Just a side note on the PERC labelled cards: they don't have a JBOD
mode so you _have_ to use hardware RAID. This may or may not be an
issue in your configuration but it does mean that moving disks between
controllers is no longer possible. The only way to do a pseudo JBOD is
to create broken RAID 1 volumes which is not ideal.
It won't even let you make single drive RAID 0 LUNs? That's a shame.
The lack of portability is disappointing. The trade-off though is
battery backed cache if the card supports it.
