At best that would be how much rewriting the cells still have left. Just as in hard drives there is no way of knowing when a random failure, due to a broken bond wire or a bad solder joint will occur. "Life time" can be calculated for hard drives as well, but that doesn't really mean it won't crap out tomorrow after claiming to have years left. If you really care about your' data, Raid (preferably raid 6 or better) and backups (preferably off site) are the only way to go. The issue is not usually end of trusted life, but rather random failure. I've barely managed to recover failed hard drives, That is less likely on SSD though possibly less likely to happen. |
