This can best be explained with an excerpt from the Mp3/Tag Studio help file (from the page regarding the "Tagging Core Settings" section of the global settings):
| Quote | Super fast v2 tagging:
When you write an ID3v2 tag to a file that does not have a previous v2 tag (or that has a smaller v2 tag than the one you are about to write), that whole file, including all sound data, must be rewritten to the disk. This is due to technical limitations in harddisk filesystems in combination with design issues of the ID3v2 tag, and there's nothing I (or anyone else) can do about it. The problem is that this might lead to several megabytes of data being written to the disk, even though the new tag data only consists of, say, a few hundred bytes. This in turn will of course affect the time of the write operation quite seriously. Due to this limitation, writing ID3v2 tags to files often takes much longer than writing ID3v1 tags to them. Normally that is...
When you activate this setting (i.e. "Super fast v2 tagging", on the "Tagging Core" page of the global settings), you agree to sacrifice a very short bit of sound data (approximately 0.03 seconds) in the beginning of every file the first time you add a v2 tag to it, and in turn the operation will be just as lightning fast as writing an ID3v1 tag! There might be some reasons for why you don't want to do this in some situations (e.g. if the music of the track actually begins within the first 0.03 seconds of the mp3, but this is mostly not the case), and that's why I made it optional. But for doing ID3v2 tagging on e.g. a network drive or other slow media it is a lifesaver, I assure you. Just try it and you'll see what I mean... |
I also think the situtation is made even a little worse for you speed-wise, because you use an external harddisk.
