Hi. In a RAID Array 0 or 1, should the IDE drives be connected as Master and Slave in the same channel or as Master, Master in different channels. Althou It will work either way wich way is best? Thanks Once upon a time the floppy disk was king.

Why do you wanna run a RAID config at all? And you've chosen two completely different types of arrays. You need to decide what you want, speed or redundancy. RAID 0 has a slight speed advantage over a single HDD, but it has no fault tolerance...if one drive fails, you lose everything with no chance of recovery. Technically, RAID 0 isn't RAID at all since there is no backup (redundancy). RAID 1 uses one drive for mirroring so in effect, you only have 1/2 the drive capacity. In other words, if you have two 100GB HDDs, you don't have 200GB capacity, you only have 100GB because the 2nd HDD is a backup copy (mirror) of the 1st. RAID 1 is slightly slower because of the double writes. That being said, a master/master config is usually faster than a master/slave config.

Master/Slave would be ok as long as they are on different cables (controllers). But as Jam said, having them as Master/Slave on the same controller would slow it down.
