In the past, that was usually true. But, take a look at the current
pricing of Seagate Exos drives on Amazon [1]:
$372.30 / 16 TB = 23.27 $/TB
$319.99 / 14 TB = 22.86 $/TB
$319.99 / 12 TB = 26,67 $/TB
$249.99 / 10 TB = 25.00 $/TB
$190.39 / 8 TB = 23.80 $/TB
$152.95 / 6 TB = 25.49 $/TB
$161.64 / 4 TB = 40.41 $/TB
$122.85 / 2 TB = 61.43 $/TB
$90.10 / 1 TB = 90.10 $/TB
And, of course, the above prices do not include "everything else" --
racks, cables, interfaces, power supplies, and electrical consumption --
which increase as the number of drives increases. 16 TB drives are
going to have the lowest total installed cost for a given total storage
capacity.
Then again, many small drives have higher performance than fewer large
drives of the same total capacity.
So, it's a balancing act.
