Regarding the slow write performance on the first partition of a
partitionable RAID-5 array, actually this is not linked with the first
partition. This issue happens when the partition does not start on a
cylinder, and this is almost always the case for the first partition
which does not start on the first sector of the first cylinder (some
space is reserved for the partition table).
This symptom doesn't exist on RAID-1.
Does anyone know why ?
