Ah, I love your good answer. I remember this from the past:

Why my $20 adaptec RAID card (they were "software" RAID) doesn't
work as
well (if at all) as your $700 3ware or LSI (megaraid) or Areca card?

actually, I prefer the LSI 'HBA' cards in IT mode, with the raid
functionality completely disabled, and use the host OS's storage
management, ZFS on FreeBSD or mdraid+lvm on Linux.    Only place I would
use a 'true' RAID controller would be on a Windows Server as Windows
software raid is awful, ok, and on a VMware ESXi server, as its storage
management is awful, too.   But on that latter, I would MUCH rather use
NAS/SAN storage.   And on the Windows server, I would much rather it be
virtualized.

Well, everybody's mileage varies. If one is going to use zfs, then no 
hardware RAID can beat that, i.e., zfs ensures data integrity, whereas 
hardware RAID can sometimes guess, which stripe on which physical drive 
has corrupt data, but not always. On the other hand, if one refuses to 
use zfs, as it is owned by Oracle now, so one alleges its future is 
unpredictable, then it is only a question of "taste", some may argue 
software RAID is better, others: hardware RAID is better. The last would 
be me; my argument: hardware RAID has dedicated processing hardware and 
very short, hence well debugged software as opposed to the whole system 
that is capable affect software RAID. All in all, I do not suggest 
everybody accept my argument as correct, as I said, is a question of 
taste for me. Or, borrowing the phrase of my friend "you go your church, 
I go mine" ;-)

Anyway, it is distributed file systems now, whenever we go for big 
storage...

Thanks.
