I know it's a stupidly minor thing, but the OCD in me won't let it go.
For internet speeds, you're gonna want to use the small b there. Mbps, not MBps. Source: I work for an ISP, and if you want to check for yourself go look at your bill/statement/online ads/comcast.com/att.com or whatnot. They all sell internet speed at the Mbps level, never at MBps (because that number would look smaller by comparison, and people don't like small numbers. True story).
So, with a 100 Mbps connection (Megabit per second, not MegaByte) you're essentially pulling 12 Megs (12 MegaBytes) every second. A little over. 12 and a half.
6,000 MB (super rough rounding for GB, I know its 1024 x 6 for the even more less-rough number) divided by 12.5 MB per second is 480 seconds. Assuming ZERO other traffic utilizing your pipe, you're looking at 8 minutes to download.
8 minutes to download a 6 gig file with a 100 megabit connection.
Edit: and yes, I'm AMAZING at parties.
Edit 2: ALSO ALSO, I'm assuming the OP meant 6 GB, and not 6 Gb. Because 6Gb is only 750 megs or so. 750 MB. Damn those small and uppercase B's! Damn them to hell!
