Be careful when talking about RAID controllers in general. They
are
not created equal! ...
Hardware raid controllers have done the job for many years ...
Not quite the same job as ZFS, which offers integrity guarantees
that RAID subsystems cannot.
Depend on the guarantees. Some RAID systems have built in block
checksumming.
Which still isn't the same. Sigh.
Yep.....you get what you pay for. Funny how ZFS is free to purchase
isn't it?
As Nathan and others have pointed out, ZFS offers more integrity
*because* it's software.
And does anyone really believe, these days, that "you get what you
pay for"? ISTR Vista "Ultimate" is considerably more than a Solaris
license. Rock on.
