I think it is simple (not very simple) , and in the same time extremely good idea. Ah, false modesty, who needs you …MFT. It is all about MFT file. A “feature” of the, otherwise very good, NTFS. By now a good old, file system of Windows. Invented for NT 3.51. (Wow, that was a long time ago!)
Here it is: change W7 NTFS so that MFT file is always created from the END of the disk! Not from the TOP! Avoid mixing of MFT and all the oher files, as it is the case now. Today if MFT is fragmented tough luck. Defrag tools can not touch it. You have to use the special MFT defrag tool and even worse, you have to reboot to defrag the MFT file.
This way MFT file will almost always stay in one piece, it will not be fragemented on 99.9% of machines running W7. Automagically W7 NTFS will be faster and more resilient. Simply W7 NTFS will create MFT and place it on the END of the disk when it installs itself.
MFT on the standard NTFS can be defragmented only before login happens. In the twighlight zone of the blue screen only. True, there are tools for MFT defragemnting. But they are never used by 99.9% of the population and more importantly professionals are not rebooting their data centres just to be able to defrag the MFT!
W7 server will be extremely popular if NTFS will have MFT which is never fragemented. Of course ALL the other W7 NTFS system files could be located at the END of the disk, on the safe distance from standard files, and thus most likely kept in one piece each. Paging file (of a fixed size), hybernation file, etc … No defrag of W7 NTFS system files needed !
