let us know how it went?

It has arrived. Before i break the yellow Attention Seal, Just a couple of questions. It is firmware version 0001, So i know i have to update the firmware to 0002. After installation of the SSD, Do i proceed with the firmware upgrade or do i install SL first? I am doing a clean install of Snow Leopard. Second question It says it is a SATA 6GB. What is the difference between SATA and SATA 2?

Yes, upgrade firmware first, be sure to download the right one from Crucial. I did mine in a PC but there have been reports of Crucial fixing their firmware loader to be Mac compatible.

Difference is 1.5Gbps. SATA1 has a bus speed of 1.5Gbps and SATA2 3Gbps, same physical connector.

Be very careful with the SATA connector in the MBP, it is very delicate so treat it like a piece of tissue paper.

I installed it last night. I got a little worried because I accidently tugged the SATA cable a little, But all in all, It went well. After installing the Firmware, I manually restarted the computer by manually shutting off the power button because there was no other way to restart. The firmware disk i made was done on my PC. Does this matter?
 
No, it doesn't matter. It's just an iso of a very cut down linux distro which will boot on either a PC or a Mac.

And for the record, TRIM support is available to Apple supplied SSD's on 10.6.7 onwards, but can be enabled for all SSD's by use of a hack. Search for OSX TRIM enabler. I have it enabled on my 10.7.1 Lion install with my Crucial M4.

You need the hack for Snow Leopard but you can enable TRIM for all SSD's in Lion through some simple terminal commands.
 
My understanding is that the terminal commands that you mentioned are being performed by the hack in SL. It's the same driver for both versions of the OS that is being patched. Both commands and hack are removing the string check that looks for an Apple SSD before enabling TRIM.

Read this article. The hack app is actually installing an old kext from 10.6.8 and is not just patching the current kext. Running the terminal commands from the linked page is the better option IMO.

Yeah, I just found that link from a separate page discussing this. I would agree, enable TRIM through the terminal, not via the hack.

For anyone who has used the hack, you can boot from the Recovery HD and copy the correct IOAHCIFamily.kext back to your main disk and then remove the cached kexts and reboot (which I what I've just done).
 
Just installed the M4 in my brand new 15" Lion MBP - upgraded to 0002 firmware and it is insanely fast, at least twice as fast as the one in my 2011 iMac. Awesome SSD.
 
Im having a great time with this SSD. Its very fast. I did my research on Crucial SSDs and it turns out if i let my MBP idle a few minutes, The garbage collection feature will automatically keep the drive in top shape. I highly recommend this SSD to anyone. The clean install of SL , The updating of the firmware was all a breeze.

I agree, I liked the 256GB so much I went for the 512GB plus treated the machine to a 8GB RAM uplift and a clean Snow Leopard. It is just so fast and silent too.
