Multiple Interfaces with Great Capacity

As storage space remains an integral part of many applications, the MB174U3S-4SB aims to fill the void which the storage market has neglected. With support of up to 4 drives, the Black Vortex can provide ample storage space for all your data needs without occupying space within your system.

Icy Dock Black Vortex Drive enclosure

Boasting SuperSpeed USB 3.0, the Black Vortex MB174U3S-4SB can quickly transfer files between your computer and your external drives, or transfer the file in between the drives in the blink of an eye. MB174U3S-4SB also featuring UASP support, which delivers higher transfer speeds to supporting devices. With backwards compatible USB 2.0 support, you can connect it to many supporting devices that support external storage devices through USB 2.0 such as wireless routers, gaming consoles, Nas storage, and smart TVs that have USB interface.

Our new external enclosure also supports eSATA port-multiplier interface for those that don’t have USB 3.0 interface. (Requires eSATA port multiplier support from host end in order to detect all drives).

EZ-Grip Handles

Drive installation has never been easier with the EZ-Grip handles. Installing EZ-Grip to your hard drive only requires two screws. You can easily slide your drive into the Cage and lock the switch. Once your drives are locked in place, they’re not going anywhere. The EZ-Grip handles are compatible with our lineup of portable docks such as the MB881 and MB981 HDD docking stations. You can quickly remove your drive from the Black Vortex, and insert them into our docking stations without removing the EZ-Grip handles. This is extremely useful when transferring data in between systems. We've included two bonus EZ-Grip handles so you swap between a total of 6 drives. The EZ-Grip handles are compatible with our 2.5” to 3.5’ HDD/SSD Ezconvert series: EZ-Convert MB382, MB482, MB882 & MB982 series, allowing you use your 2.5” HDD/SSD with the Black Vortex hassle-free.

Efficient Cooling

The Black Vortex MB174U3S-4SB gets its name from the whopping 120mm fan integrated in the unit, which allows it to efficiently cool your drives and increase HDD lifespan. The included 120mm fan effectively pulls cool air into the enclosure resulting in a lower overall temperature for your drives which prevents performance decrease from overheating disks. We’ve included an adjustable 3 settings fan switch (high, low, and off) to allow you more control over airflow, temperatures, and noise levels. The 120mm fan also features an adjustable built-in LED lighting that brilliantly Illuminates and provides an ambient blue color. It’s a surefire way to grab the attention of everyone in the room.

Easy Maintenance and Controls

Controlling the enclosure is simple and can be done by accessing the front of the enclosure. With brightness controls, the 3 different settings (high, low, and off) allows you to dim and brighten the LED fan with a simple touch. Fan controls allow you to adjust the airflow from high, low, and off, and the 120mm cooling fan can be easily replaced to an aftermarket 120mm fan with 3 pin connector.

Clean up is a breeze with the included removable dust filter that can easily be detached and rinsed within a matter of seconds. We’ve made the protruding handles removable if you’re looking for a more minimalist design and we’ve designed this enclosure to be tough yet attractive.

  • About BITS  
    Welcome to the BITS Online Store

    BITS was incorporated in March 1993 and started life catering to the needs of Australia's Professional Graphics Bureaus and In-House Design Studios. We quickly became experts with digital film recorders and machines for producing overhead transparencies for meetings and presentations. We ventured into large format printers and associated image processing hardware and software for CAD and presentation graphics. Later on we were building our own branded computers and servers and importing drive cases for the manufacture of external hard drives. BITS was one of the first companies to go online with e-commerce and to this day still offer internet web hosting services which we started back in the early 1990's. BITS now offers hardware and software products to a select group of loyal customers and happy to provide good old fashioned service to new ones.
