I have the OCZ agility 4, 512 gb in my MBR 13" i5 and 16gb corsair and it runs prety nippy and fast. might not be as fast as the samsung. but hay for $340.-- on amazon who can beet that price for a 512 GB SDD.

Decided on the SanDisk 240GB Extreme for a mere $180. Works fine. Used Carbon Copy Cloner so that the Recovery Partition was also duplicated.
Slightly off topic, I found CarbonCopyCloner to be quite user UNfriendly, especially compared to SuperDuper. CCC does have a larger more accurate progress bar, and it did copy the Recovery Partition, whereas SD does not.
CCC needs a much better GUI. The sequencing and wording needs much help.

Here are my experiences with an Intel X-25M 160GB drive used in three different macbook pros (2009, 2011 and now mid 2012). This drive is now four years old and always worked reliably in the former two macbooks.
Last week I moved it over to a new macbook pro 2012 (non retina version) and it worked fine there at first.
Then one day into operation the OS updated the firmware, which must have enabled some new advanced AHCI features (maybe NCQ?) for the first time. The drive immediately failed to boot. I could fix this with a firmware update of the drive, but now got the first kernel panic in four years today (and it mentioned AHCI).
So clearly Apple did recently activate new advanced AHCI features that this old Intel drive is not supporting.
I am looking for advice now on what drive to upgrade to.
Is there a list of officially supported SSD drives? I would tend towards one of the higher grade (520?) Intel series again because the reliability after four years made me a fan (the drive still reports 99% health after all around the clock useage for four years).

Bumping this, I have hit the same issue. The MacBook Air and MacBook Pro mid 2012 2.0 update breaks support for my SSD and the system won't boot anymore.
Anyone whom can confirm som SSD that will work with this update?

As I said you can get the machine to boot fine again by simply updating the firmware of the Intel drive. To do this however you need another PC, ideally one with Windows, cause the Intel tools for mac are not as good.
For the record: I only had one crash of my machine since this update and am still using the "old" Intel drive daily.

Forgot to mention that I don't have an Intel SSD. Mine is a OCZ Octane s2. I have updated to the lastest firmware and the small update called MacBook Pro and MacBook Air 2.0 update (Fixes graphical and USB issues) breaks boot on it. So far I havn't found a fix, so im skipping that update for now.

Does any of you have anything to say about Samsung 840 pro -series SSD? It is newer than 830, and the specs look better too...

I have changed two Crucial M4 (128, 256). Speeds according to Blackmagic speed test are 250write/500read. Never had an issue price is very low, power consumption is low, updating firmware is 5 min job(released 3 updates since last year).

Some additional information… Samsung is starting to push out some amazingly fast drives as well. The only issue/concern is the method for the storage medium. In Samsung's newer drives, they are using TLC. Here's a quick breakdown on the technologies:
Bits: 0 or 1
Stores: 1 bit per cell
Server/Enterprise Class Drives
(Some even use two cells to store the bit to further reduce error prone results)
MLC (multi-level cell)
Bits: 00, 01, 10, 11
Stores: 2 bits per cell
Consumer Class Drives
TLC (triple-level cell)
Bits: 000 through 111 (inclusive)
Stores: 3 bits per cell
Historically limited to USB drives due to performance and reliability, now entering the consumer class drives
While the latest generation of Samsung SSDs [on paper] have phenomenal capabilities, one might suggest some reservations about these drives. At least until this new generation of drives has had more exposure, history and usage in the market.
FWIW – The OWC Mercury drives aren't slouches, but they aren't the fastest either. They are faster than the stock Apple SSD drive – most aftermarket consumer SSDs are too. The key with the Mercury drives are that they make it easy for you to replace the stock [spindle] drive with an SSD that is above the median SSD performance rate. Plus nice packaging with excellent instructions.
The more interesting point is that OWC holds back disk space – which is reserved for remapping of bad cells. A 240GB Mercury is actually a 256GB SSD with ~16GB of "cell space" held back for remapping and wear leveling (I think they state "7%" being reserved). So you do pay more per [usable] GB with the OWC drives as well. I think they are the only consumer grade drive that does this. So from a data retention perspective – they are excellent. You don't have to worry about wear leveling or TRIM support [necessarily] because of their design. Two things that many other vendors should probably consider. General Consumer use = B+ / A. Power User = B– / C+.

Why not just use the RESTORE feature of Apple's Disk Utility to do the clone? Won't that copy the Recovery Partition exactly as CCC does?
I visited that SanDisk product page on Amazon, but I was scared off by what D.Mclean wrote about poor performance in his 2009 MacBook. So for now I am still eyeing the $229 OWC Electra 6G 240GB (priced $0.99 lower than the 3G, for some reason) for use in a 5,5 MacBook Pro 13":
