Several of these drives are now available from the likes of Western Digital, and performance will suffer if Windows XP/2003 partitions are not aligned on these disks, because a whole 4K sector will be read/written for the sake of modifying one 512-byte block. (It's the RAID5 write hole, without the RAID.) Disk alignment DOES now make sense with single disks, when the disks use 4K sectors.

If (hypothetically) I had a server 2003 server with one disk, no RAID of any type. Just one single disk. Would that benefit from sector alignment? The question comes up via NFS shares and virtualization. If the VMs are published over NFS, I do not see a need for GOS alignment. It is not block based storage and therefor there is nothing to align to. -M Can someone tell me if sector alignment is even possible on a single disk?

For a long time it was the *only* official documentation I could find on disk partition alignment. Alas, it seems, like my darlin' Clementine, to be lost & gone forever.
