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.
