[OS X] Fusion Drived My 2011 17" MBP

Up until a few days ago I had installed a 256gb ssd in the main drive bay and used a OWC drive mount in the cd bay for a 1tb hard drive. Once it was discovered that creating a LVM Volume using both disks would enable fusion drive I jumped at the chance.

NOTE: If you have a setup like mine, if you can at all manage it, make sure your user account is not on the HDD. I had moved it onto the HDD to keep the media on the slow disk. Time Machine will want to see 2 drives to do a proper restore. What I had to do create that account again and do a restore of the directories and not a time machine restore. Annoying.

Performance is excellent, after a few reboots they were instant again just like when I had the SSD as the boot drive and the apps I use the most pop up instantly. I am quite happy with the setup and now that TM has backed everything up, restores work like they should so when it comes time to add a larger HDD down the road the restore should work fine. i Hope lol.

I did it to my MacBook Pro 15" awhile ago:
»Fusion Drive

I reformatted to 2 physical volumes a few weeks ago. The speeds were slightly slower, and I couldn't take the sound of the HD spinning up all the time with no way to spin it down.

Huh, I'm trying it on my Mini and so far it doesn't seem any slower than straight SSD. As it fills things will likely change.

The only thing I'm seeing is glacial boot times, but once booted, apps open instantly as if they've been moved to the SSD. My VM is also obviously running off SSD.

It's a 7200RPM drive. In a quiet room with no other moving parts, it's the only thing I can hear. Not to mention watching my battery life drain because of it.

Ditto.
Very annoying.

How bad a battery hit did the Fusion Drive install cost you, Td?

It wasn't the Fusion drive specifically. If I didn't manually manage when my HD spins down, it'd be just as bad with a regular two disk setup. In regular mode, I can unmount/eject the second drive when I'm not using it (which is most of the time), and it spins down.

The issue with Fusion drive is you have absolutely no control over spinning down the second drive.

Just a wild guess, but it seems like I can get around 6-7 hours without the HD spinning. That goes down to around 4-5 hours if the HD spins up all the time.
