I know the joy of fiddling "under the hood" with the hardware, and can appreciate your desire to do so. (Does anyone remember S100 computers? Ah, the smell of solder! ) There is also something to be said for the mbp-r - I like mine, despite its nonmodifiability (is that a word?)

It occurred to me (maybe you mentioned it) that this is more likely an Intel issue as Intel probably actually designs the chipset. Its a system limitation when the port runs at half speed (eg 2009 MBP), it's a BUG when it crashes the system (2012 MBP)! The port is rated at 6 Gps, it connects at 6 Gps and crashes or causes major problems. It would be better if it connected at 3 Gps a and worked without issues (other than slow speed). Regardless, it needs a firmware fix.

It is not an Intel issue. Intel makes the chipset and Apple supplies the drivers/software for it. On Windows Intel does supply the base drivers/software and to my knowledge there are no problems on Windows.

I finally got a Crucial M4 256Gb SSD to work! This was the 3rd SSD I tried. The Samsung 830 & OCZ V4 are basically unusable with the current version of OSX firmware. There's definitely a firmware issue as of this writing. Everytime the machine wakes up from Sleep it ejects the SSD causing the machine to lock up, forcing a manual reboot. It took 2 visits and 4 hours at the Genius Bar to figure this out (I'll have to hand it to the Geniuses, this model has only been out for a month and they hadn't seen this problem before, the were very helpful). The only way the machine would work was with the original hard drive. Refusing to give up and being a glutton for punishment, I decided to try a 3rd model, I knew there must be some SSD out there that must work, Apple gets their SSD from some supplier. The Crucial M4 has been around for awhile, I figure maybe Apple had tested it, and the price on the 256 Gb is really good vs. competition ($180 at MicroCenter). So far, works like a champ (1 day). I get 502 MB/sec READS, but only 242 MB/sec Writes on Blackmagic DiskSpeed tests. My MBP boots as fast as 6 seconds!!! Woo Hooo! Just hope it lasts!

Halfmoonh4, are you talking about your above experience with your SSD in your main HD bay or the optical bay?
I've had great performance of my Samsung 830 in the main HD bay.
I have a Crucial M4 64GB SSD but it's SATA iii.
I've read that SATA ii drives will work in the optical bay. I bought a Mushkin 120 GBSSD SATA ii for the opitcal bay. Going to install it today. I'll report back when I finish installs and tests.

Yep, my Samsung 830 and OCZ V4 both crashed the main bay. The SATA III Momentus XT Hybrid crashes the optical bay. Currently, I'm using the 5400 rpm apple drive on the optical bay with no issues. I'm waiting for a SATA II 7200 rpm WD Scorpio Black to try next.
I think I must have just got a bad Samsung, like yours, it should have worked. But the Crucial M4 works, so one half of my problem is fixed.

Ok. I decided since i was opening up the optical bay, i might as well test my Crucial C300 128 GB Sata3. I've read forums and discussions about installing a SATA3 drive in the optical bay in the Macbook Pro 13" Mid 2012. People say it shouldn't and can't be done but so far so good although my speeds aren't as high as I would like in the optical bay (Crucial C300). The speed on my Samsung 830 in the main bay seem to at 6gb/s speeds. Not sure if it's the Crucial C300 or the optical bay connection. It reads 6gb/s in system info, link speed and negotiated link speed so I don't know what to think right now. It's only been an hour so I'll report back if there's any issues.

SSD's - The crack cocaine of personal computing!
After failures / incompatibility on 3 different drives, I've landed on Crucial M4's. There's some SATA III firmware issue that just makes the new Mac very finicky. Maybe a future firmware update will fix the problem, dunno, but here's what I've found to work.
re: Crack .... After I got the 256 Gb Crucial to work in the main bay I had to have more, your post inspired me to put a 512 Gb SSD in the optical bay as the 2nd drive (took the DVD player out) as my data drive.
FYI, people may find this pretty useful.... I've been using the USB3 to SATA III adapter (its a detachable pigtail) off the Seagate GoFlex to hook up bare harddrives, its awesome (see below, USB3 is faster than SATA II on the tests I did)
Anyway here's my NERD log of observed drive speeds using Blackmagic Disk Speed Test.

I've read the 13" has problems with the optical bay. This isn't very surprising as these MacBook Pro's have a history of having flaky connections. I've ran into the same problem that prevented me from setting up a stripped raid in my late 2011 MBP but it's been fixed after the Mountain Lion update. (video link with detailed notes.)

All this is really strange.
I have a Samsung 830 128GB working with no issues on my main port in a Mid 2012 13" MBP.
But it doesn't work at all on the SuperDrive Port.
Maybe the EFI Update fixes some of the issues, but I can't try it our right now.
