Not really. All drives have errors. The higher the areal density and the
larger the capacity, the greater the likelihood of unrecoverable errors.
I've read a few articles recently about how we need to find a different
approach to fault-tolerance because current RAID technology will not be
able to cope as disk capacities increase. Even with very fast bus and
drives, it takes uncomfortably long to rebuild arrays so it can't come
However, TLER *might* have something to do with "we'll separate the
drives into consumer and pro lines and charge more for the pro lines
because we can". Most consumers don't care about this issue and are
unaffected by it. Those who do care about it grumble, pay more, and move on.
