RAID Solution

I will be buildig a new system i the next few months, trying to plan it out now. I will be using a RAID 5 Array for archiving and general data storage (need about 500MB plus some room to grow). I am trying to determine the best course of action to run the RAID array. I have 3 options:

MB I am looking at is MSI K9N which has onboard RAID that can do RAID 5
RocketRAID 2300
Areca ARC-1210

Number one thing I am looking for is stability/reliability, after that cost and performance tie for 2nd place. Any input?

Thanks!
 
I would use the MSI on-board RAID. It does everything you want, and no added things are needed.
 
The Areca would probably be the most "serious" and reliable etc,. at obviously the greatest cost. But it'd be overkill to spend so much on a controller and overlook a backup, so with the 2nd priority, you'd be better off spending some of that money on an external backup drive or something to that effect instead of on the controller.

The onboard RAID 5 solution will have "bleh" class write performance. The RocketRaid would do better, although it isn't a pure hardware solution either. It's probably a reasonable "balance" bet.

I'd wait until purchase time to make the final decisions. Perhaps the HD price war will have heated up a bit more and you'll get lucky with some larger capacity options. Consider RAID 1 as well then if the sizes allow. Greater simplicity = greater reliability.
 
Thanks for all the input. I have RAID 1 now, performance is fine, but n/2 on the amount is what I don't like, not real efficent, but stable. RAID 5 is efficient, but more complex, however it is mature technology that has proven well. I also like n-1 for size, much better than n/2.

I liked the Areca, but as was illustrated cost is much higher, I though the RocketRAID would be a good balance. My concern with the RAID5 on the MSI built in RAID is the speed, that is a lot of computations with out the propper ASIC, I could see a noticable performance hit. If i did RAID 1, I would use the one board though.

Thanks for the input!
