Are you sure? Because I already have a 2.5" SSD connected to my desktop, and I just used a normal SATA cable. I didn't anything like this.
Edit: You know, when I look at the picture of the one on DX and the one on Startech, the combined connector is a lot smaller on the startech one. I think DivineEvil is right, and that this is not a Slimline Sata adapter.
Does anyone know if DX has an adapter like this?
Or for a few $ more you can get this

That's what I have, should fit perfectly in my umbp 17 (early 2009). I'll install tomorrow.
