[lug] Big External USB copies and Speed

My experience has been that creating one large file is MUCH faster than
creating many small files.
IOW, use tar to backup a directory rather than copying the directory.
Actually, I found tar over SSH to a second computer to be faster than tar to
a USB drive. YMMV.

Subject: [lug] Big External USB copies and Speed
I'm doing some 1 Terabyte backups to external USB drives.
In the past I've heard comments that:
the limiting factor is really the USB speed
some brand drives are way faster than others
the most important thing is: are you copying big contiguous files or
massive numbers of little tiny files
Anybody have an estimate on how long a 1 TB copy would take?
