ICY BOX IB-3640SU3 USB 3.2 Gen 1 (3.1 Gen 1) Type-B Sort

No more "Double Trouble"
In case two HDDs are not enough: In this wonderful JBOD (=Just a bunch of disks) enclosure, four 3.5" HDDs can be mounted. Without using any screws, the HDD can be mounted and replaced. Even while in operation.

The smart fan
The fan has a quick reaction when the temperature changes inside the enclosure. This way, your important data is constantly protected against heat. In case you would like to set it manually, you can still set it on one of the three available fan persets.

For the environment
If the host cable (USB 3.0 or eSATA) is not connected, or when the device is not being used it turns itself into Standby mode automatically. In addition, each HDD has an LED indicator in order to provide information regarding HDD activity (read/write), fan settings and connection.
