Suppose you want to ensure at least 99% efficiency of the drive. At
most 1%
time wasted by seeking.
This is practically impossible on a HDD. If you need this, use SSD.
Lately, Richard, you're saying some of the craziest illogical things I've
ever heard, about fragmentation and/or raid.
It is absolutely not difficult to avoid fragmentation on a spindle drive, at
the level I described. Just keep plenty of empty space in your drive, and
you won't have a fragmentation problem. (Except as required by COW.) How
on earth do you conclude this is "practically impossible?"
Drives seek, there isn't a lot you can do to stop that.
