Hello friends, this is my first post on this forum so please enlighten me on this issue even if it sounds silly..... :roll: I've read so much about raid (0, 1 0+1) these days but never come across any article which has mentioned setting up a RAID of more than two disks....my questions are : - 1) A motherboard which might have three raid controllers, in reality how many disks are possible to be set up in raid configuration because all i've read is that a single controller supports a maximum of 4 disks, so lets say if i want to get a six disk RAiD setup, is it possible to simultaneously use 2 raid controllers- one with 4 disk and another with 2 disk. Or we can only use one raid controller at a time from a motherboard having 3 controllers???? If this is the case then why do some mobo boast of 8 sata connectors??? 2) Is it possible to use 2 disks (out of 4 HDDs) as a RAID 0 or 1, and the other two HDDs as non-RAIDs, in the same raid controller?? 3) Does having a RAID 0 setup effect the life of hard drives??? Are HDD more prone to failure in RAID 0 setup or the chances would be the same as any normal non-RAID drive?? 4) Will having a 4 disk raid setup improve performance substantially or will be it meagre compared to 2 disk setup.Which would be better :- (A) 2 western digital raptor, 75 GB, 10000 RPM OR (B) 4 (disk) 160 GB 7200 RPM sata drives in terms of performance (in RAID 0 setup)? 5) Finally, what are disk failure rates, coz personally have never seen a disk fail till date. Is it really something that should make us go for a RAID 1 setup???? Well these are a volley of questions, but would really appreciate if you could share your knowledge on all/any of these points......Thanx in advance dudes!!!!
