Drives store data on the outer tracks of the platter first, moving in towards the center as you store to higher numbered blocks/sectors. Referring to the graphic used in the partition section of Disk Utility, partitions closer to the top of the screen are on outer tracks. Moving down towards the bottom of the screen implies placement further "down" the disk and on the more inner tracks of the platter(s). At least that's how I've always understood how it works. The difference in the sequential access rates arises because the tracks on the outer edge of the platter have a higher tangential velocity than those nearer the center. (Simple playground merry-go-round physics) It can be argued that one will never see enough of a performance gain to be worth the hassle of dividing a drive into two partitions and constantly worrying about how to juggle your data between them. But since I'm one of those folks who likes to fiddle with their computer just for fiddling's sake, it's something I might try just for the sake of trying it. -irrational john -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
