Where is the perfect place for an Operating System-SSD?

My Question is stated above and refers specifically to the MacBook Pro 15 inch mid-2010 model.

My plan is to have the SSD Mac OS X installed on it, and a partition with a Windows-OS.

The second thing is that I want to keep my normal HDD for data-saving purposes.

I have been on several websites and Google search results but I still do not have a clue, where inside this MacBook Pro model the most convenient place for a SSD is.

Somewhere I heard, having the Operation System-Disk, in my case the SSD, in an optical bay, will cause the Mac to crash, somewhere else I heard the SATA Connector for the SuperDrive is not that fast for having a SSD connected with it.

And again I also heard that moving the standard HDD to the optical bay will cause strange sounds coming out inside the Macbook or that it depends on the MacBook model.

Please, if somebody already has experiences on this and hopefully with the same device, I would be very glad if someone helped me.

Not sure I follow you here. You implied you were removing the optical drive so the HD (or SSD) would replace it using the special Optical bay SATA enclosure iFixIt offers. Is that not correct?

To rephrase what you'll have here is the current HD will be replaced by the new SSD, you will then take the optical drive out and put your current HD in a special carrier and put it in it's place.

The Mac OS-X will need to be copied over to the SSD before hand using Universal drive adapter or better yet a firewire external case.

As to to Windows I don't think you want to run bootcamp with Windows from the SSD. It would be better to use a VM like VMware Fusion to run Windows. You can't run it via CD/DVD as you won't have an optical drive in the system, though you could mount it in an external case and use it that way (5.25" enclosure). So later on you can decide to install it.

Ah sorry, yes I want to swap the Optical Drive with the HDD or SSD and that is my problem, I would rather let the HDD in its place and use the SSD in the optical bay but I heard there are some issues on this if the SSD holds the Operation System. Also I heard in some Macbooks the full speed of the SSD can not be used that way. If you have any information on that, please let me know.

With my comment I meant if I replace the HDD with the SSD then I could install Mac OS X first on it per the Install DVD. After that I had planned to install Windows via Bootcamp. After this is done can't I just put the SSD into the optical bay and put the HDD in its original place? If there are some issues and problems please let me know.

Also I wouldn't want to run Windows on VMWare because I need it to be native. But I am not up to date on this issue if VMWare has been improved or not.

Additionally: The Macbook I plan to do this on is new, I am getting it from my brother so there is or will be no data on the HDD.


OK - You really want the SSD to be connected to the current HD SATA connector. There is a lot of reasons for this speed & compatibility being the two major ones. - To install your OS-X on your SSD you'll need an external connection via the Universal drive adapter I have linked for you. You do this before opening the system. - Windows is an issue via bootcamp with SSD's. You need to go with a VM, VMware is very good I use it with out any problems.


Thank you very much! Good to know about the speed and compatibility. I did not know if my Macbook model was capable to handle this or not.

And thanks for the Universal drive adapter I think I will need it when I have got the SSD!


First, you need to swap your drives around putting the SSD where the HD is currently. Then you can set it up as the boot disk for OS-X. Different models have different issues on why you want to do this. In your case you need to upgrade the EFI (if its not running the latest) so the HD SATA connector can run at the higher speed.

Windows adds a wrinkle here. How are you planning to run it? Using Bootcamp or a VM?


I plan to first replace the HDD with the SSD, then secondly I want to install Windows per SuperDrive. After that I can still decide where to put the different drives, can't I?
