Hardware RAID that works seamlessly between Macs and PCs
A software RAID storage system is unable to overcome the problems associated with cross-platform usage. It is only through hardware RAID controller chipsets that users can use these hard drives concurrently in Mac or Windows computers. With the DR2's built-in hardware RAID controller chipset and Thunderbolt™ 3 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. (RAID storage is used between Mac OS and Windows PC platforms and needs to use the same file format, for example: exFat file format).

The DR2-TB3 is equipped with three configuration modes to suit every need

The DR2-TB3 has three built-in disk configuration modes: RAID 1 (Safe Mode), RAID 0 (Speed Mode), JBOD (Two Independent Volumes) 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.

Thunderbolt™ 3 (USB-C) brings you 40Gbps extreme high data transfer speed

DR2-TB3 supports Thunderbolt™ 3.0 (TB3) interface for an extreme high data transfer speed.  And both of the two TB3 ports are equipped with a up to 40Gb/s data transfer rate which is 4 times faster than USB 3.1 Gen 2 ,2 times faster than Thunderbolt™ 2.0 and even 8 times than SATA III interface.  You could definitely use it to play your 4K high-resolution films with no any lagging hassle.  Thunderbolt™ 3.0 interface not only brings you this high data transfer rate advantage, it also let you chain maximum up to another 6 more DR2-TB3 products (or other compatible storage products).


All Thunderbolt™ 3 products should be connected to the Thunderbolt™ 3 PC/Mac host. It cannot be connected to the host only with USB-C interface. Please refer to the following explanation.  

DR2-TB3 to support both of 3.5" HDD and 2.5" HDD & SSD products
