The largest epub in my library is 295.3 MB; on a not very great 64 bit PC (old Intel CoreDuo CPU) Calibre converted it to azw3 in under 20 seconds. The copy was slightly greater in size at 299.7 MB. Of course the integrity of the copy cannot be tested on a Kindle, but appeared perfect in Kindle for PC.
The reason is probably pretty obvious to most in that most of the volume of a large epub, for example, is as has been said by others, images. The images are of little overhead for the conversion, they being files that are simply transferred to the new book.
But, as Katsunami says, a large book comprising mostly of text and formatting may pose a problem.

Even then, I usually found that if you give it enough time (and this could mean hours) calibre will eventually manage it. It will get bogged down, but it's not
crashing.
I have never understood the need for SD cards. The Kindle can still hold 1500 books (depending on the per-book avg. size) which should be enough even for a hoarder. I myself keep hundreds of books, many of which I don't plan on reading anytime soon, on my Kindle. Maybe that isn't a proof to anything, but it isn't necessary to have EVERY SINGLE BOOK YOU OWN on your device, visible to the ereader, and any attempt to do that may well be futile, whatever device you use. I would seriously suggest just keeping a nice thousand books, with the rest in calibre on your computer AND backed up to
Dropbox and/or
Copy.com is more than enough. And you will have enough reading material for at least a few months.
EVEN assuming you require extra padding in your library to cover all your bases -- lets say you decide you want to read "This" after you go on a road trip expecting to read "That", which I certainly can understand -- you will luckily have "This" too!
