Late 2011 13" MBP with SSD in Optical Bay

put your SSD into the main bay so you get SATAIII speed.

Is the 1TB HDD 3.5in or 2.5in?
Optibay only supports laptop sized HDD/SSD (2.5in) and not desktop size HDDs(3.5in).

EDIT:

I just googled it and yes, it is a 2.5in so it fits.

OP is asking about the height of the drive being an obstacle though, which will depend on the thickness of the specific "cradle" used to mount the 12.5 tall WD HDD he mentioned after moving it into the optical bay.

As far as I know the late 2011 MBP get Sata III in the Optical Bay as well though so there doesn't appear to be an obstacle to leaving the WD HDD in place in the HD spot and sticking the SSD in the location of the removed optical drive.

Please correct if wrong.

I'm guessing it won't fit since it's 12.5mm. It most likely needs to be 9.5mm to fit in the caddy.
