To make the long story short about my iPod in Recovery Mode problem thread, is it normal for my computer to backup and Sync over 13gb of data in like..5-15 seconds? I have a new, crazy fast computer so I'm not sure if it really Synced. I don't wanna restore and notice that no data was really saved or I might go crazy...
If you mean it backed up very fast, then that's pretty normal. The backup won't actually contain everything on your device, it only contains the device's settings and the settings you have selected for when you sync it with iTunes. Even if you restore and then set it back up using your backup, it won't actually have all your music, videos, photos, apps, etc back on it - they will still need to be in iTunes to sync.
As for actually syncing 13GB of data in that short a time - absolutely impossible. No matter how fast the actual computer may be, only a certain amount of data can be transferred over USB at any given second. If you mean you already have all your content on your computer and you're trying to sync it to the iPod, the above user would probably be correct - it seems more like a botched sync than anything else. I'd say it should have taken 10 to 15 minutes for your iPod to sync that much data - it takes about 25 minutes to sync 30GB of data to mine.
