SSD's have improved significantly, and the cell re-write issue has gone away for the most part. As mentioned in the article to hit the lifetime of a 250GB drive in one year, you would need to re-write 190GB per-day, every day, for the entire year. In normal desktop/laptop use, you rarely write more than 1-2GB a day on average -- so that would translate into a 190-95 year wear-life for the drive under normal use. Even at 10GB a day, that would be a 19 year life for the drive. So based on those figures, you would install Arch with your choice of desktop, use it for the day, delete everything and repeat the install/delete every day for 10 years and still be fine. -- David C.
