I'm ripping my DVDs to hard disk in file format, not Iso and I was wondering what cluster (block) size should I use on the hard disk partition I'm going to store them on? I don't want to waste space by using too large a cluster size but also don't want any stuttering problems caused by too small a cluster size. I know that for big files like Mpegs 64k clusters are preferred. Should I use this size or should I use the standard 4k clusters. Thanks.
