2-Bay 2.5”/3.5” SATA III HDD/SSD Hardware RAID Storage


USB 3.2 Gen 2 Type C, Hot-Swappable Drive 





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's built-in SATA 6G hardware RAID controller chipset and USB 3.2 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. (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 ST2 is equipped with four configuration modes to suit every need


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 different disk capacity volumes into one big volume

USB 3.2 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 3.2 transmission interface. 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


The new ST2-B31 support the USB Type-C interface, which is based on the USB 3.2 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 3.2 cable to install, any both sides can be inserted.

ST2 to support both of 3.5" HDD and 2.5" HDD & SSD products

To bundle with two new easy-to-use Trays, ST2 supports any kinds of 3.5" & 2.5" HDDs/SSDs.  And also, ST2's aluminum housing help protecting your data from its solid structure design and 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.

The solid aluminum chassis pluses one powerful low noise Fans


ST2-B31's solid chassis is made by a thickness aluminum-alloy plate.  And its aluminum housing and the 4 cm FANs (with safe FAN GUARDs) really help an efficient heat dissipation for your long time use.


The new ST2-B31 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. 

Just to use ST2-B31 for data backup

You can also easily extend your legacy device with Thunderbolt 3 (USB-C) interface, which connects to a iMac Pro device with Thunderbolt 3 (USB-C) interface. Your iMac Pro could connect to one ST2-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.

Big storage volume for your creative contents
ST2-B31 provide two HDDs storage system with JBOD storage, ST2-B31 is compatible to most of HDD product which are available in the market.  Under ST2 storage which its RAID 0 mode, you could get more storage capacity.  And its RAID 1 feature not only gives you a good data protection.

Help you to achieve various photos editing 

Since ST2-B31 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 right away.  You could then save tons of RAW images.  And of course, you could edit and process the images quickly once you set up your ST2-31 with RAID 0 feature.
