Why is there a 750GB limitation with an optical drive bay HDD?
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?
Is this a good question?

You could install your 500GB SSD in the optical bay and the 1TB HDD in the original HDD bay..

You could… but that would be counter-productive :( The optical bay bus runs slower than the other one on the machines. They were the same on later models.
