You can negate this a little with the following tips:
* By default NTFS will automatically update timestamps whenver a directory is traversed. This isn't a necessary feature, and it slows down large volumes.
Disable it by pointing regedit to:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem and set 'NtfsDisableLastAccessUpdate' to 1.
* NTFS uses disparate master file control tables to store filesystem information about your drives. Over time these core MFT files grow and become fragmented, slowing down all accesses to the drive. By setting aside a little space, MFT's can grow without becoming fragmented. In the same key where you disabled the last access feature creat a new DWORD value called 'NtfsMftZoneReservation' and set it to 2.
Note: This tweak will not work on FAT32 file systems!
