These *ARE* "commodity" disk lines!!! They come of the _exact_ same
lines as their desktop versions -- _exact_ same capacities, density,
etc...!
The Seagate NL35 _are_ the Seagate Barracuda 7200.8!
The Western Digital Caviar RE _are_ the Western Digital Caviar SE!
They roll off the _same_ lines!
These are _not_ 18, 36, 73 or 146GB "enterprise" capacities, but 100,
160, 200, 250, 300, 320 and even 400GB "commodity" capacities! These
are those same leading-edge capacities, at the same fab levels, maybe 1
series removed from the latest (e.g., Seagate now has a Barracuda 7200.9
that go up to 125-133GB/platter, 500GB capacity).
You asked me where I got the 400,000 and 1,000,000 hour MTBFs from. I
told you no one offers the 400,000 hour MTBF on the desktop devices
anymore, but you _could_ find the 1,000,000 hour MTBF number on the new
crop of "near-line, 24x7 network managed" commodity disk capacities.

Huh?!?!?! What data "contradicts" what I presented before?
The vendors have taken their "commodity" capacity drives and offered a
new set of 1,000,000 hour MTBF versions that test to higher tolerances.
And you pay a premium for them!
But they are _not_ the "enterprise" capacity drives with 1,400,000 hour
MTBF drives. Those come off entirely different lines! Different
platter densities _entirely_!
