3T models were recently atrocious, past few years, whereas 2/4/6TB
weren't. Strangely eye-opening. I'd still want manufacturing drive
dates, model verification numbers, still, were I interested in a 3T
purchase.

Think I've at least one 1.5T model, up there in the outer limits.

HGST, especially, Toshiba, WD, and Seagte have good representatives
among low failures. As well abysmal models to be found more or less
among all.

Although offhand I may not be seeing all the data charts and
abstracts, too lazy to pull up a more compliant browser, I did check
into some of the outstanding HGST stats from a retailer perspective.

You pay for those drives, maybe twice what WD or Seagates sells for
potentially x6-times higher failures. Enterprise, apart from an
actual accountability of the warranty, can seem as extra wrapping
paper for other than a shipping box with at least a sealed OEM bag and
serial no. the manufacturer can link to validate.

Depends. I don't mind paying less, something thereof, half for a
non-enterprise drive with a year to three less warranty
accountability.

White Drives, sold as, is another one on Ebay. The Weirdings. Coming
in from Thailand directly, rebadged for "White", off Hitachi, Seagate,
maybe WD facilities. Translation: "A" major manufacturer. One third
less, or $40 for 2T drives at a minimum norm, meaning accountably
warranted for a reasonable couple years, at $60. And others. Other
angles. Similar angles to be shafted when a 1-yr. warranty, if that,
is found a matter less than appreciably honorable. Among potentials
for other concerns.

Popular site and has an accompanying index, although it may not be
aggressive enough for bloody guts and cutting-edge update purposes.
