Chosen Solution
I would like to install a 1TB 2.5 HDD in the optical bay slot (Macbook Pro Unibody mid 2012). I currently have a 500GB HDD in the optical bay and a 500GB SSD in the original hard drive bay. I am curious to the 750 GB limitation that is noted in the description. Product Code: IF107-080-3 Update The specs: 2012 macbook pro 10.10.3 OS X 4 GB Ram 2.53Ghz Quad I7 500 SSD has 1 OS partition 500 HDD 5400 RPM has 1 data partition 1 TB HDD 7200RPM has multiple partitions Initial config: 500 SSD in HDD bay 500 HDD (original drive) in Optical bay Benchmark SSD:Write 1024KB (451.306 MB/sec) Max Results: 500 SSD boots properly 500 HDD reads and writes properly New Configuration 1: 500 SSD in Optical Bay 1TB HDD in HDD bay Results: the 1 TB drive worked fine. The 500 SDD (with the primary OS partition) had difficulty booting. After several attempts, the SDD booted to the OS. I attempted to run a benchmark test. The results were sporadic and had several force restarts. Benchmark SSD:Not stable enough to officially record New Configuration 2: 500 SSD in HDD bay 1 TB HDD in Optical bay Results: The SSD worked fine. After booting to OS (using SSD), the 1 TB drive requested that I Initialize the drive. (Disk utility shows the individual partitions (disk1s1 etc) without any names) Occasionally, a single partition will mount and it is not always the same partition that mounts from that drive. If a 1TB drive works, maybe it needs to be <7200 Rpm?
That is very curious. Other opt-bat devices do not seem to have this limitation: http://www.mcetech.com/optibay/
