Heh.. if at all possible, my own highest priority would be to avoid shingled (SMR) drives. The Seagate 4TB/8TB ones I had/used here not long ago have ALL turned out to be duds. 100% failures. I believe I still have a couple of RMA units (after exchanging the original duds) and those are treated as "untrusted".

Never again.

My personal philosophy/priorities when acquiring new drives:

-- Solid-state drives (SSD) if possible (currently up to 2TB).
-- Any brand of SSD is better than any same-size mechanical drive.
-- Anything except an SMR drive.
-- Avoid Seagate if possible.
-- The old (2-4 years ago) WD "Red" drives were excellent (pre-SMR).
-- Hitachi HGST drives are awesome, but Hitachi no longer exists.
-- The 14TB WD (Hitachi) drives I picked up last year are superb (WUH721414ALE6L4)
