Would this work? Two Operating Systems, One MacBook Pro?

[Alexrkstr]

The situation
I have a MacBook Pro mid 2009 (5,5) Core 2 Duo, 2.53GHz, 4RAM, 5400rpm HDD and I bought the upgrade to PT11 from PT8LE.
I own the 003 mixer console, FireWire.
I know that 8LE works well with Snow Leopard.
PT11 works in some machines with Yosemite

Complication
My current laptop + Yosemite + 003 + PT11 doesn't seem to work.

Questions
Has anyone here done this, or would anyone have fact-based opinions about having two partitions on a hard drive and install:
1) Partition I: Snow Leopard with PT10, also a 32-bit app
2) Partition II: Yosemite with PT11 solely for mixing purposes
Or should I just forget about PT11 and roll everything back to Snow Leopard and install PT10? Other than an optimized performance (ironic I'm saying this now), is there a significant difference between PT10 and PT11? Are the interfaces the same? I can only identify the new click track and the performance enhancements to be the difference between 10 and 11.

How large is your drive? I had a 500GB on my MBPro and divided it into 3-partitions, which you can do at anytime. I had Mavericks, then installed Yosemite on a 2nd partition, and the 3rd was for DATA, i.e. non-system files and non-apps. You should easily be able to install your system and all necessary apps on 120GB or less.

With the above example, you would shrink your current partition to whatever makes sense, assuming you've got everything on a single one, then create a 2nd one of 100GB or so for Snow Kitty, or however you want to do it.

The great thing about this consideration is that I am looking at the OWC solid state drives, so I haven't bought any yet. I was thinking of going with the 120GB (60GB per OS) since I keep all files in external drives.

Not quite, I have Mountain Lion with PT10 and PT11 on my Core2Duo MacBook Pro, 8gb RAM, 750gb 7200rpm hard drive. I have Snow Leopard with PT8LE on an external USB 7200rpm 500gb drive and boot from that when I need to. I also replaced the internal DVD Superdrive with a second hard drive 1tb 7200rpm that I use to keep key sample libraries for plugins on.

I use a 500gb Lacie Rugged 7200rpm Firewire drive to record onto.

My 003 console is connected using a SonnetTech Firewire Expressport Card.

All working well, within the limits of the Core2Duo's capability and the outstanding issues with PT11.

PT11 is more efficient than PT10 resource wise, which is good for older computers, but the issues are still a problem. Generally not bad on audio only projects, but I wouldn't trust it on projects with much in the way of VI. Better to use Vienna as a host in that case, that seems more stable than VI directly in PT11.
