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 
to soon.

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.
