> Perhaps we just understand disk failure modes better, and are more comfortable with them. In some ways, predictability is an issue too. SSD typically fail after a relatively set number of write cycles, which doesn't seem too much of an issue until you try to put them into a RAID5 array. I've heard stories of a couple of people trying this, and having multiple drives all fail within hours of each other (usually during the array rebuild). It's something I'd never have thought about had I not been prompted.
