G'day y'all, On my 21.5" late-2013 iMac, Activity Monitor shows about 300MB written to the internal SM0256F SSD every 5 minutes or so. In the space of half an hour when idling, almost 2GB of data is written to it. I'm worried about this because I've heard that SSDs have a finite amount of writes that it can handle. This problem doesn't occur on my 27" iMac and both my rMBPs. On a side note, no external hard drives are connected to the iMac as well.
