I never used an SSD before, but I have been reading a lot about it lately as I am intending to buy an iMac with SSD. My questions here is will SSD degrade over time? I heard that writing speed will degrade over time, how true is that? What is your personal experience? I like to download a lot, that means I also delete a lot. If I download directly to my SSD, will it shorten its lifespan? Also will surfing the internet shorten its lifespan? Since browser caching is constantly saving things on the SSD? Kindly share your experience. Thanks.
