But you shouldn't have to downgrade your memory to install a working SSD. I had 16GB in mine when I upgraded to the Crucial m4 512GB. Not one problem getting it up and running in a very short period of time.
I think some of you are having trouble with the SSDs themselves - I'd return them (and keep returning if needed) until I got one that worked.
Just to beat a dead horse (seems like you got the OCZ working), it appears that you have some issues around your MBP. I have a mid-2011 13" mbp, OSX Lion, 16 gb DDR3-1333 ram and a Samsung 830 SSD (256gb) all running very harmoniously. I had no problems with the ssd install, however, about 2 months ago I started getting beachballs and complete system lag for several seconds or more. The ssd was only 3 months old. I upgraded to the new Samsung 830 firmware and the problem went away. I have beligerantly pushed the thing to make sure it wont cause problems again and it hasn't.
I have trim off, although I had it on originally. However, even after I reinstalled Lion the beachballs still existed until the firmware upgrade. I really hate to say it, but your MBP may have a Sata 3 shielding problem, causing issues recognizing the ssd's at their intended bandwidth. Although they should be backwards compatible, if the speed negotiation is flipping around, this can cause exactly the issues you are having. Check your system profiler to see if you are at full 6gbs bandwidth.
Also, just to mention it, the new MBP (retina) have the same exact Samsung controller from the 830 in their SSD drives now. So any qwirks with them should be worked out on the next firmware update.
Yeah, I think you're right.
However, here is what is said by system profiler :

And now works with no IO/Errors even if I shut down computer because of kernel panic.
Note : I removed sata cable of MBP and clean with a air spray.
iFixIt.com sells replacement shielded cables for the MBP. I don't condone 3rd party equipment for non user-upgradeable parts, however, with this issue you may look into it. Other than that, I am out of ideas. I have never had a kernel panic with the SSD. When I installed Crucial memory in the MBP, initially I got kernel panics. Then I RMA'd back to NewEgg and got Kingston (my favorite brand of memory) and have had none.
Kernel panics are usually a symptom of clock timing issues, where the bus or memory clocks hang and dont allow the kernel to complete the required processing within the current clock cycle. The hard drive should not cause this unless it hangs during communication without warning, caused by hardware problems on your computer.
Have been using the Samsung 830 in a Macbook Pro Late 2008 for about 8 months now without any problem.

I have just bought the samsung 830 series online waiting to be delivered. I still have applecare on my mbp, will their tech support phone help me through any problems I encounter or is that a stupid question because its a third party hardware (although I hear they are using these drives in the new retina model anyway).
is that a stupid question because its a third party hardware (although I hear they are using these drives in the new retina model anyway).
I think you've answered your own question.
in any event, do not expect to get the same issue as others are having....different factors play on why one is having issues while others aren't having any.
good luck.....the 830 seires is a good drive and it's the one being used in the Retina Macbook PRO
I had the Samsung 830 and had issue with it (beachballs). I really thought Samsung was the king of SSD's and may very well be, but not for me. So I returned the Samsung 830 to Amazon for a refund. After a little more reasearch I decided on the Crucial M4 series SSD. I've had NO issues at all with the M4 (5 months of use). In fact I like Crucial M4 SSD's so well I purchased (10 days ago) one for my new 2012 MBP 2.6GHz i7, HR antiglare WS (USB 3.0).
One thing I learned about SSD's that I instutited from the get go was to disable "Put Hard Drive to Sleep When Possible" in "System Preferences" "Energy Settings". Others have disabled sudden motion sensor via Terminal but I think my method is better....IMO.
BTW, Im getting 285 write and 502 read, 17.6 second (average) startup in the 2012 MBP. A real screamer, the fastest computer I've ever owned and Im 54. Geekbench score 12096.
P.S. Almost forgot Crucial firmware upgrade is easy using MBP, not sure about Samsung. I upgraded the first M4 firmware from 0309 to 000F (no problems with firmware 0309). My newest M4 came with firmware 000F.
