The IB-2253RD-U31 is a RAID system for two 2.5" SATA III hard drives or SSDs. The RAID modes 0, 1, single, and LARGE are supported and can be set up easily using the switch on the back.

USB 3.1

USB 3.1

The USB port has become a standard for PC hardware and the new USB 3.1 standard brings some improvements, such as a transfer speeds of up to 10 Gbit/s. However, the known USB interfaces type-A and Type-B remain with us still and they will be able to reach the USB 3.1 speed with the proper support. The RAID system includes both a USB Type-C™ and USB Type-A cable for maximum compatability with different devices.

Cool passion

The aluminum grid helps in dissipating the heat generated and so the case keeps the HDDs cool even wihtout the use of a fan. Additionally the LEDs indicate operation, use, access and errors of the installed hard disks.

Data sheet


Compatibility with the host computer
For USB 3.0 and 3.1 enclosures from ICY BOX, make sure that the corresponding USB port is available on your host computer. Although our enclosures are always USB downward compatible, please note that the specified data transfer rates cannot be achieved with an older USB version.
Are cables included in the package content?
All our ICY BOX enclosures are supplied with cables. Whether integrated in the enclosure or included, the cables are always part of the ICY BOX enclosure.
If you want to connect a USB Type-C® enclosure to a USB Type-A connector, it is possible to use an adapter from ICY BOX (IB-CB015). The same works in the other direction from USB Type-A to USB Type-C® (IB-CB003).
Up to which hard disk capacity can I equip the ICY BOX?
The capacity of all our enclosures is unlimited.
Can a HDD be removed from an external HDD and installed into an ICY BOX?
Only conditionally. It is possible that HDDs purchased in combination with enclosures have special firmware that prohibits operation in other external enclosures (e.g. ICY BOX) or only allows operation in special enclosures. We recommend to equip our external ICY BOX enclosures with conventional drives, which can be purchased separately on the market.
Are special drivers required?
No, only the standard USB drivers are required, which are already pre-installed on your system by default. Please make sure that the USB drivers are up to date.
Can the enclosure also be connected to USB 2.0 ports?
Yes, this is possible. Please note, that the data transfer rates are much lower in this case.
Do I need a power supply for my external 2.5" enclosure?
An additional power supply for your 2.5" enclosure is usually not required. However, some of our external cases do have a 5 V connection to which you can connect an external power supply if required. An external power supply is not included.
Why is the HDD/SSD not recognized?
Make sure your HDD/SSD is correctly connected to the external enclosure and its connectors.
If the HDD/SSD is new, it must first be correctly formatted and partitioned before it is displayed in the system.
Use a different USB port on your notebook or PC.
Check if the power supply is connected and the external enclosure is switched on with the on/off switch (only for 3.5" enclosures).
Update the USB 3.0 / USB 3.1 drivers of your notebook/PC or mainboard. Current USB drivers can be found on the website of your mainboard manufacturer.
Everything is connected, but no function.
To avoid possible problems, there are some quick tests that you can perform. You can test if the following components work correctly and are not the source of the problem:
- Cables
- Enclosure
To test your components, proceed as follows:
- Use the cables, hard drives, and enclosures on another system to see if your system is the source of the problem.
- Use a different cable, HDD/SSD, and hard disk enclosure one after the other to see if the problem persists. Ideally, you should test a component that you know works in a different setup.
Where can I find drivers for my device?
If drivers or firmware updates are available for your device, you can find them on the ICY BOX website by clicking on the download button below the corresponding product picture.Alternatively, you can also search for the desired product via the support tab in the search field and then click on the firmware button. However, if you are using a current operating system, it will rarely be necessary to install drivers at a later date.
Why is the built-in fan so noisy? (Not all devices do have a fan.)
The built-in fan is automatically controlled by a thermal sensor. However, you can also control the fan manually.
Can I install another fan?
Yes, you can replace the existing fan with an identical fan. For the exact specifications of the fan, please refer to the data sheet of the product.
Why is the SOHO/RAID system not recognised?
Make sure that your HDD/SSD is correctly installed in the SOHO/RAID enclosure.
Check if the power supply is connected and the SOHO/RAID enclosure is switched on with the on/off switch.
Check if the SOHO/RAID enclosure works on another USB port or connect it with another USB cable.
Update the USB 3.0 / USB 3.1 drivers of your PC or mainboard. Current USB drivers can be found on the website of your mainboard manufacturer.
Update the SATA host drivers of your mainboard.
Can I connect my device via the USB and eSATA interfaces at the same time?
No, only one interface at a time can be used.
Where do I find drivers for my device?
You can find the latest drivers for your device in the Download Centre in the Support category. If you are using an up-to-date operating system, however, it will rarely be necessary to install drivers subsequently.
Can hard disks with a capacity of more than 2 TB be used?
Yes, under Windows® you have the option to activate the GPT option to initialise and format hard disks larger than 2 TB. You can find more information on using GPT at:
Mac® user can only use hard disks with more than 2 TB from the Tiger 10.4.11 operating system or higher.
Why does the device switch to stand-by mode automatically?
The unit automatically switches to stand-by mode when the interface cables (USB/eSATA) are removed and the SYNC switch is set to ON.
Why is the built-in fan so loud? (Not all units have a fan)
The fan installed in the SOHO/RAID system is automatically controlled by a thermal sensor. However, you can also control the fan manually.
Can I install a different fan in my SOHO/RAID system?
Yes, you can replace the existing fan with an identical fan. Please refer to the product data sheet for the exact specifications of the fan.
Which functions do the different RAID levels offer?
JBOD (RAID 0 Spanning)
Spanning connects several drives to one large virtual drive and thus bypasses the physical limitation of individually connected drives. The data is written continuously from drive 1 to drive 2. This is not a SINGLE JBOD.
Configuration of a RAID controller with several drives that do not form a group. This makes the connected drives available to the operating system individually.
RAID 0 (RAID 0 Striping)
Striping combines several drives into one large virtual drive as one logical unit. The data is written to all drives in parallel, which leads to an increase in the data transfer rate. However, if one drive fails, all data is lost.
RAID 1 (RAID 1 Mirroring)
Mirroring is the automatic mirroring of data on several drives. This ensures a high level of data security. If one drive fails, access is still possible and after replacing the defective drive, the data mirror is restored. The usable memory corresponds to the capacity of the smallest drive used.
A RAID 5 is a group consisting of at least three drives. Data is distributed to all drives and these are additionally equipped with parity information. Thus, even in the event of a failure, all data can be accessed and the defective drive can be replaced. RAID 5 therefore offers increased fail-safety.
