The Hardware RAID Storage with Touch Power Button


ST4-TB3+ is a hardware RAID storage with dual RAID combinations. With the hardware RAID chip inside, it can support both Windows and macOS, user do not need to worry about the cross-platform application. It is the economical and efficient RAID storage system.



Why Touch Power Button


ST4-TB3+ has the touch power button design on the front panel. It is more user friendly for the user just need to turn on the power switch on the rear panel, and can easily touch on/off the power of ST4-TB3+.


It also has the special design for the power-off mode to avoid the users accidentally touch the power and the device shut down immediately. All features make ST4-TB3+ is not only a more safety product but also has the elegant outlook.

The ST4-TB3+ is equipped with Four RAID configuration modes, can set up Two RAID groups independently 


The ST4-TB3+ has Four RAID configuration modes: RAID 1 (Safe Mode), RAID 0 (Speed Mode), JBOD (Four Independent Volumes) and BIG Mode. RAID 0/1/BIG can be set up as two independent RAID groups based on users' application.


RAID 1 function: provides fully automatic backup that ensures data security.


RAID 0 function: increases storage speed and performance.


JBOD function provides four independent disk data access convenience.


BIG function: provides two independent disk capacity added total.

Thunderbolt 3 (USB-C) brings you the 40Gbps extreme high data transfer bandwidth

ST4-TB3+ has Dual Thunderbolt™ 3 (TB3) interface for an extreme high data transfer bandwidth up to 40Gb/s. It is Two times faster than Thunderbolt™ 2. Users could definitely use it to playthe 4K high-resolution films with no any lagging hassle. Thunderbolt™ 3 interface not only brings you the high data transfer rate advantage, it also let you daisy chain maximum up to another 5 more Thunderbolt™  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. 

Removable & Hot-swappable Disk Tray design, it support 3.5" and 2.5" SATA disk (HDD or SSD) 


ST4-TB3+ is bundle with four easy-to-use disk trays and support 3.5" & 2.5" SATA disk (HDD/SSD). The aluminum housing help protecting your data from its solid structure design and the excellent heat dissipation.


The easy-to-use disk tray is dimensional compliant to all our STARDOM products, you could easily transfer your data among different STARDOM devices. With the key lock design, it could provide a double protection for your data from any improper disk tray extracting.


Rugged Aluminum Chassis Design


ST4-TB3+'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.

Manual fan speed adjustment


The brand new ST4-TB3+ has the manual fan speed switch that on the back panel to adjust the high and low speed, allowing your device to have the heat dissipation quickly without affecting transmission performance.

ST4-TB3+ is design with stylish and durable

Thunderbolt™ 3 can provide more applications



Our Thunderbolt™ 3 storage device can transmit images, data and power supply at the same time with only one cable. It is the most advanced and versatile interface.


ST4-TB3+ provides a mini DisplayPort that allows users to connect display screens, compatible with existing DisplayPort devices, and can connect DVI, HDMI and VGA screens through an adapter cable.

With different applications >> Configure two different RAID groups


‧ Both safety and speed => RAID 1 + RAID 0


‧ Both security and capacity => RAID 1 + BIG


‧ More secure => 2 x RAID 1 + Software RAID 0 (RAID 10)


‧ Both capacity and speed => JBOD + Software RAID 0


Full data transfer bandwidth with Software RAID 0 mode

With the ST4-TB3+ in JBOD mode, you can get the full data transfer bandwidth of the ST4-TB3+ up to 1500MB/s by configuring it with software in RAID 0 storage mode, allowing you to quickly browse the large video database in the internal storage and instantly access any photo in the database.

A single hard drive is fast and portable, data can be plug and play


The unique JBOD function of ST4-TB3+ allows users to install 2.5" or 3.5" HDDs / SSDs, and supports plug and play features without complicated settings, and immediately expand the large-capacity hard drives you need. In addition, you can also take out a single hard drive and install the hard drive to read data in other operations. This allows you to move your important information quickly and safely.
