I have a Dell E6400 and am running out of memory on my hard drive. It should be quick and easy to use a caddy with a SATA 2.5 to replace my optic drive. My only concern is that it seems the SATA drives have variable heights and there are some comments online about the taller drives not fitting certain applications. Has anyone used the optic drive caddy and perhaps would know if size would be an issue? I want to go with a 2TB drive which limits my choices. I'm accumulating about 100-150GB of data from work alone per year so I want good capacity.
