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 ZR2’s built in 2 x M.2 SATA converter hardware RAID controller chipset and USB 3.2 Gen 2 host interface, it not only promise high transmission speed, but 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.


ZR2-B31BP provides two power input methods: USB Bus-powered and Direct Current (DC)

ZR2-B31BP provides two power input methods: USB Bus-powered and Direct Current (DC). Users can adjust the power input method according to own needs.

A graphical user interface (GUI) software solution that allows for monitoring the status of the RAID configuration


The RAIDGuide Manager monitoring program delivers real-time monitoring of RAID module and hard drive statuses, enabling users to easily assess system performance.

The ZR2-B31BP is equipped with four configuration modes to suit every need
The ZR2-B31BP has four built-in 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.


RAID 1 function provides fully automatic backup that ensures data security.
RAID 0 function increases storage speed and performance.
JBOD function provides two independent disk data access convenience.
BIG function provides two independent disk capacity added total.

Support host computer with Type-C and Thunderbolt™ 3 (USB-C)


ZR2-B31BP is equipped with RAID system and supports host computers with Type-C and Thunderbolt™ 3 (USB-C), ZR2-B31BP compatible with all USB 3.2 Gen 1,2/2.0 specifications.


Users can use the USB 3.2 Gen 2 Type-C to C cable of ZR2-B31BP to connect to the USB Type-C or Thunderbolt 3 (USB-C) interface of Macbook Pro or iMac Pro, or connect to the PC or laptop with USB Type-C interface, it transfer speeds up to 10Gbps.

The new ZR2-B31BP have the manual fan adjustment that users can adjust the fan speed to high speed or low speed.  User does not need to worry about the fan sound to disturb the work environment, and the device can be still working efficiency. 

JBOD Independent M.2 SATA SSD Data Exchange


If your project files are too large to be transmitted via the internet, or you need to send the same data out for use with different devices, such as editing photo or video files up to 500G ~ 750G, the design of removable hard disk tray is perfect for your requirements. In the independent mode of ZR2-B31BP, each M.2 SATA SSD can be work independently, just like an independent database. You can qucikly change the library you need, and back up your important data offsite to meet the various needs in the different computer environments.


Just to use ZR2-B31BP for data backup
You can also easily extend your legacy device with Thunderbolt™ 3 (USB-C) interface, which connects to a Macbook Pro device with Thunderbolt™ 3 (USB-C) interface. Your Macbook Pro could connect to one ZR2-B31BP for a huge memory storage capacity thru its high performance Thunderbolt™ 3 interface.  You could definitely enjoy its huge memory capacity together with the RAID 1 for an excellent data protection.

RAID 0 mode, Help you to achieve various photos editing 


Since ZR2-B31BP provides USB 3.2 Gen 2 port, just use your MacBook Pro with Thunderbolt™ 3 (USB-C) interface, you could set up your own full function photo studio and could save tons of RAW images at any time. And you could edit and browse the large images database quickly when set up the RAID 0 mode. (Using SSD, the measured Write is about 824MB / Read is about 638 MB, the performance will be vary depending on the environment). 

Performance test result for reference. The test result will vary depend on the test environment.


This product is capable of achieving data transfer speeds of up to 10 Gbps when operated on a PC running the Windows operating system. However, it should be noted that the performance is reduced to 5 Gbps when used with systems powered by the current Apple M1 or M2 processors.
