A byte is 8 bits.
A megabyte is a million bytes.
A gigabyte is a trillion bytes (or about 8 trillion bits).
Note : "about" because 1024 (2 to the tenth power) is used instead of 1000 (the base 10 that we normally use.
A thousand (or 1024) gigabytes is a terabyte.
1 megabyte is smaller then 1 gigabyte. 1 megabyte = 1/1024 gigabyes, 0.0009765625 gigabyes, or about 0.001 gigabytes.
you have it backwards, ~1,000,000 mb in a gb
I read 6 Terabytes which is 6,000 gigabytes 1 Terabyte is 1024 Gigabytes, so 6000 is actually incorrect. 6144 gigabytes would be correct. 144 gigabyes is enough space to store 10 or more full 1080 HD movies, so that is significant.
There are many things that can make a hardrive slow, space is not the biggest factor to this. However if you are running a newer build with vista and your drive is near full that's when space could effect speeds. On a older build 40 gigs is fine for the average emai-checker and web surfer. Keep it defragmented and clean. I would suggest a minimum of 80 gigabyes though.

Approximately 2000 (More like 200 or 100 if you rip the whole thing) I just ripped 105 movies, and they took up 366 gigs. I only copied the main movie, and not any other features or menus on the DVDs. Also, maybe about 5 of them were only about 25-30 minutes long, while most of the rest were full length movies. This is straight ripping without compression.
