Creating a dual boot MacBook Pro with two drives

I haven't set up my macbook pro with two drives yet as the gear is on its way.

Here's my future setup:

1.0TB Seagate SSHD in main bay

750GB HGST Travelstar™ 7K750 in optibay

Seagate will be main OS drive

HGST will be partitioned for windows and extra storage for both systems.

The question is, what is the best way to start this project?

I was thinking I'd install HGST into main bay and boot up the mac from the original drive externally, partition the HGST, install windows, clone original drive onto Seagate, put everthing in order and viola! Is this good? Is there a better way? What do I need to know before proceeding? Thank you.

How about focusing on your primary drive first. Using your external case to hold your new drive prep it and clone your current drive over. Make sure your new drive is able to boot up externally, then swap it out give your system a quick test then work on the optical drive swap-out.

Make sure your new HGST drive can run at SATA II (3.0 Gb/s). Many of the newer MacBook Pro's optical drive port run slow and will not work reliably at SATA III (6.0 Gb/s). Review the note in Red at the bottom of the OWC Data Doubler. I should point out it makes no difference who's carrier you use the issue is within the MacBook's controller chip.

Ok that seems more appropriate to do first. I've checked so many times on multiple websites to make sure that the second drive I get was 3G SATA. And it is. (Interface: SATA 3.0Gb/s NCQ) this is from the drive's page at OWC. The OWC Data Doubler you linked isn't compatible with MacbookPro6,2 while the one I ordered claims that it is. I panicked for a moment and went to check for the millionth time. However, is this procedure good? Is it reliable? I'm a bit scared. I heard that BootCamp won't install windows on a secondary drive (optibay drive) because it treats it as an external drive.

Who's carrier are you using? It makes no difference who's carrier you get the problem is within the main logic boards SATA controller chip. The OWC or the IFIXIT units will also work. The carrier is only a signal pass-through it has no logic.

You can't install BootCamp on any second drive. Even if you setup the drive as your primary and installed OS-X and BootCamp and then switched it over as the second drive BootCamp won't run as the OS on the primary drive won't have the needed drivers or volume/directory pathing. I should also point out you would loose the primary drives (SSHD) caching. Basically you should install BootCamp on the primary drive and install Windows and your Windows apps on it as well. Then, put your data onto a FAT32 or NTFS partition on the secondary drive to hold your windows data files.

I will be using OWC Data Doubler.

Ok, is it possible to "only" install windows OS on the primary drive and select the path for the secondary drive to be set as default for the system files and other stuff? If yes, how? Thank you

I think your over thinking this... The Windows apps should stay on the SSHD for performance. The data files you create or have (which can be bulky) can sit on the other drive. This is where you'll need to create a second partition which is Windows based. We do the same thing (we have external disks) which hold the customers files (CAD & AVI files).

Since you're going to be installing an SSD and moving the platter drive to the optical bay, another option that might work is to configure them as a Fusion Drive. This drive (an option in iMacs and Mac minis) joins an SSD and a platter drive together as a single Finder volume, and stores the files you access most frequently (OS, applications, preferences etc.) on the SSD and puts the less-often used stuff on the slower platter drive.

It's not super-easy to configure a Fusion Drive on an unsupported system, but OWC has a fairly detailed explanation of the process. Their description is based on Mountain Lion/10.8.3, but the same methods can be used with later operating systems, since most of the key steps are done with Terminal.

Once the Fusion volume is readable in the Finder, Boot Camp Assistant should be able to create the Windows partition. Since the boot blocks for the one Finder volume will be on the SSD, BCA shouldn't complain; otherwise you wouldn't be able to run it on an iMac/mini with a factory-configured Fusion Drive either.

He's setting up two HD's. One is a SSHD (hybrid drive). While I agree doing a fusion drive is a good way to go in a iMac. In MacBook Pro's I don't like them as the optical drives SATA port messes things up. Between the slower SATA speed and the lack of HD crash guard limits its use. Which is why we do SSHD's now in the newer MacBook Pro's.

This Fusion drive setup is almost like a RAID which I have researched and found that its not the best choice for me for many reasons. Thanks for suggesting though. And I'm a (she).
