Overall the MB491SKL-B is pretty much the same thing as the MB492SKL-B, except with one large door instead of two smaller doors since it holds one drive instead of two. We will take a closer look at the device in order to cover what it has to offer and how it is a bit different than the 2-drive version.

The MB491SKL-B is also sold in a rather generic looking brown cardboard box with all black graphics and text. The product is well detailed on the packaging, so you would definitely know what you are getting, even without actually seeing the device itself. Inside the box you will find the MB491SKL-B, the user manual, screws, drive bay keys, and another set of drive ID plugs. These plugs didn't make sense to me with two drives, but make even less sense to me when there is just one drive - unless they are expecting you to get additional drive trays to be swapping in and out of the same housing.
