My 2012 MBP has now been fitted with a 480GB SSD. Loads much faster now 
Incidentally, El Capitan has that progress bar. I haven't tried anything else since Lion, but Lion didn't have that. Oddly enough it reaches about 50% of the bar and then the wallpaper loads.
What is Trim please? Is that something I need to worry about now I have an SSD? My office laptop (Win7) has an SSD and I have never heard anyone at work mention Trim.
Edit - I spoke to an agent at Crucial in LiveChat and he advised that Crucial SSDs use something called AGC (Active Garbage Collection) which works like Trim, so no point in using Trim. However, he said to turn off 'sleep hard drives whenever possible' in Power Settings - not really any point in sleeping an SSD anyway

trim i believe turns off some things that get written to and from a normal HDD that an SSD does not require.
thats my understanding.
bottom line is reduces read/write to SSD and extends life a little.
from what I read it is recommended to turn it on, unless you have a black list drive.
There are only about 5 that are black listed on mac as trim is not supported.

Keep in the back of your mind elf the hack prevents upgrading further operating systems. You have to remove the hack, upgrade, and if you wish, install it again.
the hack in only a setting hidden in the os.
I if you buy a genuine mac ssd the setting is turned on by default.
only 3rd party ssd you need turn it on manually
so even if i fitted a real mac ssd then I cannot upgrade to 10.11.6 when available?
As the trim is enabled by default on mac ssd.
EDIT:
is safe if you do it this way as keeps the kext signing running.
