    Lion users with SSD Mac's - "Resume" "Versions" features




    Both feature saves lots of data to Hard Drives. Maybe Versions have small amount of data but Resume feature saves everything open to the hard drive just like in a Windows. No power, resume whenever where ever you stop.

    What I think that those features will reduce health of SSD?

    It can only save what's in your RAM - which is generally 4GB or 8GB, not that much space. Everything that isn't in your RAM is already on your hard drive, in Virtual Memory anyway. Your Mac already does that in Snow Leopard, it's called Sleep Image, and it's a giant file that stores all your RAM when you put your computer to sleep. Resume is the same thing, but it doesn't store the OS (so that rebooting will refresh the OS), which makes the file even smaller.

    Yes, but I'm not sure about Versions though! But I think you can turn it off.

    I'm worried about the lack of trim support for my intel 320 ssd without hacking the o.s. That combined with small writes and lazy garbage collection make me wonder about the long term performance.
