Shooting down your ideas would mean that I REFUSED to try your suggestions.
What I did was to ACCEPT each of your suggestions, try each of them dutifully to the letter, then report back that you TRASHED my computer.
What you are doing is to harass and blame me because you are too childish to admit you were wrong.
SHAME on you.

Really? Are you serious? From where I’m sitting on the sideline the SHAME should be all on you pal. You’re the one who came on here with the attitude and accusations. You have 2 very knowledgeable & experienced people here trying to help you and all you can do is spout unjustified culpability and insult them?
Wow! All I can say is I wish you luck. 
(I could say more, but I’d probably get myself in trouble so I won’t.) Feel free to attack me for my opinion too.
Seriously, I am past caring. It is all down here in this thread in black & white. You clearly have issues of some kind and I for one will not be taking the blame for something you have done. I deal with these kind of issues for a living but have no desire to help someone with an attitude fix their technical issues.

No, SHAME on you.
Both the guys you are trying to argue with are (a) being very helpful and (b) 100% correct. TRIM in OSX works perfectly with the drive with either firmware (I know, I have been running it for weeks). And enabling TRIM in OSX do anything to trash the drive. It’s just an OS setting.
I might add though…
We could really do with a native Windows (or Mac) firmware update utility. Since the linux-based ISO will not boot a 2011 Mac Mini or Macbook Air, users of Sandisk SSD’s on these platforms (i.e. me!) has no way of updating the firmware.
I might also add that adding a ATA Secure-Erase command to the utility would be most useful as well. Seems sad to have to resort to using other people’s software to maintain a Sandisk drive, doesn’t it?
There is a Windows tool availble from this site which will update the firmware - not sure if it has a secure erase feature or not but it would be handy if Mac version was released.

Another user had a similar issue and was able to find a solution by disconnecting other drives. see his post below and let us know if it helps.
Is there a method for getting the firmware update installed and the 240GB SSD working on an older MacBookPro 4,1 (Intel Core 2 Duo, late 2008)? From the forum postings, it looks like you need to install it in a newer Mac to do the firmware upgrade.
Or, would a brand new SDSSDX-240G-G25 already have the necessary firmware?
It depends on when the drive was manufactured. You can check it in system information. If you have R201 no need to update.
Since you have an Intel based Mac it may work. It should work on any x86 based machine. Download the ISO in the stickied thread and give it a try. There are apparently some hardware issues with some older hardware that SanDisk is looking into. If your update freezes at loading bzimage or ramdisk unfortunately there is no fix at this time.
Guys thanks for the tips.
However, let me spell this out for the avoidance of confusion:
The ISO once burned WILL NOT BOOT a 2011 Mac Mini or Macbook Air.
It is not a question of SSD compatibility, nor firmware level nor other drive being attached nor anything else. The ISO will not boot, period. It falls over almost immediately with a cannot find /efi/boot/boot.iso error.
So everything else is irrelevant. As it will not boot, you have no option other than to take the machine apart to remove the SSD and then update it from a PC or some other box. This really is unacceptable.
PLEASE Sandisk, get yourselves a Mac Mini and try to boot your ISO disk. It does not work!
Having a similar problem with the Ultra firmware update. It appears that the ISO will not boot from a USB CD drive - period.
Memo to SanDisk - not everyone has built-in drives anymore!
I have a late 2011 MacBook Pro. I installed the SanDisk Extreme, formatted the drive using Apple Disk Utility from the Snow Leopard installation disk and then restored the drive from a Time Capsule backup. The drive works perfectly and is probably 3X faster than the 500GB OEM drive that it replaced. My computer does seem to run hotter and it freezes sometimes, but I also installed 16GB of new RAM while I had it open. I’m running 10.7.4 on this computer which has dual 2.7 GHz Intel Core i7 chips.
And for SanDisk, please come out with a tool kit for Mac. Your competitors have already done so!
i agree with tombstone’s comment above. mac support for extreme series is a must. i believe macbook pros need the speed of good quality ssds for maximum speed and efficiency. not having ssd in a macbook pro is like using only the 50% of the power it has…
i’m planning to buy 3 of the extreme 480GB ssds as soon as the negotiated link speed problem is resolved via an updated firmware…
+1 cant get the firmware update on MBP 4.1 - early 2008 - please add OS X support
I unfortunatly begin to regreat my new Sandisk SSD 240GB. I should have read this forum before buying my new SSD. To me, sandisk is a very good company as I also own a lot of SD and CF card for my nikon cameras. But now, I am a bit disapointed.
And to add to that, my SSD doesn’t even write at 500MB/s. It caps around 275MB/sec.
Seriously sandisk…
I suggest you read up on the Sandforce controller that is in your drive - writing data will vary from between half the full speed to full speed depending on the data content that is being written. Compressible data will be written at full speed, Incomrpessible around half that and of course a mixture of different types will write somewhere inbetween. This affects all drives based on the sandforce controller, not just the Sandisk.
If you forget benchmarking and just use yoru drive you will most likely not notice and be very happy with the performance - I know I am. The fact it was the cheapest drive at the time and has been 100% reliable for me so far just cement my satisfaction.
you know donka, I personally don’t care about controler. It’s been 3 weeks now since my last post and now my readin is 475MB/s insted of 500 and write is 240 instead of 275.
There is something to worry
There should NO reason for Sandisk (or any other company supplying LSI-SF conrollers in SSDs) not providing fully-optimised, fully-operational SSD firmware all of the time. That goes with the territory. Would anyone normally accept, say, GM or Ford, supplying and servicing a partially-tuned automobile? Worse still, a new automobile that only ever runs on 3, 5 or 7 cylinders? 
@Floydstyle SSD drives performance will diminish a bit through time if trim and garbage collection are not working effectively I.e. enough idle time for them to complete their maintenance. If you are regularly benchmarking your drive you stand a good chance of accelerating this degradation. Without benchmarking, do you notice any difference in performance?
Is anyone here using a Sandisk Extreme SSD 480gb in a new macbook pro (mid 2012)?
