The Samsung 830 SSD in my always-on server finally experienced its first failure to erase a block at almost exactly 25 Tb written over 2.56 years of operation (27 Gb/day)! That's a bit poor in fact, only 728 of the erase cycles have been used so far, and the 830 is one of those old MLC drives with 3,000 erase cycles, so that's a bit early to see a failure. No data is corrupted, the drive keeps some spare blocks which it needs to consume before that would become a worry, and it's used two of five hundred of those so far. They were great SSDs those 830s, way over engineered for the price.
