Well, not so simple so that I'm missing out on stuff, but simple enough for someone who wants to just touch on the topic to get an answer. –  William Nov 30 '11 at 19:55
    
NTFS is a journalling filesystem, see Wikipedia for instance. –  arrange Nov 30 '11 at 21:00

PC World: Ubuntu Linux, Day 16: EXT4 vs. NTFS

Any discussion around 'why/why not' and 'defrag' needs to include Diskeeper (formerly Executive Software). Offering to license your product to Redmond, and having your company and/or product still be viable in two years, is a Herculean adventure at best ..

Thanks for your quick answer. Your'e going to need more then 30 days to see if ext4 makes a difference, though. How large of a file size can ntfs support? 16 terabytes is an awful lot of data. –  William Nov 30 '11 at 20:05
    
The was their '30 days', and you should direct such comments to them .. –  david6 Nov 30 '11 at 20:41
