However, such a drive is getting heavily into diminishing returns territory.
e.g. a 20TB drive from Seagate is $500. A 4TB drive is $70, 8TB is $140. Getting the same spend in smaller capacity drives would give you 28TB in the 4TB drives and 24TB/32TB in the 8TB drives (for $80 under/$60 over).
Add in a second to rotate and you're spending $1000 in drives, assuming these 26TB drives replace the 20TB drives at a similar price when they trickle down to consumer hands.
You have to factor in the power usage of having multiple drives spinning. Though I’d agree that smaller drives are better when you have a drive failure, as resilvering is quicker.
