RAID card questions

I'll be ordering one of the new MPs shortly to replace my 3 ghz quad. While I use the OSX software RAID on 3 external Sonnet Fusions, I've never attempted to RAID the internal drives. Ideally, I'd like RAID 5 on the 4 internal drives on the new machine, but that would necessitate a RAID card. There seems to be (and I may be wrong) two different RAID cards in the Apple store - one for the late 2009 MPs and an older one that has many complaints concerning battery problems.

I could stripe the four drives and have more capacity but I like the idea of the RAID 5 drive failure tolerance. I know there are other RAID cards available but I'd rather stay with the Apple card if it would work well as my knowledge/skill in these areas is scant and I don't want to get in over my head.

Are the newer cards that come with the early 2009 MPs reliable or am I just asking for trouble?

I would forgo RAID5 internally.

Or just setup a 3-drive mirror. Very fault tolerant. And cheaper. If you want your mirror with stripped reads, that really helps performance, go to SoftRAID.com

If you have never attempted internal RAID, and I assume boot drive, use it for scratch for awhile first to experiment.

I like to have a dedicated boot drive, OS and apps, and nothing else. Very simple and easy to maintain.

The older units did have trouble, and also limited to 340MB/sec.
