Warn about single disk RAID 0 arrays
Whole disks should be given to ZFS rather than partitions. If you must use a partition, make certain that the partition is properly aligned to avoid read-modify-write overhead. See the section on [[Performance_tuning#Alignment_Shift_.28ashift.29 | Alignment Shift]] for a description of proper alignment. Also, see the section on [[Performance_tuning#Whole Disks versus Partitions|Whole Disks versus Partitions]] for a description of changes in ZFS behavior when operating on a partition.
Single disk RAID 0 arrays from RAID controllers are not equivalent to whole disks. The [[Hardware#Hardware_RAID_controllers| Hardware]] page explains in detail.
