Scott, |

I have a 3Ware Escalade 4 chaneel hardware raid controller running raid |
| 3 |
10. Here are my thoughts: The card itself was $175.00 and the 4 250GB |
| 4 |
brives were $150 bucks a piece, so the cost is considerable. If you are |
| 5 |
only going to have two disks mirrored, you can get the two channel card |
| 6 |
and two drives and mirror them which is obviously less money. My system |
| 7 |
is a Tyan Transport GX-28 with 2 Opteron 246's and originally I had the |
| 8 |
drives on the onboard controller. First, there is a very noticable |
| 9 |
increase in performance going from the integrated (software) raid |
| 10 |
controller to the hardware raid controller. For my percieved needs it |
| 11 |
was definitely worth the money. Second, its a nice reassurance to know |
| 12 |
that if a drive (or even two drives) fails the hardware controller can |
| 13 |
restore the array by popping in a new disk without me having to do |
| 14 |
much...I'm not sure if this is the case with the integrated or linux |
| 15 |
raid. With the hardware controller, if I wanted a bit more storage |
| 16 |
space, I could have chosen to make a raid five array, something that as |
| 17 |
far as I know is unavailable in both integrated and Linux array (at |
| 18 |
least now without a significant performance hit.) Hope that helps. |
