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 MR2’s built in SATA 6G hardware RAID controller chipset and USB 3.1 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.


The MR2-B31 is equipped with four configuration modes to suit every need
The MR2-B31 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.


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.

USB 3.1 Gen 2 brings you 10Gbps extreme high data transfer speed


With USB 3.1 Gen2 interface, the data transfer speeds can reach up to 10Gbps. Whether it is used for search and editing photo galleries, or for Macbook Pro (USB-C) video editing and synthesis, it promises smooth and easy operation.

Support USB Type-C interface, Plug and Play


The new MR2-B31 support the USB Type-C interface, which is based on the USB 3.1 Gen 2 specification, is designed to be identical in appearance. This means that users do not need to distinguish between the front and back sides of the USB, users can easily use the USB 3.1 cable to install, any both sides can be inserted.

Support 2.5" HDD & SSD products
MR2-B31 is equipped with two easy-to-install hard drive screwless trays, that can support any kinds of 2.5”SATA HDD/SSD. Also, it is designed with durable aluminum casing that is not only to protect your data but also for the excellent heat dissipation.
Since this new easy-to-use Tray is dimensional compliant to all our Stardom products, you could easily transfer your data among different storage devices.  And also, its key lock design could provide a double protection at your data from any improper Tray extracting.

Durable aluminum structure design with silent fan for excellent heat dissipation

MR2-B31 is made by the durable aluminum housing and designed with the 3cm silent fan (with safe FAN GUARDs) that help for the excellent heat dissipation with the long time use.

JBOD Independent Hard Disk 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 MR2-B31, each hard disk 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 MR2-B31 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 MR2-B31 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.

Help you to achieve various photos editing 


Since MR2-B31 provides USB 3.1 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).
