Crucial M4 or C300 SSD, definitive to patch trim support on or not, and best imac ssd install guide

here is some info to back up the idea that even even crucial suggest that trim being on is good idea and anandtech say you should run with trim on for the M4 even though it has garbage collection, I got this info from another site :
apple support forums M4 trim discussion post
in the above forum post it references two articles below about crucial SSD’s and whether garbage collection is sufficient, the jist of it is, in the crucial c300 and M4’s ssd drives case it is worth running the drive with trim on.
crucial forum post 1
crucial forum post 2
and an anandtech article clearly stating that the crucial M4 needs an os with trim support to make sure that performance doesn’t degrade long term, with performance metrics to back it up.

and if you need help in enabling trim i recommend to enable trim using this method :

if anybody is finding that there trim support got disabled in 10.8.3 12D78 or the instructions to enable trim didn’t work with their ssd on ML 10.8.3 12D78, then I recommend having a look at this python patcher,
python trim patcher & instructions
but bear in mind its not for amateurs or the faint hearted, but it worked for me in getting trim support enabled on a crucial M4 128gb drive when the terminal commands in this article didn’t work. place the python file in root and sudo run it with the apply argument as noted in the instructions and bear in mind instruction get the file name wrong compared to that in the zip so you will have to be aware of this and correct for it. please read the instructions etc.

if you have got trim enabled a while after the SSD has been in use ? and what to clear freespace on the SSD to ensure that trim and Garbage collection is done, then >

“You can do it by booting into single user mode (CMD + s) and then typing fsck -ffy at the root prompt and it will erase all free spec and prep for TRIM.”

once the fsck command has worked enter

to restart the computer, and a fuller explanation re fsck process here why apple has decided to remove the erase free space option for SSD’s i have no idea ? except they presume TRIM has been on since install, although I know of plenty of users who have apple SSD from purchase that claim they have come with trim OFF, so i’m not sure thats a valid reason to take this option from the GUI user ?

not at the point of needing to enable trim … as you have yet installed one ? Need a guide to install an SSD in a mid 2011 imac ?

More Lion woes, erase install the only way to get lion to perform properly, upgrade installs glitchy as hell

Network links/aliases in dock not working ?! in Lion they no longer automount the associated network volumes if the login is stored in keychain, or offer up the dialogs to put in username and password when the login details have not been stored in keychain, this worked fine in snow leopard and was extensively used by many in my office environments. There are too many things that go wrong with an upgrade to lion as it stands.

Why Oh why dont I have a preinstall option to do a good old “archive and install”, So i get a clean OS install and then can pull in only user data that will be known not to conflict ? and reinstall apps. I know Lion prefers a clean install, because I have four machines that are all now slow glitchy and rubbish by the users measure and level of complaint after a normal Lion download & upgrade process, apples now standard way to install the OS ? I took one of these machines, backed up 250gb of user data via ext FW800 ! YAWN even that was a pain because you made the user library folder invisible in lion ? and made the copy function not copy invisible files ? Dangerous from a manual backup perspective indeed! I then erased the drive, did a pure clean lion install from a manually created install on a Hard drive from the ESDinstall img. Another problem recovery boot install manually re-downloads the installer image everytime! thats total !*$! from my perspective, imagine I need to do this on 5 machines Meaning I have to download a 4gb file 5 times ? not everyone has a 100mbit fibre connection on an apple campus !!, Then I hand reinstalled all apps, selectively manually copied back the user data, avoiding most library and sys related files that werent necessary, Now the machine runs as it should do normally and without so many issues ? total time 10 Hours just to do a full clean install of their complicated setups. Why Must I Erase a drive to get a completely fresh install of Lion on these machines ?????? this involves backing up 300gb of data and copying it back again from a support perspective its a disaster time and expense wise for my clients ? a £20 upgrade costs them a fortune in support hours to have their machines working normally ? just so they can have calendar and address book syncing back !!!! the only feature they wanted to keep using.
