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 ST2-B31A’s built in SATA 6G 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.

The ST2 support Four RAID modes, can be used for Different Application

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.

Provide USB 3.2 Gen 2 Type-C to A cable 


ST2-B31A is equipped with RAID 0/1/BIG/JBOD modes, users can use the Type-C to A cable to connect to any host PC or Mac with USB Type-A, and the data transfer performance can be up to 10Gbps. Whether it isused for searching files, editing photos or watching the 4K high resolution videos, ST2-B31A will bring you the extremely enjoyment of video and audio quality.

ST2 support both 3.5" and 2.5" disks (HDD & SSD)

Comes with two easy-to-use disk Trays, ST2 supports 3.5" & 2.5" SATA disks (HDD and SSD). And ST2's aluminum chassis help protecting your data and the excellent heat dissipation. Since this easy-to-use disk Tray can be used for all STARDOM's products, you could easily transfer your data (disks) among different STARDOM's storage devices. With the key lock design, it could provide a double protection for your data.

LED Indicator for Disk Status Display

ST2-B31A provides the LED indicator for disk status display. When data accessing, the LED will flash light on, it allows user to understand the data access status quickly.

Low noise Fan, with manual fan speed control switch


The new ST2-B31A has a built-in low-noise fan, to allows the device to quickly dissipate heat without affecting the transmission perofrmance.

Rugged aluminum chassis design with high quality and fast heat dissipation

ST2-B31A's solid chassis is made by a thickness aluminum-alloy plate which can withstand greater impact than ordinary aluminum shell products, and it can really protect your hard disk and cope with various usage conditions. And its aluminum housing really help an efficient heat dissipation for your long time use.

Raid 1 Mode, use with Server to backup the important data

You can also use the Type-C to A cable to connect to a Server device with a Type-A interface. Using RAID 1 mode,  the ST2-B31A can be easily expand to be a personal storage center. Users do not need to worry about the hard drive damaged to lost the important data, and can achieve comprehensive data backup.

RAID 0 mode, complete various photo editing quickly 

ST2-B31A has an ultra-fast Type-C to A cable. Users can connect ST2-B31A to any host device that has USB Type-C to A interface. Using RAID 0 mode, the ST2-B31A can be created an entire photography studio to import or backup thousands of RAW images at any time, and help users to complete various photo editing quickly.
