I am looking for a pair of HDDs with a capacity of ≥2TB, then pop them into an external enclosure with RAID 1. Then second similar enclosure for a secure backup.
With 2¾"-HDDs now offering such capacities, is there any advantage/DISadvantage is choosing this over 3½"? Certainly, for the latter there would be less energy=heat-generation.
(Less important, but intersting: more and more have 3TB - so go for them if price & maker is good?)
