I bought a rocketraid controller ; wanted to use it as a plain SATA
interface so I put all disks as JBOD.

Turned out, the disks were unusable without the rocketraid.

Same thing with RAID1; it partitioned the drive in such a way that
they would appear empty if connected to a plain SATA controller.

So hardware RAID aren't that much better either.

md on Linux has proven to be extremely reliable, recovering data in a
RAID5 array, even after 2 drives got disconnected.
