I'm looking at the various Crucial M4 512Gb drives, for my PS3, and noticed that there are 5 difference models but no apparent difference. I tried search for the differences between them but came up short.

What I am looking for is a drive with auto-trim, or garbage collection enabled when idle, big, and fast. and I think the M4 covers all that. But does anyone know what the differences between the 5 are?
Thanks
