Both are high overhead option to protect against disk data scavenging.
Is left-behind data scavenging something you need to worry about?
Does any of your applications have a habit of reading raw disk data,
expecting zeroes when the application has not written to the area
being read?

As per Michael, /erase which is  is equivalent to /ERASE=(INIT,DELETE)
writes to all blocks.
That takes a while which may bot be important to you.

/HIGHWATER can bite you when you don't expect.
Some copy or SET FILE/END which effectivle lock up the volume for a
while.

I woudl leave both of for a hobby environment and even for a well
understood/controlled production environment.

Good luck,
Hein
