Hello everybody,
For a long time, I was wondering about a safe and also fast storage solution that's protected against drive failures. The solution of choice would be RAID5.
Since I'm not a company but an individual, high-priced server solutions were out of scope. In the last months, several motherboards came out with RAID5 capable controller chips integrated on them. As my current everyday used config is almost 3 years old (Socket 462), it is an attractive alternative for me to change the whole platform also.
I know that RAID5 needs parity calculation on the fly, and in case of motherboard integrated controllers, this task is done by the main processor, as it's also the case with cheap standalone controller cards. This solution is less-performing and more resource-consuming by its nature. But the question is : how much less performing ? I want the RAID5 solution having the best price/performance ratio.
I've searched the net a lot for integrated mobo RAID5 reviews, found none.
I'm especially interested in the performance of the following chipset solutions :
- nVidia 430 SouthBridge
- ULI 1575 SB, 1597 NB
- ATI's still-not-released new SB chip SB600
- Intel Matrix Storage (ICH6R/ICH7R)
If anyone has info or can link to sites having RAID5 performance comparisons regarding these chipsets, please post that here.
Cheers,
Peter
