Introducing the FatCage MB155SP-B, a 5-in-3 SATA 6Gbps hot swappable internal RAID backplane cage. This is the lite version of the MB45X series by removing the monitoring features, increasing the cooling performance, and reducing the overall cost, while keeping the same 3 year warranty and the core tray system for hot swapping and maintenance are kept for the best reliability in the market.
Maximum Space Saving & Reliable Build
The MB155SP-B built to be a lighter module, while more importantly maintaining the same level of quality, build, and service you’d expect from an Icy Dock product. While the design has gone through some changes, the space saving design is still established. The backplane module allows up to a massive 5 x 3.5” SATA III hard drives, while only consuming three 5.25” bays.
The FatCage has also been redesigned for the type of power connector accepted. 15 pin SATA power is used to provide better accessibility for most modern host systems. They are also compatible with cables with metal latches to improve security when installed into a system.
Along with being a lighter package, the cooling has been redesigned to provide the utmost airflow to your hard drives. The FatCage uses a full metal body that allows for the effective heat dissipation possible in various types of applications. Meanwhile, our enhanced direct air flow design allows the included a large 92mm cooling fan to raise its efficiency to cool down your hard drives, by closing and rerouting most vents to route incoming air directly to the cooling fan. There are dual exhaust vents on the top and bottom to additionally help keep drives temperatures while improve airflow.
In addition, the backplane logic PCB has larger cut outs in key locations to allow more air to flow into and exit the MB155SP-B, making it an ideal system to store and cool your hard drives.
Modularized Cooling System
The included 92mm cooling fan is fully modularized for the most hassle free experience of replacing and maintaining and is compatible with most aftermarket cooling fans of the same size. To expand the range of compatible fans, both 2 and 3 pin fan power ports are available and are conveniently located for great accessibility. This provides the user the most flexible options available and freedom desired.
The FatCage MB155SP-B features a 3 mode fan speed jumper which can be changed at will to control the fan speed easily. The 3 modes include: High, Low and Off with respective speeds of 100%, 60% and 0% relative to maximum output. The settings can be simply changed by removing the jumper and relocating into the desired setting.
Reliable Hot Swap System
The MB155SP-B has kept the same interchangeable EZ-Tray used in MB45X, MB876, MB559, and MB561 series. This allows you to continue to use the same trays from these series, or our compatible external 3.5” models without any issues regarding switching to new designs. The EZ-Tray accepts most 3.5” SATA hard drives and is very easy to install / remove to the device in two steps – press the release button and pull / push the lever. The built in rail system acts as the mechanism to ensure a fully secured connection every time. This allows for easy replacement in case of RAID failure or transporting of data.

Expand Your Data Storage Capability with ICY DOCK Fatcage and Datacage
Upgrading a system with SSDs has never been easier! ICY DOCK’s 3.5” mobile racks (DataCage and FatCage series) now come with our new MB453TRAY-2B which is compatible with both 3.5” and 2.5” HDD/SSD. This means with the MB455SPF-B/MB155SPF-B, a user can use 2x SSD in RAID 0 for increased OS speed + 3x 8TB HDD for large data storage. Or using an MB453SPF-B/MB153SPF-B with 2x 8TB HDD in RAID 1 for redundancy + 1x SSD for OS speed upgrade. It is a cost effective way to speed up your system by upgrading to SSD while keeping your old drive for storage purposes. In addition, if you already have an older version DataCage or FatCage product, you can easily upgrade your system by obtaining the MB453TRAY-2B.

"The Icy Dock FatCage works and performs as advertised. If you are using higher performing drives that generate more heat though, this is the model to get since it does get a little better cooling"
