That's a nice score DR GEORGE!
DR TCB - your computer comes with so much space on its hard drive. If you get an external hard drive, you can store programs and photos and documents, etc, there and use less space on your internal hard drive. Your computer can run faster, I think.
I have 1 TB of memory on my computer, but most of my above named stuff is saved on an external 1 TB hard drive. It uses a USB cable and is always plugged in, so it is easy to use.
I am thinking about getting a larger one 2 or 4 TB so I can put even more stuff from my internal drive on it......
