Prevent SSD wear by using SmartSleep
Tangentially, if you are concerned about SSD wear, it might be worth your while to use something like SmartSleep to change the OS X behavior from "sleep & hibernate" to "sleep only".
every time?
Is it really every time? I thought only when battery is low. Surely it takes longer to read/write 8GB, even on SSD, than speed of OS X's sleep/wake cycle.
every time?
Unless my understanding is badly flawed, it indeed is every time.
every time?
Yes AFAIK, its written on sleep every time, and only read back if the battery has drained and the RAM contents have been lost during the sleep (so most times you see the fast wake from RAM, and occasionally a tens of seconds wake from disk).
every time?
So the part that totally blows me away is that it appears to really write all of the contents of RAM out to the sleep image.

I guess you're right for the laptop Macs. I think the default behavior for iMacs and Power Macs is: sleep:machine will go to sleep only (saves state in RAM only, power supply keeps RAM contents). Edited on Jan 05, '11 04:24:52AM by QuickSander

Performance also affected by unnecessary writes (no TRIM in Mac OSX)

"Still, it keeps puzzling me why there are a lot of users experiencing measurable slow down (on Mac OSX without TRIM support). Is this caused by the wear leveling algorithm for which it gets tougher and tougher to find unused cells??"
