I recently bought a caddy off of eBay that will allow me to install my stock Macbook Pro 2011 500Gb Toshiba HDD in the optical bay with a Vertex 3 SSD in the traditional hard drive bay. I received the caddy and was going to install it when I noticed a sticker on it that said Serial ATA 1.5Gb/s. I know that the 2011 MBP has SATA 3 in the optical bay, so I'm wondering if the caddy will limit my hard drive to only 1.5Gb/s. Thanks for any help you can give!
