Hardware RAID that works seamlessly between Macs and PCs
The new ST2-B31+ hard drive external storage is built-in Hi-Speed USB 3.1 Gen 2 transmission interface for Mac OS and PC OS. It provides Charging Port for maximum 24 watts (Power Delivery, PD)and a DP 1.1a Mini DisplayPort that allows users to the display screens which are compatible with existing DisplayPort screens, devices, and wiring that can be contacted with DVI, HDMI, and VGA screen via adapters. 


With the ST2's built-in SATA 6G hardware RAID controller chipset and USB 3.1 Gen 2 host interface, not only does it promise high transmission speed, it also eliminates the cross-platform usage issues associated with RAID 0 or RAID 1 setups. Also, with hardware RAID, all data is computed and processed by the built-in CPU. With such advantages, your computer performance can be focused on running the software and work, instead of handling the storage device's transmission issues.

The ST2 has four built-in disk configuration modes: RAID 1 (Safe Mode), RAID 0 (Speed Mode), JBOD (Two Independent Volumes) ,and BIG Mode for you to choose according to your needs.


The RAID 1 function provides fully automatic backup that ensures data security.


RAID 0 functionality increases storage speed and performance.


JBOD function provides two independent disk data access convenience.


BIG function provides two independent disk capacity added total.

USB 3.1 Gen 2 brings you an extreme high data transfer speed


The ST2-B31+ is equipped with BIG/JBOD/RAID 0/RAID 1 storage mode, which means users can attain up to 10Gbps speed with the ST2-B31+'s USB 3.1 transmission interface.
