I'm in the process of installing my 256GB Crucial M4. Will post a thread later on my experience. I'm wondering - is it really all that bad to NOT disable the safe sleep? I have enough room now, so not worried about losing the 8GB of space. But is it really damaging or detrimental to the life of the drive in any way a normal user will notice to always write that data when you close the lid (say happens 5 times a day)? I kind of like the security of it, plus I also really do not want to have to stress or worry about managing my SSD, worry about excessive writes, etc. I want to just use it, enjoy it, and forget about it. In the same vein, probably not going to enable or worry about TRIM unless I experience issues. What say you, guru's?
