Optical bay SSD as startup disk?

So moving the optical drive from the laptop is no issue with future use of it as an external? It will function as if it was still internal? I recently got an adapter to install an SSD in place of it (I almost couldn't pass it up - it came with the adapter, SSD, and enclosure to move the optical drive to use externally). I've been wanting an SSD but they are costly when you go to a larger capacity, especially since you can only have one HD in a laptop. I want to keep my 750 GB internal HD, and I'm hoping this SSD mod will give me all the pleasure and speed of the SSD as the boot drive. Unless, since it is going into the old optical drive space there is a difference in how the drive is addressed/accessed; or will it just appear as another drive?

I had some time to think about this and as I aid on the other question, I've had fewer problems putting the new drive in the bay. But I'm wondering about the BUS speed of the optical drive bay vs the hard drive bay. You might want to do some testing to see if there is a loss in speed with the optical bay.

Mayer - Depending on which optical drive the given system had (PATA Vs SATA I/O'ed) moving the HD over to the optical carrier may make sense (putting the SSD on the systems HD's SATA I/O connector). This would be true for either iMac or MacBook Pro systems. If the carrier's I/O is PATA I would swap them to gain the speed of the SSD booting & running the OS from the systems SATA HD connector. If the carriers I/O is SATA there's little benefit in swapping.

Since you have your shipped internal drive still there, you have an option from System Preference>Startup Disk to chose your new SSD as Startup System Drive. You won't have noticeable speed loss if you fear. Your new drive will be recognized system drive since you have applied it as Startup Drive. Some Macs shipped with dual drives such as Mid 2011 iMacs shipped with both SSD and HD have clearly recognized SSD as built-in and HD as external drive that can be ejected if you wish to. There is no harm at all. My only concern is that please select your babied SSD as Startup System Drive. This way it is not ejectable.
