ICY DOCK 4 Bay USB 3.0/ eSATA External HDD Enclosure with 120mm Cooling Fan - Black Vortex MB174U3S-4SB

  • 3.5"
  • USB 3.0 or eSATA
  • 4 x 10TB
  • Metal body with partial plastic

The ICY DOCK MB174U3S-4SB is a stylish, easy-to-use four-bay 3.5" HDD enclosure, great for power users and geeks requiring massive storage for their endless music, videos, photos and games. It connects to your computer via 5Gbps USB 3.0, or 3Gbps eSATA, and is actively cooled by a 120mm LED fan. The EZ-Grip handles gives you the ability to replace drives in a matter of seconds. Plus, this docking station is toughly built with metal frame, assuring you unrivalled durability you and you drives can rely on.

Note: WD Green and WD Red hard drives have a feature called Intellipark. This feature makes the drives automatically park themselves after being idle for 8 seconds. There is a small chance that certain drives may appear offline to the USB host of the MB174U3S-4SB and can cause the USB host to refresh. This could cause the remaining drive(s) to power cycle, interrupting any data transfer and potentially causing data corruption on the drives. We recommend WD Green and WD Red drive users to disable the Intellipark feature to prevent this issue.

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.

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. An adjustable 3 settings fan switch (high, low, and off) allows 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.

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.
