Just wanted to post up that I succeeded in creating a fusion drive in my Mid 2010 MBP 15" last night.
My setup:
Optical Bay Adapter: Bought off ebay from nimitz**
HDD: Western Digital Scorpio Black 500GB
SSD: Samsung 830 Series 128GB
SuperDrive Enclosure: Bought off ebay from nimitz**
First thing I did was redownload ML 10.8.2 and recreate my bootable USB install HDD. While doing this I made sure my Time Machine backup was current.
Then I installed the optical bay adapter. It's metal and seems very well made: the drive fits great and the adapter fit perfectly in my MBP. I kept the HDD in the stock location and put the SSD in the adapter.
Once I had this done, I used the FD guide from Macworld, which I found to be very thorough. I just followed along and everything went according to plan.
After I made the FD I installed OS X with no issues and had it transfer my TM backup over. That was it, and I now have ~640GB of FD space.
First impression: excellent. Safari, System Preferences, Mail, etc. now open with one bounce, whereas before it would take 3-4, maybe 5 bounces. iPhoto now opens in about 1/2 the time it used to. I haven't tried to force it to move files between the drives, but I can tell the applications are definitely on the SSD. I've never used a laptop with a traditional SSD setup before, so I can't compare it to that, but compared to my 7200 RPM HDD it is much, much faster at everyday tasks. Overall I am very happy with the setup, and would recommend it for anyone who doesn't want to/care enough to deal with organizing files on separate SSD and HDD partitions. Not that that's overly difficult, but this is just so easy.
One issue I'm having is that while I was able to restore from TM during the initial setup, and Migration Assistant can still see my old TM backup, Time Machine itself does not see them. I can select the drive in System Preferences, but when I open TM it just shows my current state. I'd like for it to just continue backing up from where it left off before I created the FD. Is this possible? And if so, how? If it's not, and I need to start fresh, how do I access my old backups? When I try to manually open the backups on the drive it says "this volume is unavailable" or something similar.
