DRD-501
FIVE-BAY RAID SYSTEM
FOR 3.5” SATA HARD-DISK DRIVES
USER MANUAL
2
Thank you for choosing Xcellon.
The Xcellon DRD-501 Five-Bay RAID System is a convenient solution for large-data storage
needs, housing up to five internal-type SATA hard-disk drives. Instead of dismantling your
computer and installing the disk drives, you simply insert the drives into the enclosure and
attach it to your computer via one of the included high-speed connection cables.
The DRD-501 is compatible with 3.5" I/II/III hard-disk drives, and oers seven RAID modes for a
variety of options when it comes to read/write functions, data storage, and backup.
The DRD-501 features a USB 3.0 port, an eSATA port, two FireWire 800 ports, and a FireWire
400 port for flexible connectivity. The enclosure can attain maximum transfer rates of up to
5.0 Gbps via the USB 3.0 port, which supports plug-and-play. The DRD-501 also supports
hot-swapping of disk drives. A large internal fan for ecient cooling prevents the drives from
overheating.
The DRD-501 includes all necessary interface cables and is compatible with both Windows
and Mac operating systems.

Getting Started
1. If necessary, use the included hex key to unlock and open one of the HDD doors.
2. Align the SATA contacts on your disk drive with those in the enclosure, and fully insert
the drive into the enclosure.
3. Close the HDD door all the way so it latches into place, and use the included hex key to
lock the door.
4. Repeat steps 1 through 3 for your other hard disks, as desired. The DRD-501
accommodates up to five hard-disk drives.
5. Configure the desired RAID mode (see RAID Mode Configuration on page 8).
6. Select the cable you want to use from among the included interface cables and use it
to connect the DRD-501 to the corresponding port on your computer.
7. Align the pins in the DC power supply’s cable with the pins in the DRD-501’s DC power
port, and plug the DC power supply into the DRD-501.
8. Use the included AC power cable to plug the DC power supply into an AC power source.
9. Press the power button to turn on the DRD-501. As the DRD-501 turns on, it will emit
a beep and the HDD status LEDs will glow blue.
If your disk drives have been formatted, your computer will notify you that new hardware has
been detected, and the drive will appear on the Desktop, in My Computer, or in the Finder.
If the drives have not been formatted, or if your computer cannot read or recognize them, you
may need to format the drives (see Formatting Your Disk Drive for Windows OS on page 11
and for Mac OS on page 21).
When the disk drives are connected, the HDD status LEDs will glow blue. During disk read/
write operations, the HDD status LEDs will blink red and blue. After approximately five minutes
of inactivity, the disks will enter sleep mode, and the HDD status LEDs and the fan will turn
o.

RAID Mode Configuration
The DRD-501 oers several RAID modes that read/write and handle data dierently. We
encourage you to familiarize yourself with the advantages of each RAID mode before making
a selection.
Before configuring the RAID mode, make sure to back up
your data. All data on the installed disk drives will be deleted
during the configuration process.
!
Make sure that all drives have the same rotational speed (RPM).
It is recommended that all hard drives have the same capacity. If possible, use identical drives.
RAID 0
RAID 0 mode stripes data in blocks across the disk drives installed in the enclosure. This
mode links all the drives installed in the enclosure, so they can function as a single drive with
combined storage space. For example, if you are using five 100 GB drives, they will combine to
function as a single 500 GB drive.
RAID 1
RAID 1 mirrors the data in blocks on two disk drives installed in the enclosure, so the exact
same data is stored on both drives. Data integrity is more reliable in this mode than in RAID 0
mode, although there is less accessible disk space and the transfer speed is slower. Mirroring
makes it easier to recover lost data if one of the RAID drives is damaged. Only one of the two
drives is accessible in RAID 1 mode.
When two disks are inserted and the RAID mode switches are set to RAID 1/10 configuration,
the enclosure will be set to RAID 1 mode.
When using RAID 0 and RAID 1 modes, you can use disk drives of varying capacities, although
the capacity will be limited to the smallest of the disk drives. For example, if you are using a
100 GB and a 250 GB drive, then the 250 GB will be limited to the smaller 100 GB capacity,
and the total combined capacity will be 200 GB.
9
RAID 10
RAID 10 mode creates two RAID 1 mirrors, and then a RAID 0 system to stripe data across
them in blocks. This mode, which requires four disk drives, oers the striping of RAID 0 with
the full redundancy and reliability of RAID 1. In RAID 10 mode, you will have access to a
combined two-drive RAID 0 system. For example, if you are using four 100 GB drives, you will
have access to a 200 GB RAID 0 system.
When four disks are inserted and the RAID mode switches are set to RAID 1/10 configuration,
the enclosure will be set to RAID 10 mode.
RAID 3
RAID 3 stripes data in bytes across all the disk drives installed in the enclosure, with one of the
drives dedicated for parity data. Parity makes it easier to recover lost data if one of the RAID
drives is damaged. In this mode, the maximum accessible capacity will be the total number of
drives, minus one drive.
RAID 5
RAID 5 stripes data in blocks with parity across a minimum of three drives. This mode is similar
to RAID 0, but with parity data distributed among the drives installed in the enclosure. In this
mode, the maximum accessible capacity will be the total number of drives, minus one drive.
Like RAID 0 and RAID 1 modes, RAID 5 mode is compatible with drives of dierent capacities,
although the capacity will be limited to the smallest of the disk drives. For example, if you are
using two 100 GB drives and a 250 GB drive, then the 250 GB will be limited to the smaller
100 GB capacity, and it will be as if you are using three 100 GB drives. The total amount of
accessible storage space will be 200 GB.
Normal (JBOD)
In Normal mode, all the disk drives installed in the enclosure function independently of one
another. This mode is informally referred to as Just a Bunch Of Disks (JBOD).
10
Span (Big)
Span mode links all the disk drives installed in the enclosure, so they can function as a single
drive with combined storage space. This mode is similar to RAID 0 mode, but it does not stripe
the data.
There are two ways to configure the RAID mode—via the included software or hardware. To
configure the RAID mode via software, use the included RAID configuration software.
To configure the RAID mode via hardware, follow these steps:
1. Make sure the DRD-501 is turned o.
2. Clear the current RAID mode by pushing the RAID mode switches into the up position.
3. Press and hold the Set button. While holding the Set button, press and release the
Power button to turn on the DRD-501. The DRD-501 will emit a beep as it turns on.
Continue holding the Set button until you hear a second beep.
4. After the DRD-501 emits the second beep, release the Set button and press the Power
button again to turn o the unit.
5. Set the RAID mode switches to the desired configuration, as shown in the image below:
6. Press and hold the Set button. While holding the Set button, press and release the
Power button to turn on the DRD-501. The DRD-501 will emit a beep as it turns on.
Continue holding the Set button until you hear a second beep. At this point, the DRD-
501 will be recognized in the reconfigured mode.
After reconfiguring the RAID mode, you will need to format. You may also need to initialize
your disk drives.
