Four to three
In the IB-RD3640SU3E2 four 3.5" hard disks can be connected at the same. All hard disks are connected either via the USB 3.0 port, eSATA or the FireWire 800 interface to the PC.

A hot tip
Installing, replacing and working with the HDDs is done in a breeze. HotSwap and Plug & Play make sure of that.In order that the heat created by the HDDs will not be too hot, a temperature controlled fan is built into this enclosure. The aluminium dissipates the rest of the heat to the outside of the enclosure passively too.

no capacity limits
Even though only HDDs with the maximal height of 8.9 cm fit in the slots, their capacity has no limit at all. The supported RAID modes are RAID 0, 1, 3, 5, 10 and Single. So the user have total freedom to set up the system to his specific needs.

IB-RD4320StUS2 - Device switches off after a few seconds

Question: Why turn on the IB-RD4320StUS2 few seconds after switching off by itself?

Answer: Please verify that the IB-RD4320StUS2 is properly connected to your PC. This is a normal behavior of the device when it is not connected by a data cable to the PC. Please connect the USB 2.0 or eSATA cables.

Interesting facts about the new USB 3.1 standard
The USB interface has been the standard for PC hardware and the new USB 3.1 standard entails several improvements. Not only the data transfer rates are much faster but also the charging of smart devices. And finally, the reversible-plug connector is introduced to USB as well.

Compared to USB 3.0 the transfer rates are doubled, thus the USB 3.1 interface achieves speeds of up to 10 Gbit/s which makes the interface fast enough to even max out current SSDs.

Another novelty, the reversible-plug USB Type-C connector, can be plugged into an appropriate USB Type-C connector. Without worrying about its directions, it will fit either way. USB Type-C is able to connect monitors via its USB interface. At the same time, data can flow further using the very same USB port. Theoretically, the transfer rates should suffice to connect 5K monitors which are not yet widely-used.

On top of that the new Type-C connector allows the use of Power Delivery (PD). A feature which provides the possibility to charge devices using up to 100 Watt. Supposably, even notebooks could be charged via USB. In the near future it might even be possible for the new Type-C interface to become the new standard for smartphones, tablets and other smart devices because of the connector's small size.

The already well-established USB 3.0 interfaces Type-A and Micro-B will still be preserved for the future, though, and will also have transfer rates of up to 10 Gbit/s. Whether Type-C is completely going to replace the old-established USB interfaces is yet to be awaited. In the meanwhile, the compatibility between the old USB types and the new Type-C is ensured by already available USB adapters or a PCI-E expansion card. This way the new USB type remains compatible with older PCs or notebooks, even without having Type-C ports.
