Question about software RAID

[Brandon Shiers]

Hi folks!

Just got FreeBSD running on both my E250 and also my SunfireV120.  I'm 
loving it.  Much better than that Solaris stuff :)

Quick question for folks on the mailing list:

Are any of you running software RAID?  I'd like to setup some RAID-1 
with hotspare drives on both my boxes.  

Is ccd or vinum better for this?  For the folks using one or the 
other, what significant, if any system overhead/problems has using 
either of these pieces of software caused?  

TYIA!

Brandon
