Product Overview

Budget Friendly RAID Alternative

Introducing the FatCage MB153SP-B, a 3-in-2 SATA internal RAID backplane for 3.5” SATA hard drives. This is a lite version of the MB45X series by removing the monitoring features 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.

Slimmed Down Design

The MB153SP-B has been redesigned to be a lighter module, while 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 3 x 3.5” SATA III hard drives, while only consuming two external 5.25” bays. The module has also been redesigned for the type of power connector accepted. 15 pin SATA power is used to provide better accessibility for various host systems.

Efficient Cooling

Along with being a lighter package, the cooling has been improved to provide better air flow to your hard drives. The MB153SP-B uses a full metal body that allows for the best heat dissipation possible in various types of applications. In addition, our enhanced direct air flow design allows the included cooling fan to raise its efficiency to cool down your hard drives, by closing and rerouting any side vents to route incoming air directly to the cooling fan, as well as sealing any vents around the fan for better cooling efficiency. In addition, the backplane logic PCB has larger vents in key areas to allow more air to flow into and exit the MB153SP-B, making it an ideal system to store and cool your hard drives. The included 80mm cooling fan also can be easily replaced and maintained, as the unit it can be fully removed and replaced with 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 can be easily accessed.

No Hassle Maintenance

The MB153SP-B has kept the same interchangeable EZ-Tray used in MB45X, 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. This allows for easy replacement in case of RAID failure or transporting of data.

ICY DOCK FatCage MB153SP-B, 3.5" SATA/SAS RAID Backplane Cage External 5.25" Bay, HotSwap, 80mm Fan is rated 2.8 out of 5 by 4.
Rated 1 out of 5 by from Ruins perfectly good hard disk 1 year ago I put a drive in this caddy. Today I removed the drive so that I could plug it into another PC. The sata connector on the back of the hard disk was left behind, broken off and stuck in the caddy. One ruined hard disk. One unusable bay in the caddy. I don't think it's the hard drive at fault, it's a high end Seagate drive. Avoid this product.

Rated 5 out of 5 by from quick way to use a hot-swap raid array Over time this is the 5th of these drive bays I have fitted to various servers to enable hot-swapping, the fact 3 drives fit into a 2 drive space has advantages. Never had one of these bays fail, the more recent ones use sata power sockets, the older ones used to use Pata/Molex. You do need to mount the individual drives in a caddy, but I have spares of these already.

Rated 3 out of 5 by from Overpriced, but no other choice I would not recommend this product, as I wouldn't have bought it myself if I had any other choice. I was looking for a simple 3-in-2 enclosure, to fit 3x3.5'' HDDs in the 2x5.25'' optical bay of a Fractal Design Define R5. I did not require cooling or hot-swappable function or anything like that. However, there is no product out there that fits the above description, so I settled paying £70 for this thing. To be fair, it does the job. However, there are 2 things you have to be careful about. a) It fits very tightly, so things may go wrong with some cases. However, it fits in the Fractal Design Define R5, that is for sure. b) The fan is very small and thus very noisy at full speed. So if you want to avoid ear damage (!) connect it to an adjustable fan controller, so that you can turn it down a bit.

Rated 2 out of 5 by from Icy Dock MB153SP-B "FatCage" 3 in 2 SATA Internal Backplane Module The drive cage that you insert with the locking leaver has a weak spring to press and open it has a problem and then it solved itself. But the press down button to release the locking leaver is a bit small and could be an asset. The hard 4tb Drive/s do not slide in and out smooth an scratch the top of the 4tb Drive/s

Does this fin into Fractal Define R5?

I need something just like that for my PC, but I was wondering if it going to fit in my case, in the place of the 2x5.25'' optical bay. My case is as mentioned the Fractal Define R5.
Asked by: korkinof
I don't know your specific case but I have never had a problem fitting the 3 bay unit into a 2 x 5.25". I did have problems fitting a 4 bay into 3 x 5.25" where I had to bend some locating lugs out of the way.
