Note: Some hard drives have power-saving features on the disk itself and in very rare cases (about 0.002%) that power-saving feature may cause the USB host of MB174U3S-4SB to refresh the connections. This refresh can cause interruptions in data transfers and could potentially cause data corruption on the drives. We have carefully tested and reviewed this issue and we believe this problem is closely related to the power-saving feature of certain HDDs. If you experience a data corruption issue related to refreshing connections, please contact us for the solution.
We are proud to introduce the Black Vortex MB174U3S-4SB, the USB 3.0 and eSATA quad bay external enclosure with an eye catching design and removable drive feature. This unique HDD enclosure is designed for computer enthusiasts and gamers who need massive storage device without modifying their system or taking up additional system space. The MB174U3S-4SB accepts up to four 3.5” SATA 3 hard drives with blazing fast USB 3.0 and eSATA interface. The built-in 120mm cool blue LED fan with all around mesh design provides excellent cooling to the drive which can extend HDD lifespan. The easy access fan speed control and LED brightness control allow you to configure various setting that fits your need. Lastly, the EZ-Grip handles gives you the ability to replace drives in a matter of seconds. The Black Vortex MB174U3S-4SB is a must-have multi-bay enclosure that perfectly blends performance and aesthetics.
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.
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.

Note: the USB host will refresh while swapping drive via USB. The remaining drive(s) will power cycle during this process)
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.

Expand your NAS or Home Server Storage Capacity up to 32TB with Black Vortex MB174U3S-4SB
The average home is becoming a digital playground for all types of media; therefore more and more home owners have begun adding Network Attached Storage to their home setup. With Network Attached Storage (NAS) or a home server you can easily share your documents, photos, videos and all types of media with multiple systems including game consoles, desktop computers, MacBook, media box, mobile devices and more. What happen if you run out of the space? The Black Vortex MB174U3S-4SB USB 3.0 & eSATA enclosure is your answer. It takes 4 x 3.5” HDD and supports the newest 8TB drive on the market which gives you up to 32TB in total capacity (hard drives are not included). This enclosure has an extra large 120mm cooling fan that keeps drives cool 24/7 while being whisper quiet, which is ideal for NAS or Home Server systems and best of all, it includes individual power buttons for each bay so you can power off the drives separately to save power, extend the drive life span and prevent virus attack for offline backups. You can also attach the MB174U3S-4SB to your wireless router that has a USB 3.0 / eSATA port and supports data share function.

Your NAS, Wireless Router and Home Server need to support USB 3.0 and eSATA port-multiplier in order to see four drives at the same time.
Ideal HDD Cooling Cage Solution for 24/7 Downtime-intolerant File Server or Data Storage with ICY DOCK Black Vortex Series
Hard drives are like the brains of the computer by keeping track of all the data held and recalling all that data within few clicks. However, like human brains, an overheated hard drive always pose problems and without proper cooling, the drive can degrade over time, create errors in your data and eventually prematurely fail with all the data you put on it*. However, in the MB074SP-1B and MB074SP-B 3.5" drive cage, overheating is never an issue. A constant air flow is provided by its front 120mm LED fan, allowing the heat to dissipate away from the drives easily. Also, the removable, cleanable, fan filter in the front of the unit prevents dust buildup and removes the possibility of overheated hard drives caused by insulating dust. All of this is in a solid metal mesh construction design that helps with conducting and spreading out the heat from the drives while keeping the drives secure. Don’t let heat kill your hard drives; put them in the Black Vortex to keep them nice and cool.
