Do you have some 2.5” SATA drives or a SAS drive you want to be able to hot swap? Then you should take a look at the MB991IK-B Hard Drive Enclosure from Icy Dock.

Here is how Icy Dock describe the MB991IK-B:

Introducing the Icy Dock MB991IK-B 2.5″ SATA/SAS Mobile Rack for use in 3.5″ device bays. This product is constructed of heavy duty SECC metal to hold up in the toughest of conditions. It includes ventilation slots on the front, back, top and bottom for maximum airflow to keep both SATA and SAS drives running cool, and an LED is placed on the front of the device to give the user drive status at all times.

The MB991IK-B also utilizes our brand new EZ Slide Mini Trays, making drive interchangeability and maintenance completely hassle free. The trays are built using SECC so that they are durable for many lifetimes, but will not weigh you down when transporting your data from system to system. The trays are also designed to accommodate 9.5mm, 12.5mm, and 15mm drives giving you the ultimate universal 2.5″ hot swap bay.

Both SAS and SATA drives are compatible, allowing users to use low power 5400 rpm drives, or 15000 rpm powerhouses, making this product valuable to end users and enterprise server deployment. Similarly, the MB991IK-B supports the new SATA 6Gbps interface for ultra high bandwidth. For enterprise users, a key lock is included to keep your data safe and secure inside the enclosure even if the entire system has been stolen.

The box is very small, in fact only slightly bigger that the drive enclosure itself. It contains the enclosure, a set of keys to lock the drive in place, some screws and a small user manual.




As you would expect from a drive enclosure, it is very simple to use and fit. The rear of the enclosure has a power connector, a SATA port and a SAS port.





Adding a drive to the enclosure is very simple. You just open the front of the enclosure and slide the drive bay out. You then place either a 2.5” SATA drive or a SAS drive into the drive by and fix it in place with four screws.

You then slide the bay back in and the front closes up with a click. You can then choose to either lock the drive in place or not bother. For ease of showing this, the pictures below show the enclosure outside of a desktop computer, although you would do this with the enclosure already fitted in the desktop.




There isn’t really much else to say on using the enclosure. It is very easy to fit, easy to use, and works very well. Simple!

This sounds like the previous Icy Dock hard drive enclosure I reviewed, and that is because Icy Dock make all their enclosures to be simple and easy to use.

I had no problems at all and found it to be very simple. Although I would say that sliding a SAS drive in and out of the drive bay was a little tight, so take your time and don’t put too much pressure on it.

Overall I can highly recommend this enclosure as it works and does what it says on the tin. Yet another product from Icy Dock worth having.

The MB991IK-B Hard Drive enclosure retails for less than $35, so it certainly won’t break the bank and is a very useful edition to your system, especially if you have some “spare” 2.5” or SAS drives laying about that you want to swap in and out of your computer.

And the beauty of this enclosure is that it will work with much smaller computer cases as it is designed to fit in a 3.5” drive bay.
