HD wont work after Raid setup ???

If you want pure performance then you might want to look at Raid1. It provides fault tolerance so the array continues to work if one disk fails. The only thing is it operates in parallel so 2x80GB drives would give you one 80GB drive in parallel but the performance is far better than Raid0.

The best thing though would be Raid5, it basically combines Raid0 and Raid1 to give you the best of both. It also has fault tolerance so it'll still work when one of the drives fail. Only thing is you need minimum 3 disks to run this config.

Have a look here, find the one that works for you: http://en.wikipedia.org/wiki/RAID#Standard_RAID_levels

Raid0 should be avoided where possible.
 
To my knowledge raid1 and 5 use mirroring process, so each bit of data is written twice, whereas in raid0 the data is written once across both drives. I still believe raid1 and 5 is not gud for performance, raid 0 is.

The performance decrease when writing is minimal, in fact barely noticeable. But there is a better reading performance. And when you think about it, what does your drive do most of the time?

ok.
1. You admit there IS a performance decrease when writing, and logically the more data you write the more performance decrease one will expect.

2. You are right! The drive reads more than it writes, but how is it possible for performance to be better whilst reading? Remember when the drives are accessed in raid1 / 5 they are accessed as ONE physical drive, whereas in raid0 both drives are accessed simultaneously, which theoretically means you will have faster access time in raid0 mode. And faster write time. ;)
