[stylist] logistics question

[Brenda]

Good morning list

One of the chapters of my writing class is about keeping a journal.

I would like to have my writing transferable from my desktop to my 
laptop so I can write spontaneously.  (Of course, I would keep a copy of 
everything on each computer in case of loss or damage to the portable 
media.)

I had thought about using a thumb drive, but wonder if an SD card could 
also be used?  I like the smallness of an SD card but wonder about its 
durability.

Thanks for your input.
