Depends on the disk (magnetic hard drive, density, type of storage (eg smr), flash/SSD etc).
AFAIK for a recent (say, 2010 and later) drive - there's little to indicate random/"smart" patterns are better than just a single pass off all zeroes. Even if you consider an adversary with the capability to analyze drive with magnetic force microscopy.
And q'n'a indicate that single pass sata secure erase is generally considered sufficient - it typically does a single pass, but should also write over all bad blocks etc.
