Another point to add is that you have to get past 4TB before you get NASware 3.0 drives (the new refresh-cycle ones), due to clearing out inventory, first. The 4TB and lower ones are part of the refresh, though. Resellers like NewEgg are pricing the 2.0 ones to sell, to sell-off inventory. Since the recent inventory seems to have a lot of DOA drives in it, I'd rather go with 3.0. But, NewEgg doesn't even sell the 3.0 ones, below 4TB, at this time (unless I'm just missing the secret on how to get them). Even if there's no benefit for TiVo use, I'm holding-out, for something that's not part of the bad batches of drives plaguing the market. Considering the 3.0 NASware "improves" things that were part of NASware 2.0, like how the drive handles power outages, I worry the "improvements" are more like "fixes". So, I want the 3.0, or I'll wait it out, before buying any more 4TB, or less, drives made by WD.
