yes, copying to the hard drive. Nero reports read speed as about 2875
kb/s, varying up and down every few seconds. Since 1x speed is 1350
kb/s, this is about 2x speed.
"The data transfer rate of a DVD drive is given in multiples of 1350
kB/s".

yeah. I got the cheap DVD-RWs, so this is most likely 2x. I'll try
and buy a few 4x, and see if this improves any.

Confirmed in Properties > Hardware; yes this is a Toshiba SD-R5372, so
no the web vendor didn't cheat me. Whew. :)
