On older drives, that's good advice and I'd also avoid second hand ones
for the same reasons.

On modern ones it doesn't hold true any more unless you are doing
disc-intensive work like video editing or something.
Take this, for example:

(There is another multi-vendor report kicking around, I just can't find
it right now)
~70 years for the 850 Pro model I suggested in my other email.

However, proper partition alignment is still advisable for endurance and
performance.
