[TriLUG] raid cards

[Brian Weaver]

I have two 3ware hardware raid cards and I concur with Jason; they are
great. That being said I don't think I would go with a *Hardware* RAID
solution again for any Linux box that I build in the future.

My main concern is that if one of my 3ware RAID cards die, how am I
suppose to get the data off the drives? I don't know how 3ware chose
to write that information or maintain the array information. So I'm
stuck with trying to find a new compatable card at what may be an
outrageous price.

With software RAID the particulars of the implementation is open. If
your MotherBoard or Disk Controller dies then you can just replace it
so long as the hard drives themselves are OK.

Just something to consider
