My aging MacPro is well, aged :) and dying. I don't want to buy another but rather use my new Macbook Pro. The only problem is a massive lack of storage. I'm used to 6x drives, all SSD.

Right now the MBP has a 128GB SSD which is fine for it. I want to run my Win8 VMs on this mac and was thinking of keeping them on a 64GB MicroSD (MicroSDXC Class 10 UHS-1 30MB/s Memory Card).

Since the VM isn't on all the time it seems like the SD might make it ... So my questions are really, can a SD card even handle the load of running an OS? what others problems might arise doing this?

Thanks!

Turns out this isn't possible. It works sure but the SD cards are just too slow to run a VM and I was using something super lean and it still struggled. I used the fastest MicroSDXC/HC card at 64GB from SanDisk. My only solution was to upgrade the primary SSD to something bigger and that worked out well.

I was thinking of doing this for my Macbook AIR 128GB SSD. The problem is that you can't upgrade the harddrive. My Windows XP VM is 30GB and I was using VMWare 3 (I will have to upgrade it to version 5 for OSX Mountain Lion). Was also concerned if the SD card would sit securely or pop out if a coffee mug bumped into it. I have yet to use an SD card so it might not be a problem. I suppose maybe I could move other things to the SD card though and keep my vm on the main drive? –  1.21 gigawatts Mar 14 '13 at 6:01
    
yeah but the SD cards aren't fast enough - no real solution, hack the machine for a bigger SSD which are cheaper now or upgrade the mac :) –  typemismatch Mar 14 '13 at 21:00
