Which blows your silly claim completely out of the water.

Even sillier.

Thats nothing like a vanishingly small percentage.

Even sillier. You dont have to overload it to need more than 2/3TB.

Even sillier when PVRs would be supplied with the larger
drives if they  were available and reasonably priced.

Or are buying a PVR.

Which they will certainly do when the larger
drives are available and are reasonably priced.

> and 6) Have a PVR that can only handle a single drive.

Even sillier.

Repeating that stupid pig ignorant claim changes nothing.

Taint a narrow example at all, fool.

Not on the need for drives bigger than 2/3TB they dont except in the
sense that operations like google need immense amounts of storage.

And they aint alone in that.

Like hell it does with the immense amount of storage they need.
They'd have plenty of spindles even with drives bigger than 2/3TB.

Wrong, as always.

Not with the immense amount of storage operations like
google need, they already have vast numbers of spindles.

Irrelevant to that stupid claim you made about MOST MANUFACTURERS.
