORTANT: Before reconfiguring a volume, back up your data and delete
previously defined partitions.
1. Turn on the power.
2. Set the DIP switch position to COMBINE.
3. Press the recessed Mode Change push-button.
3.6.3
STRIPING (FAST) MODE
IMPORTANT: Before reconfiguring a volume, back up your data and delete
previously defined partitions.
1. Turn on the power.
2. Set the DIP switch position to STRIPING.
3. Press the recessed Mode Change push-button.
3.6.4
MIRRORING (SAFE) MODE
IMPORTANT: Before reconfiguring a volume, back up your data and delete
previously defined partitions.
1. Turn on the power.
2. Set the DIP switch position to MIRRORING.
3. Press the recessed Mode Change push-button.
Note: After you have pressed the Mode Change push-button, the MIRRORING mode will
start to rebuild. (The rebuilding time depends on the capacity of HDD.) Once the
rebuilding has completed, the HDD indicative LEDs will turn RED then to GREEN
color.

FAQ
If you need some help for troubleshooting, please check the frequently asked question below, it
may help you problem solved quickly
•
Can not recognize
Make sure all cables have been connected properly.
•
Can not operate in O/S
Make sure the O/S is support for the product.
•
Transmission speed is slow
If connect USB1.1 interface, the speed will be around 1MB/sec only.
•
When format in the Windows 2000/ XP/ Vista/ Server 2003, the dialog box appear
“Unfinished formatting”
Windows 2000/ XP/ Vista/ Server 2003 can not format HDD over 32GB by FAT32,
Please format by NTFS.
•
When using different capacity or brand HDD, can we still using COMBINE mode?
Yes
•
When system is damaging on COMBINE mode, is it possible to keep the data?
No. The system is different with RAID. That’s because the filed of HDD data combine, It
may be read from disk has the data in the front. The “Sample 1” image below, it takes out
only disk 2, and it may read the data from disk 1. The “Sample 2” image below, the entire
disk can not be read.
