SSD write lifetime is longer than you think.
"We assume perfect wear leveling which means we need to fill the disk
2 million times to get to the write endurance limit.
2 million (write endurance) x 64G (capacity) divided by 80M bytes /
sec gives the endurance limited life in seconds.
That's a meaningless number - which needs to be divided by seconds in
an hour, hours in a day etc etc to give...
The end result is 51 years!"
