Yep. That is correct. Makes for minimal cabling at least. I've used a bunch of different sata cages 1-in-1s, 3-in-2s, 4-in-3s, and 5-in-3s, form a bunch of different manufactures in other non unRaid builds. From IStar, ABS, Kingwin, Icydock and supermicro. These by far are my favorite so far. They are extremely light being all aluminum. The first one i got I was a little bit worried cause the box was so light I figured that they had sent me nothing or the wrong thing. These were a bit hard to get. IStar announced them on 1/5/11. I'd been looking for them for a few months with no luck. I had been doing part number searches on google daily since I found them in January and a few weeks ago they showed up on newegg.ca. So i went to the US newegg and they only showed up if you did a part number search. Due to low inventory, it took me three different orders to get all three cages. I believe I actually have the cage that newegg used in the photos. It was the second one i got. The first and third ones I got were shrink wrapped. The second was not.
