That's a good point!  I just presumed that there is something "better"
about Buffalo drives that I was missing.

In Hong Kong, they actually sell laptops at different prices (i.e.,
same brand, slightly different model numbers) depending on whether
it's made in China or Japan.  Of course, I don't know whether the ones
made in Japan are better; it might be that vendors know the words
"Made in Japan" means they can increase the price.  The average person
will still buy it.

I thought it was the same thing I was seeing.  Or they put a very
expensive product out so that everyone buys the cheaper one thinking
that "it's a great deal".  I'm sure Yodobashi Camera does that from

And I think there should be an "SS" next to the USB symbol, as well.

Hmmm, I'll think about it for my next upgrade.  To process the data I
work with, I need hard disks in the TB range.  So I can't quite dump
the hard disk out yet to an external case.  But maybe if the SSD
prices continue to fall...

Thanks for the suggestions!
