IMHO, Hardware raid primarily exists because of Microsoft Windows and
VMware esxi, neither of which have good native storage management.

Because of this, it's fairly hard to order a major brand (HP, Dell, etc)
server without raid cards.

Raid cards do have the performance boost of nonvolatile write back cache.
 Newer/better cards use supercap flash for this, so battery life is no
longer an issue

That said, make my Unix boxes zfs or mdraid+xfs on jbod for all the reasons
previously given.
