Afair it would need to write the equivalent of about 1000 times of the Disk size to get near any boundries here . SSD comes with unused cells that will replace defect ones, feature is called 'Wear Leveling'. Two friends of mine ride SSDs for quite a while, so these are elder variants, with no problems. One uses it to play ARMA for better texture streaming . Had the problem that two of my HDDs died shortly after expiration of guarantee .
