I'm building a PC and want to use RAID 0 for the speed it offers but I would prefer to use 0+1 for the security as well. The question becomes what speed of HD am I going to use. The 10K speed hard drives cost about 2x the 7200s so I'm either going to buy two 10K drives and use RAID 0 or I'll buy four 7200s and use raid 0+1.

Any suggestions?

I cant help to consider data security as high on my list, so I would go with 0+1 or get a go with RAID 5 or something like a http://www.netcell.com/" target="_blank"> Netcell [/url} controller

Does RAID 5 give anywhere near the performance increase that you get from Raid 0? Raid 5 would be better than 0+1 because then I only need to buy 3 drives instead of 4.

Thanks.

RAID % is better than 1, but less than 0

The performance of RAID5 depends on the number of drives you use and the power of the controller. 3 drives would probably make RAID5 a little slower than RAID 0, but 4 drives might give it a small advantage. As you increase the number of drives you can go to exotic arrays such as RAID50, which gives you RAID5 and RAID0.
