What do you think most of the new "near-line" models are?

higher/better tolerances, even though they come off the same
line as the OEM/desktop ones.  ;->

Exactly, when it comes to the same mechanics.  Some products
are labelled, warrantied differently and sold at a difference
price for a different market.

There _are_ still drive models that _are_ manufacturered
differently.

In the 3.5" space, the capacities of 18, 36, 73, 146GB are
"enterprise" 24x7 rated.

The capacities of 100, 200, etc... through 500GB are the
"commodity" 8x5 rated.

Some of the "commodity" types are now being tested to higher
tolerances and sold as "near-line, network-managed" 24x7.
