Zos said what I was going to say.
You will not feel a difference between 7200 and 5400 rpm drives in the
transfer rate when you are backing up photos.
The main situation when you feel the difference is in the "random access",
when the system/program accesses many small files. (E.g. in case of a LR
database.)
Something else to add to this:
1. I would rely on a reasonable HDD much more than on a flash thumb drive.
2. HDDs (especially the cheaper ones, low grade "consumer" models.) still
have a good chance to fail. So, if some photos are really important to
you, you might consider having an additional backup copy.
3. When you are choosing the HDD model, - take a look at the reviews on
Amazon or Newegg.com - some HDDs have higher rate of failures, including
DoA. Read the lowest ratings for the contender HDD, and see what are the
problems that people are complaining about.
Note, that you will find negative reviews for ALL HDDs, it's the
percentage of those that matters.
4. IMHO, the "sweet spots" (price-wise) for the HDDs are now at 5-6TB, and
also for some drives at 2-3 TB.
5. While people have mentioned that CD reading rate will be the limiting
factor, - in the future, you'll continue using this HDD for backups.
So, - if your computer supports USB 3.0, I'd highly recommend buying a USB
3.0 HDD.
[If your computer doesn't have a USB 3.0 port, - it might be worth
considering options of adding a USB 3.0 controller to it.]
In my experience, even with a USB-2 controller, USB-3.0 external HDDs get
a slightly higher sustained transfer rate. (Though the difference is not
as significant, as in case of a USB 3.0 controller.)

The CD is going to be slower than any drive you connect it to. Don't
worry about rpms. Most externals are 5400 anyways. You'll spend a
premium to get a 7200rpm drive that is external and it won't really
gain you much in transfer speed though your random seek times will
improve. Something that doesn't matter when transferring large files
really.

thanks, never thought to look at rpm's

Almost certainly better transfer rate to an external skinny drive. Make sure
it’s a 7200 rpm Seagate. And thumb drives seem to fail frequently. At least
in my experience, although that’s based on use of recycled thumb drives that
I’ve gotten at press conferences.

I have decided, now that i have the time, to transfer all of my CD and
DVD back up photo disks to an external HD, I need a new one anyway and
Staples has a nice Seagate 2tb on sale. I also have a number of 32 gig
thumb drives i thought might also do the trick. Just curious would the
transfer rate be better from the CD player to externals as opposed to
thumb drives.?
