Install question, RAID

Question for you guys, I am going to do a RAID, I have 4 1TB drives ( 1 seagate, 3 WDs that are the same), is it better to raid them all and install arch to that? or Should I install Arch to the seagate and do a RAID 5 on the other 3 TB drives?

Re: Install question, RAID

I would raid them all together as I would want the speed and backup advantages for everything.

Re: Install question, RAID

RAID5 has performance setbacks with random writes and simultaneous small writes.  If you want good speed and reliability but at the cost of having 2TB of total space, use RAID 0+1.  Most mobos support 0, 1, 0+1, and 5.

Edit: I don't trust really high capacity drives (basically everything over 800GB).  I've read so many reports of failures, I wouldn't want to risk all of my data.  So RAID 0 seems pretty much out of the question.
