Dell often says part X is included, but part X is not the exact same aspart X sold by the original manufacturer. To hit a specific price point, Dell is willing to strip thing out of commodity hardware, and often does so even when performance suffers. For many people, this is unacceptable.
The last dell box I bought, a PE1850, came with a PERC 4e/Si card, which I believe is the same as the card the OP was looking at. It is very fast in RAID1 with two U320 disks.
For real DB work, I'd look more to a dual channel card and have 1/2 of each mirror pair on opposing channels. Dell can configure that for you, I'm sure.
I think the well tossed-around notion of Dells being underperforming needs to be re-evaluated with the EM64T Xeon based systems. They are quite fast. I haven't put a very large db with extreme loads on any of these systems, but the simple benchmarking I did on them shows them to be acceptable performers. The high-end RAID cards they sell these days do not seem to me to be skimpy.
Now if they'd only get on the Opteron bandwagon....
