All Macbooks use 9.5mm Optical Drive Caddy, also, If you’re wondering as well, the Optical Drive runs at SATA II speeds just like with the main hard drive area, so if you’re using a SSD, then it’s going to run at a slightly slower speed.
Hi, I know I’m 3 years late, but you need to go into Disk Utility in Mac, and then format the drive that you putted in where the Optical Drive is, and then it should detect it, and therefore, you can use it for more storage.
NOTE: when you’re installing a SSD in the Optical Drive Caddy, you’re only going to get SATA II Speeds, I would strongly recommend ditching RAID 0 configuration since the Optical Drive Caddy does not support SATA III speeds.
No, even though it says that the Optical Drive is SATA III Speed, when you put in a DVD Drive Caddy with a Hard Drive/SSD, it will only work with SATA II Speeds or lower, I would recommend ditching the RAID 0 Idea for the Optical Drive Caddy.
