Sequential reading is a simple task, so the results please the eye of the tester with uniformity: the Deskstar 7K400 is slightly faster than its predecessor in NTFS, especially coupled with Serial ATA controllers. All participants are peers in FAT32, if we make allowances for measurement errors.
Copying files is a more complex task, with certain nuances possible. For example, I can remember hard drives from Samsung easily beat their opponents with a higher “linear” speed. Let’s see if there are any changes in this respect with Hitachi.
The changes are obvious even at copying from one partition of the disk to another: the Deskstar 7K400 on Serial ATA controllers are much faster in NTFS and remain overall winners, even despite the minor loss in FAT32. Note also that the Deskstar 7K250 are fastest in FAT32.
The Serial ATA controller from the ICH5 South Bridge lost its ground when copying from one partition to another. The Deskstar 7K250 almost overtakes it even in NTFS. This drive becomes an overall leader thanks to its excellent performance in FAT32.
